| Form 990, Part III, Line 1, Description of Organization Mission: | BrightFocus Foundation seeks to save mind and sight by funding innovative research worldwide and by promoting better health through education. We focus our efforts on three incurable diseases affecting mind and sight: Alzheimer's disease, macular degeneration, and glaucoma. Collectively, one in 16 people over the age of 40 in the U.S. alone has one of these diseases. BrightFocus has a proven track record of supporting the most innovative, early-stage research seeking better understanding, treatments, or, ultimately, a cure for these diseases. Since 1973, BrightFocus has awarded more than $140 million in research grants to thousands of scientists around the world. Our research funding has led to major contributions to the understanding of these diseases and to the awarding of two Nobel prizes. BrightFocus-supported findings are consistently cited by other scientists at twice the frequency as other research findings. Our funding acts as a catalyst in early-stage research. The BrightFocus research programs are designed to provide initial funding for highly innovative experimental ideas. Due to the structured grant review and approval process, most recipients of BrightFocus funding go on to receive future grants from other sources that are 10 times larger than the original BrightFocus award. This one thousand percent return on BrightFocus investment speaks to our ability to identify promising research and spawn future scientific discoveries. It is our firm belief that having the courage to invest in innovative ideas will lead to revolutionary approaches and life-saving breakthroughs. Indisputably, the world-class research identified and supported by BrightFocus is more than promising: it is making a real contribution to revolutionary science in the fight to save mind and sight. Along with funding cutting-edge research to find cures to some of society's costliest diseases, BrightFocus also provides free educational materials and support to hundreds of thousands of patients and families affected by these diseases nationwide. BrightFocus increases public awareness of Alzheimer's, macular degeneration, and glaucoma, and communicates with elected officials about the importance of scientific research in these areas. BrightFocus' award-winning Public Service Announcements (PSA) have appeared on television, radio, and in print throughout the nation. Both Now is the Moment to Stop Alzheimer's Disease and See a Better Tomorrow powerfully seek to raise awareness and early detection, and similar messages have been delivered through donated print PSA space in airports and train stations, as well as at pharmacies and supermarkets. In Fiscal Year 2014, these PSA messages generated $17,597,705 in donated media services and garnered 1.5 billion impressions. We held three community forums on brain and eye diseases, and recently launched BrightFocus Chats, a free, interactive monthly telephone forum that brings together patients and caregivers to learn from, and ask questions of, leading researchers and specialists. We have launched the series through discussions related to macular degeneration, and hope to expand the program into other disease areas. The Chats are archived on our web site, with audio and print transcripts available in a number of accessible formats. We continue to increase our print publications, many in Spanish, that provide helpful information to patients and caregivers, and regularly unveil new video and audio resources in conjunction with allies in the medical and scientific communities. We have expanded our written content of key research findings, promoting and sharing this information through our web site and social media platforms. Capitalizing on emerging use of data visualization, our BrightFocus "Snapshot" series graphically communicates information on detection and treatment of macular degeneration and glaucoma. Through our social media and web resources, we conduct contests and promotions to increase awareness of these diseases and further share BrightFocus publications and events. For example, our Healthy Recipe Contest drew attention to the importance of preventive lifestyle choices, and through over 6,000 on-line votes in the Geoffrey Beene research challenge, we increased public exposure of the need for increased scientific research on gender differences in Alzheimer's. More specifically, each of these program areas mail awareness-raising materials to hundreds of thousands of households, with messages focusing on: -Symptom recognition and steps the public should take, such as making an appointment with the doctor if symptoms exist. -Lifestyle choices that promote good health, encouraging readers to take action to reduce the likelihood of the onset of the disease. -Research results and treatments available to address the disease. BrightFocus regularly interacts with members of the media, as well as elected officials and federal agency staff. We communicated to policymakers the results of our survey of leading researchers, showing the dire consequences of cutbacks in federal research budgets. Through media interviews and placements, as well as participation in advocacy coalitions, we help advance the cause of pioneering science and better expose BrightFocus as a resource for those struggling with, and searching for cures for, these terrible diseases. |

Each board director, officer, and employee is required annually to complete a conflict of interest disclosure statement. Employees meet annually with the BrightFocus Chief Compliance Officer to review their conflict of interest statements, and gives an annual conflict of interest compliance report to the Board Chair and Vice Chair. If a conflict is reported, it is then referred to the CEO and/or BrightFocus legal counsel and, if appropriate and necessary, then to the Board of Directors or its appointed Committee for further action. The director's and officer's statements are reviewed by the BrightFocus legal counsel. If a conflict is reported, it is then referred to the Board of Directors or its appointed Committee for further action. At the time of the BrightFocus discussion and decision concerning a conflict of interest, the conflicted party is not present in the meeting. |
| Form 990, Part VI, Section B, line 15a | The BrightFocus Foundation (BrightFocus) Board of Directors has overall authority and responsibility for approving the annual budget which includes compensation for all employees at every level including non-director officers. All pay adjustments are made on a yearly basis effective April 1st, the beginning of the BrightFocus fiscal year. Before approving the compensation of the CEO, the Board determines the total compensation to be provided by BrightFocus to the CEO is reasonable in light of the position, responsibility and qualification of the position held including the result of an evaluation of prior performance for BrightFocus, if applicable. The CEO is evaluated annually by the Board of Directors through the use of an in-depth goal attainment structure, (developed with advice from Board Source) that includes a self assessment and a Board of Directors assessment and evaluation against set goals, outcomes and deliverables. In addition, the Board of Directors periodically engages an outside consultant to obtain and consider appropriate data, including a salary survey, which includes information compiled from the federal Form 990 of other organizations, concerning compensation paid to CEOs in like circumstances. In making the determination, the Board of Directors shall consider total compensation to include the salary and value of all benefits provided by BrightFocus to the individual in payment for services. At the time of the BrightFocus Board discussion and decision concerning the CEO's compensation, the CEO is not present in the meeting. The Board shall set forth the basis for its decisions with respect to compensation in the minutes of the meeting at which the decisions are made, including the conclusions of the evaluation and the basis for determining that the individual's compensation was reasonable in light of the evaluation and comparability data. |

Investigators Summary: What genes affect the optic nerve and put it at risk of glaucoma? Knowing which gene changes increase the risk of glaucoma will enable us to diagnose people early and allow treatment to prevent blindness. We have previously measured photos of the optic nerve of 1400 20-year olds and identified genes associated with the size of the nerves. We now propose to analyze high resolution scans of the same nerves to search for new genes. Grant Awarded: $99,550. Lions Eye Institute, Nedlands, Australia. Region: Middle East and North Africa (D) Purpose of Grant: Alzheimer's Disease Reasearch by Michal Schnaider Beeri, PhD Entitled: (A2014268S) Vascular Function and Cognition in Type 2 Diabetes. Investigators Summary: The risk for cognitive impairment and Alzheimer's disease is increased in patients with Type 2 Diabetes (T2D), potentially due to impairments in the structure and function of blood vessels in the brain. Previous studies have shown that the problems of the functioning of blood vessels, which can be treated and reversed, is impaired before the structure of blood vessels becomes impaired, and that treatment of impaired blood vessel functioning may prevent impairment in its structure, which is irreversible. In this application we propose to study the role of blood vessel functioning in cognitive impairment in T2D patients and how different factors within T2D (for example glucose levels in the blood) affect this relationship. The results of this study may help develop treatments for the prevention of cognitive impairment in T2D and may help better understand factors that affect deleteriously cognition in all elderly.

Region: Europe (D) Purpose of Grant: Alzheimer's Disease Reasearch by Elena Marcello, PhD Entitled: (A2014314F) Validating ADAM10 as Therapeutic Target for Dementia. Investigators Summary: Alzheimer's disease affects a number of elderly people, who lose their memory and their ability to take care of themselves. Such disease is caused by a substance that kills neurons. Our work is intended to develop a drug able to promote a pathway in the cell that limits the formation of this substance. We hope that our results will contribute to help people suffering of Alzheimer's disease to recover their memory. Grant Awarded: $120,000. University of Milan, Italy |

Grant Awarded: $50,000. University of Luxemburg, Luxemburg. Region: Europe (D) Purpose of Grant: Alzheimer's Disease Research by Rik Ossenkoppele, PhD Entitled: (A2014083F) Tau, AB and Network Degeneration in Alzheimer's Disease. Investigators Summary: Alzheimer's disease is characterized by the protein amyloid-beta that emerges 15 years before symptom onset, but its working mechanisms are not clear. Animal and post-mortem studies suggest that tau proteins may be the missing link between amyloid-beta and clinical symptoms, and since very recently, this protein can be visualized in the living human brain using positron emission tomography (PET) scans. We propose to study the role of tau in Alzheimer's disease patients by investigating its relationships with amyloid-beta, shrinkage of the brain and communication between brain cells. This study will lead to better understanding of the disease and could stimulate development of novel therapeutic agents to prevent or slow-down the devastating effects of Alzheimer's disease. Grant Awarded: $120,000. Alzheimer Center of the VU University Medical Center, Amsterdam, Netherlands. Region: Europe (D) Purpose of Grant: Alzheimer's Disease Research by Carlos Saura, PhD Entitled: (A2014417S) Transcriptional Mechanisms of Memory Loss in Alzheimer's Disease. Investigators Summary: Memory impairment is one of the earliest clinical features of AD, but the cellular events that cause brain dysfunction and memory loss are largely unclear. Memory processing depends on activation of gene expression programs in specific memory neuronal circuits. In this project, we will study the transcriptional mechanisms of gene regulation underlying memory processing in normal and AD pathology conditions. This information will be valuable to understand the causes of memory circuit dysfunction and develop novel and innovative therapies for the treatment of memory loss in AD. Grant Awarded: $249,000.

Name of organization or government: University of Pennsylvania School of Medicine (H) Purpose of Grant or Assistance: Alzheimer's Disease Reasearch by Jing Guo, PhD Entitled: (A2014005F) Mouse Model for Sporadic Tauopathies. Investigator's Summary: Accumulation of misfolded tau protein in neurons is a hallmark lesion of Alzheimer's disease and many other neurodegenerative diseases. Recent studies have demonstrated that misfolded tau can spread from one cell to another and corrupt the folding of normal tau in healthy cells. We will utilize this mechanism to create a mouse model mimicking sporadically-occurring neurodegenerative diseases with tau aggregation. We will also explore the existence of distinct forms of pathological tau in different diseases. Name of organization or government: University of Rochester Medical Center (H) Purpose of Grant or Assistance: Alzheimer's Disease Reasearch by Gail Johnson, PhD Entitled: (A2014018S) Nrf2 Regulates Tau Clearance: an AD Treatment Strategy. Investigator's Summary: This focus of this study is to determine how brain cells get rid of excess tau protein. This is important because in Alzheimer disease there is a buildup of tau protein and this contributes to the ill health and eventual death of the nerve cell. We are focused on a particular system that identifies proteins that are no longer needed and engulfs and digests them. This system is called "autophagy" and in Alzheimer disease brain it is does not work efficiently. Therefore finding ways to make it work better and to selectively target tau for clearance could be beneficial to people who have Alzheimer disease. We have found that one way to improve the removal of tau from the neuron by autophagy is to upregulate proteins that make the process work better and directly deliver tau to the autophagy machinery. We have found that chemicals in foods like broccoli and green tea can cause increases in autophagy and decreases in the levels of tau. In this project we will determining how these types of chemicals improve the ability of nerve cells to get rid of excess or damaged tau protein. We will be doing this, using studies both in nerve cells that we grow in dishes and in mice. These studies will help us understand how a nerve cell normally gets rid of unwanted tau protein, what might be going wrong with this "disposal system" in Alzheimer disease and what we can do to make it work better. |

Investigator's Summary: Binding of a fluorescent form of the human-specific amyloid imaging ligand PIB will use flow cytometry to isolate synaptosomes from Alzheimer's disease brain to identify the type of nerve cell carrying the PIB binding amyloid pathology. The biochemical components of the synaptosomes will be determined by high sensitivity high resolution mass spectrometry. Comparison with synaptosomes isolated from a mouse model of Alzheimer's pathology with similar identifying neuronal markers will be used to identify candidates that could account for the lack of significant PIB binding in animal models and their failure to progress beyond very early AD stages to neuronal cell death and dementia. Future studies will investigate the manipulation of the candidates to increase PIB binding to better model the human AD phenotype. Name of organization or government: University of Florida (H) Purpose of Grant or Assistance: Alzheimer's Disease Reasearch by Yona Levites, PhD Entitled: (A2014105S) Targeting Intra vs Extracellular Tau by Recombinant Antibodies. Investigator's Summary: In our search for potential modifiers of Alzheimer's disease (AD) pathology in mouse models, we have developed a "somatic brain transgenics" paradigm, established by delivery of genes packaged into adeno-associated viral vectors and injected into the brains of newborn mice. Tau protein is known to go through abnormal phosphorylation and accumulation in AD for yet unclear reasons. Anti-tau immunotherapy has recently emerged as a promising approach to target tau, but many questions regarding the optimal form of anti-tau immunotherapy remain open. We propose to compare the ability of recombinant intracellular and extracellular antibodies to attenuate tau pathology in two mouse models. These studies will provide critical insights into i) whether targeting tau in the extracellular vs. intracellular compartment is more efficacious and ii) whether full length antibody and not just its binding fragment antibody effector functions are required. Name of organization or government: University of Florida (H) Purpose of Grant or Assistance: Alzheimer's Disease Research by Guilian Xu, PhD Entitled: (A2014108S) Protein Homeostasis in Mouse Models of Alzheimer Pathology. Investigator's Summary: In this proposal, we investigate fundamental changes that occur in way nerve cells manage the production of new proteins and the disposal of old proteins. This process is essential to the normal functioning of the brain. In work prior to this proposal, we have identified a new pathology associated with Alzheimer's disease that we call secondary misfolding pathology, which describes changes in the ability of nerve cells to produce functional enzymes and proteins. In this proposal we will be working to better understand how this new pathology we have discovered may be affecting the ability of brain to function. |

Investigator's Summary: To understand why your friends or relatives develop Alzheimer's disease (so-called etiology), we need to develop bio-markers that can evaluate the disease progression as well as the underlying disease processes, especially those related to toxic AB accumulation in brains. Recent studies, including our study, demonstrate that synapses (neuronal connections in brain) play important roles in toxic AB accumulation. By elucidating how these synapses regulate the metabolism of toxic AB in brains at a molecular level and what proteins or molecules in body fluids are associated with these phenomena; this proposed research will be able to identify appropriate biomarkers that indicate disturbances in synaptic AB metabolism in brains, before the development of Alzheimer's disease. Such bio-markers would be very useful in order to identify and clarify the etiology underlying the progression of AB accumulation in individual persons, and may ultimately lead to effective treatments for Alzheimer's disease. Name of organization or government: Washington University (H) Purpose of Grant or Assistance: Alzheimer's Disease Research by Kristen Funk, PhD Entitled: (A2014164F) Differential Uptake of Tau Fibrils into Neurons and Glia. Investigator's Summary: Alzheimer's disease is defined, in part, by deposits of aggregated tau protein within neurons of affected brain. Recent data have suggested that progression of AD may be due to the release of tau aggregates from afflicted neurons, followed by the uptake of tau fibrils into naive neurons, resulting in the propagation of tau pathology. To date, the role of glia in this model has remained unexplored; however, we hypothesize that promoting uptake into glia may clear tau aggregates without contributing to disease progression. Studies proposed here will establish the mechanisms of tau uptake that differ between neurons and glia with the goal to identify potential therapeutic targets that block uptake into neurons while promoting uptake into glia. Name of organization or government: Columbia University Medical Center (H) Purpose of Grant or Assistance: Alzheimer's Disease Research by Tal Nuriel, PhD Entitled: (A2014200F) Metabolomic/Lipidomic Analysis of ApoE Isoform Effects. Investigator's Summary: Carriers of the APOE e4 gene are at significantly increased risk for developing Alzheimer's disease. In order to understand the cause of this increased Alzheimer's risk, we will utilize emerging technology to measure the levels of lipids and small-molecules in mouse and human brain tissues possessing differing forms of APOE. We anticipate that the results of this study will shed new light on why carriers of the APOE e4 gene are more susceptible to Alzheimer's disease and how Alzheimer's disease can be prevented in these individuals. |

Investigator's Summary: About 70% of Alzheimer's disease risk is due to differences in DNA sequences between people. Here, we have identified how one of these DNA sequence variations changes gene expression to reduce Alzheimer's risk. The action of the DNA sequence difference is a modest 15% decrease in functional gene expression. Remarkably, an inhibitor of this gene has already been in clinical trials for leukemia, and will be tested here for its ability to act similarly to the DNA sequence variation. Name of organization or government: University of Washington School of Medicine (H) Purpose of Grant or Assistance: Alzheimer's Disease Research by Richard Morrison, PhD Entitled: (A2014237S) Bif-1 Therapy for Cognitive Impairment and Neuropathology in AD. Investigator's Summary: We have identified a protein with a unique protective function in nerve cells and this protein is lost in the brains of patients with Alzheimer's disease. The loss of this protein may make the disease worse based on studies we've done where we eliminate the protein in mice that also express symptoms of Alzheimer's disease. We would like to determine if we can improve cognitive function in patients with Alzheimer's disease by restoring the expression of this protein. We will test this possibility by developing a method to restore this protein in the nerve cells of mice that also express symptoms of Alzheimer's disease and we will determine if their cognitive abilities improve. Name of organization or government: Washington University (H) Purpose of Grant or Assistance: Alzheimer's Disease Research by David Brody, MD, PhD Entitled: (A2014270S) Purification and Characterization of Amyloid-beta Oligomers from Human Brain. Investigator's Summary: Alzheimer's disease is the most common cause of problems with memory, thinking, and behavior in older people; it is most likely caused by accumulation of a small protein called amyloid-beta. There is no cure or effective treatment for Alzheimer's disease despite decades of work, in part because our attempts so far have not focused on the most toxic forms of amyloid-beta. We have developed methods to accurately measure these toxic forms of amyloid-beta in the brains of Alzheimer's disease patients, and we now propose to purify them so that we can study them in detail. This project is vital because understanding the toxic forms of amyloid-beta will help us efficiently design effective treatments to prevent them from forming, block their toxicity, or destroy them. |
| Schedule I, Part II, Line 1, Column (H): | Name of organization or government: University of Kentucky (H) Purpose of Grant or Assistance: Alzheimer's Disease Research by M. Paul Murphy, MA, PhD Entitled: (A2014280S) A Novel Therapy for the Treatment of Dementia. Investigator's Summary: We are going to use a unique mouse model that we have developed (the db/AD mouse) to test a potential treatment for Alzheimer's disease (AD). Many cases of AD are also accompanied by large amounts of vascular pathology in the brain. The mouse we have developed has cognitive deficits reflective of the deficits seen in AD, and the db/AD mice also experience aneurysms and strokes which indicate the presence of vascular disturbances in the brain. In the hopes of improving the vascular pathology, we are going to treat these mice with a drug that is already approved for human use, and we will perform MRI imaging at regular time points to monitor any effect the drug treatment has on the vascular pathology in the brain. Name of organization or government: Washington University (H) Purpose of Grant or Assistance: Alzheimer's Disease Research by Richard Perrin, MD, PhD Entitled: (A2014296S) Novel CSF Biomarkers in Familial Alzheimer Disease. Investigator's Summary: The goal of this study is to discover a timeline of protein changes within the cerebrospinal fluid (the fluid that bathes the brain) that can be used to diagnose and monitor Alzheimer's disease (AD), even years before symptoms of the disease appear. To accomplish this goal, we will apply a powerful new technique (quantitative label-free proteomics) to measure hundreds of proteins in cerebrospinal fluid samples from people enrolled in the Dominantly Inherited Alzheimer Network (DIAN) study. Familial AD is uniquely suited to this mapping study of very early changes because the age at which symptoms begin can be reliably predicted from affected family members, and diagnosis can be definitively established by genetic testing even decades before symptoms are predicted. Such a timeline will improve the accuracy of early diagnosis, maximize the efficiency of clinical trials, and move effective treatments more quickly and cheaply from the laboratory to the pharmacy. Name of organization or government: The Ohio State University (H) Purpose of Grant or Assistance: Alzheimer's Disease Research by Chien-liang Lin, PhD Entitled: (A2014315S) Regulating Glutamate Levels as a Therapeutic Strategy for Alzheimer's Disease. Investigator's Summary: The glial glutamate transporter EAAT2 is responsible for maintaining low extracellular glutamate concentrations in our brains. Loss of EAAT2 protein and function is commonly found in patients with Alzheimer's disease. We discovered that restoration of EAAT2 function can reverse Alzheimer phenotypes in an animal model of Alzheimer's disease. The goal of this research is to develop restoration of EAAT2 function as a therapeutic strategy for Alzheimer's disease. |
| Schedule I, Part II, Line 1, Column (H): | Name of organization or government: University of Chicago (H) Purpose of Grant or Assistance: Alzheimer's Disease Research by Virginie Buggia-Prevot, PhD Entitled: (A2014316F) Role of EHD Proteins in Alzheimer's Disease Pathogenesis. Investigator's Summary: The goal of my research is to better understand the causes of Alzheimer's disease by studying the mechanisms that contribute to the disease apparition, in order to identify potential therapeutic targets. In the brain of individuals with Alzheimer's disease, a toxic peptide called amyloid is overproduced and leads to dysfunction of memory functions and ultimately the death of the nerve cells. I recently found two proteins called EHD, which are involved in amyloid peptide production in cultured neurons. The proposed investigation would determine if there is an alteration of EHD in human brains that could facilitate amyloid overproduction, and to test if amyloid overproduction could be blocked by abolishing the expression of EHD in mice that are engineered to develop Alzheimer's Disease pathology. Thus, the proposal investigates neuronal mechanisms that are intimately associated with Alzheimer's disease with the goal of establishing EHD proteins as one of the molecular players in disease pathogenesis. Name of organization or government: Northwestern University (H) Purpose of Grant or Assistance: Alzheimer's Disease Research by Jian Li, PhD Entitled: (A2014349F) Stress Response Networks in Organismal Proteostasis. Investigator's Summary: Alzheimer's disease patients are featured with aggregation of abnormally folded beta amyloid proteins in the brain that interfere with the cellular functions and eventually lead to degeneration of neurons. Stress response factors have been suggested to protect the protein toxicity associated with Alzheimer's disease. This protection could occur both in the beta amyloid expressed tissue and the neighboring tissues. Here we set out to characterize the protective mechanisms mediated by stress response pathways especially how neurons sense the toxic aggregation and how they communicate with neighboring tissues to end up an organismal protection. Name of organization or government: Washington University (H) Purpose of Grant or Assistance: Alzheimer's Disease Research by Randall Bateman, MD Entitled: (A2014384S) Stable Isotope Labeling Kinetics of Human TAU In Alzheimer's Disease. Investigator's Summary: In Alzheimer's disease Tau is increased in the brain and fluid that surrounds the brain. It is unclear why it is increased. Is this due to increased production or impaired clearance? How much is production or clearance altered? Can drugs be developed that can correct abnormal tau production or clearance? These questions can now be answered and give drugs which target tau a better chance of working in Alzheimer's disease. |

Investigator's Summary: The proposed work will determine whether degradation of the amino acid tryptophan by the enzymes TDO2 and IDO1 functions in development of Alzheimer's disease. We will use genetic and pharmacologic approaches in a mouse model of AD to identify mechanisms of action of these enzymes in early and late stages of AD development. Successful completion of these studies may lead to a novel preventive and therapeutic strategies to delay onset of AD in at-risk aging populations.

Investigator's Summary: Alzheimer's Disease is the world's most common cause of dementia and oxidative stress has emerged as a key feature and possible cause of the disease. It appears early and can accelerate progression of the disease. However, only a few treatments trying to prevent oxidative stress have provided positive results. With this project we will study a promising novel mechanism causing oxidative stress in hope to provide ideas for more efficient therapeutics. |

Investigator's Summary: A number of neurodegenerative disorders have tau deposits including Alzheimer's disease. Abnormal tau protein can cause age dependent neurodegeneration in Alzheimer's disease and related disorders. We have identified a class of drugs that prevent abnormal tau formation in animal models of disease.

Investigator's Summary: A fundamental principle of biology (and evolution) is that organisms, and cells, adapt to a stress imposed on them so that they can better handle that stress if encountered again in the future. The studies in this research project are designed to leverage this concept as a way of protecting the eye from glaucoma. In particular, we will test whether intermittently exposing mice to a hypoxic or low-oxygen stress, that by itself is not harmful; will trigger adaptive responses in the eye that make it more resistant to the damaging effects of glaucoma. If successful, these studies will confirm the presence of innate protective responses in the eye that someday could be activated in humans with glaucoma, thereby reducing the vision loss and blindness that characterizes this devastating disease. Name of organization or government: University of Wisconsin (H) Purpose of Grant or Assistance: National Glaucoma Research by Donna Peters, PhD Entitled: (G2014051) Use of Small Molecules to Control ECM Homeostasis. Investigator's Summary: A major risk factor for glaucoma is an elevation of intraocular pressure caused by the reduced movement of fluid out of the eye. This movement is restricted because the passageways that allow fluid to exit the eye are clogged with too much protein. The goals of this research are to understand how these proteins are deposited in these passageways and to identify ways to prevent the proteins from being deposited. Name of organization or government: Oregon Health and Science University (H) Purpose of Grant or Assistance: National Glaucoma Research by Janice Vranka, PhD Entitled: (G2014058) Altered Versican Fibrillar Interactions in the Outflow Pathway. Investigator's Summary: Our research focuses on the trabecular meshwork, a discrete tissue located in the eye around the base of the cornea, near the ciliary body, which is responsible for draining the aqueous humor from the eye via the anterior chamber and is believed to be the tissue that regulates intraocular pressure, a critical factor in the development of glaucoma. Our laboratory is investigating the hypothesis that a specific subset of complex molecules that reside in the trabecular meshwork, and that interact with each other, are important in the regulation of aqueous humor outflow resistance. When these processes are disrupted there will be changes in the tissue that lead to alterations in outflow facility. Thus our primary objective is aimed at improving the overall understanding of how aqueous humor outflow resistance is regulated and what are the triggers in the development of glaucoma in order to facilitate the development of novel therapies aimed at helping glaucoma patients. |

Investigator's Summary: Glaucoma is the second most common cause of blindness worldwide. Studies over the past few years have shown that blood flow and the way it changes in the diseased eye play a role. This project will look at what causes the blood flow change and this could lead to an original treatment for this disease.

Investigator's Summary: One of the major risk factors for the development of glaucoma is an increased pressure inside the eye. An increase of pressure occurs in the eye when fluid is not drained properly through the drainage structures in the front of the eye. Our project aims to understand what regulates the arrangement and construction of the drainage structures and how changes in this makeup prevent proper drainage in the eye.

Investigator's Summary: Glaucoma is related to overstimulation of certain genes/proteins in the trabecular meshwork (TM), a condition caused by reduced expression of antioxidants which results from aging or oxidative stress. We propose to examine further the underlying causes and mechanisms by which pathobiology of the TM develops, and explore novel targets for glaucoma therapy, including antioxidant therapy based on the protective protein Prdx6. |
| Schedule I, Part II, Line 1, Column (H): | Name of organization or government: Duke University Eye Center (H) Purpose of Grant or Assistance: National Glaucoma Research by Stuart McKinnon, MD, PhD Entitled: (G2014076) Neuroinflammation: the Role of Lymphocytes in Glaucoma. Investigator's Summary: In glaucoma, permanent vision loss and blindness occur when retinal ganglion cells (RGCs) that make up the optic nerve are lost. Increasing evidence points to a central role of the immune system in the death of RGCs in glaucoma. We have recently shown the surprising finding that in an experimental mouse model of glaucoma, a severely immunodeficient transgenic mouse that lacks T- and B-lymphocytes (Rag1 knockout) is robustly protected against optic nerve damage due to chronic exposure to elevated intraocular pressure (IOP). These transgenic mice lack expression of Rag1, a protein essential to the generation of mature T- and B-lymphocytes, and are thus immunodeficient. This finding generates the novel hypothesis that immune system events involving lymphocytes are necessary for RGC cell death and optic nerve axon loss in glaucoma. This project will determine whether specific populations of lymphocytes are required for RGC death in glaucoma, and to determine if blocking lymphocyte extravasation into ocular tissues (diapedesis) rescues RGCs in a mouse glaucoma model. We will isolate T- or B-cells using standard immunology techniques and transfer these cells to Rag1 knockout mice to reconstitute this portion of the mouse immune system. We will then utilize our well-established mouse glaucoma model to determine if either T- or B-cells are necessary for RGC axon loss. Lymphocytes migrate from the bloodstream to tissues by the process of diapedesis, which requires the expression of a4 integrin protein on vascular endothelium. We will induce glaucoma in transgenic mice that carry a point mutation in a4 integrin to determine if blocking lymphocyte diapedesis is neuroprotective in our mouse glaucoma model. We will also test whether pharmacological blockage of a4 integrin-mediated diapedesis with a murine version of natalizumab (Tysabri, Biogen, Inc.) is neuroprotective in our mouse glaucoma model. If T- or B-cells are necessary for glaucoma damage, further research will be designed to determine whether specific lymphocyte subpopulations (e.g. CD4+, CD8+, etc.) can be identified as crucial to RGC axon loss in glaucoma. Given the existing literature, data supporting or refuting the roles of lymphocytes in glaucomatous RGC death would represent a significant advance for the field and therapies can be designed to modulate the immune system and prevent vision loss and blindness in our human glaucoma patients. Name of organization or government: University of Pittsburgh (H) Purpose of Grant or Assistance: National Glaucoma Research by Yiqin Du, MD, PhD Entitled: (G2014086) A Mouse Glaucoma Model and Stem Cell-Based Therapy for Glaucoma. Investigator's Summary: Glaucoma is a leading cause of irreversible blindness; elevated intraocular pressure is a major risk factor and it is controllable. The trabecular meshwork acts as a drainage system to the eye, and blockage of this drainage, such as by irregularities in the cells and matrix of the meshwork, can lead to a build-up of aqueous fluid in the eye and subsequent elevation of intraocular pressure. We have isolated and characterized immature stem cells from the trabecular meshwork with the ability to seek out and repair the damage in this tissue. This project will identify a drug enabling us to model elevated pressure by damaging trabecular meshwork in a mouse, then to apply trabecular meshwork stem cells with the purpose of restoring a functioning meshwork and reducing the intraocular pressure.

Investigator's Summary: Glaucoma is an eye disease that can lead to blindness. We propose a new model to detect glaucoma changes over time. This model will be tailored for each patient and tested in a different group of patients. We will use this model to predict which patients are likely to change over time. |

Investigator's Summary: To understand the causes and effects of glaucoma, researchers often rely on animal models in which eye pressure is elevated by experimental means. Traditional methods of elevating pressure can reproduce key features of the disease, but they are limited by finite success rates, sporadic pressure information, and variable exposure histories. These limitations hamper research progress and may prevent major breakthroughs. The overarching goal of this project to develop a smart pump that would for the first time gives glaucoma researchers and clinicians unprecedented control over eye pressure.

Investigator's Summary: Pigment dispersion syndrome (PDS) causes pigmentary glaucoma which is a common form of open-angle glaucoma that usually affects young adults and can be inherited. No genes responsible for this condition have been identified so far in humans. In this proposal, we will use whole exome sequencing, a new and powerful technology to find genes that can cause this common form of glaucoma. The results from this project can be used to develop new methods of diagnosis and treatment for PDS and pigmentary glaucoma.

Investigator's Summary: Nerve cells called retinal ganglion cells from the connection between the eye and the brain. In glaucoma, these nerve cells die and vision is permanently lost. We have previously shown that a protein called dual leucine zipper kinase (DLK) is critical for the death of these cells. Thus, this proposal seeks to identify a drug that might block interfere with DLK and prevent retinal ganglion cell death. |

Investigator's Summary: Progression of age-related macular degeneration (AMD) coincides with structural changes to the eye. Currently, clinicians and researches use visible light and histological sectioning to study these changes, but are limited to detections of only fairly large structures and lack necessary information associated with the disease. We propose a new paradigm in light microscopy to detect both structures changes and functional abnormalities associated with AMD. Currently, this detection method is unknown and unavailable to researchers and clinicians. We propose to investigate the viability of this technique for studying AMD.

Investigator's Summary: In aging patients with central vision loss, a group of cells in the back of the eye, retinal pigment epithelia (RPE) is specifically injured. The aim of this study is to examine whether RPE injury arises from sustained, irreparable damage to the cell's protein factories. We predict that patients with changes to a protein called HtrA1 are particularly prone to such damages. We propose that rectifying RPE injury with "chemical chaperones" can benefit these patients, and that this class of drugs can be used as a strategy to manage central vision loss.

Investigator's Summary: Age-related macular degeneration (AMD) is the leading cause of vision loss in the elderly. More than 11 million Americans are affected by AMD with no effective treatments available. Autophagy is a self-eating process in the cells that involves degradation of unwanted cellular components to supply the cell with energy when needed. Failure in autophagy is related to diseases. We propose to study the role of autophagy and its possible dysfunction in AMD. |

Investigator's Summary: Few organisms have a more detailed visual experience than humans. The reason is that we possess a specialization of our retina, called the fovea, that constitutes an extraordinarily "high definition" pixel array. Macular degeneration is a leading cause of blindness that devastates vision by attacking the fovea. By investigating how the fovea works, we will help the diagnosis, prevention, and treatment of macular degeneration, while also gaining insight into how our power of sight outstrips that of most other creatures.

Investigator's Summary: Age-related macular degeneration (AMD) is a devastating eye disease that affects a large percentage of the American population. Although we don't have a cure or a good way to restore vision in individuals affected by the disease, there are ways to prevent further vision loss for patients that are suffering from AMD. Our approach is to extract the stem cells from a patient's tooth and turn them into an important eye cell that we can then transplant back into the patient's eye. In order to transplant these eye cells, we need the cells to remain intact and will be using silk as a natural product that the body won't reject to deliver these eye cells. Name of organization or government: University of California, San Francisco (H) Purpose of Grant or Assistance: Macular Degeneration Research by Sara Venters, PhD Entitled: (M2014060) Establishing the Foveal Retina During Embryonic Development. Investigator's Summary: The central retina is the small portion of the eye used for our clearest and sharpest vision. Anatomically, it is different from the rest of the eye, and we do not understand exactly why. The central retina is specifically affected in several eye diseases, and trying to understand how exactly it differs can help with treatment and future therapies for re-growing this portion. In this proposal we will first follow the development of the precursors to the central retina, and next we will determine which, if any, of the environments that they pass through during development is important for making them specifically central retina. |

Investigator's Summary: One aspect of the damage to the retina that occurs in age-related macular degeneration (AMD), a disease responsible for visual handicap in millions of elderly people, is caused by the presence of low grade inflammation over long periods of time. Specialized cells in the retina express a class of cell-surface proteins that are known to play a role in opposing inflammatory responses in other tissues of the body. The purpose of the proposed studies is to determine the role of these proteins in decreasing inflammatory responses in the retina. The outcome of these studies will lead to increased understanding of the control inflammation in the retina, and the possibilities for developing novel therapies aimed at regulating this mechanism.

Investigator's Summary: Age related macular degeneration (AMD) is easily becoming the number one cause of blindness in the world today. A major problem in finding a cure is not knowing what causes the disease and having a good model system to test a therapy. In this study, we utilize a novel genetic model that recapitulates the blood vessel defect seen in AMD patients and thus have a powerful tool to identify a factor that can cause this disease outcome, understand the disease process, and a model to test therapies. Name of organization or government: University of Maryland, Baltimore (H) Purpose of Grant or Assistance: Macular Degeneration Research by Richard Thompson, PhD Entitled: (M2014085) Role of Zn and HAP in Inducing Sub-RPE Deposits and Age-related Macular Degeneration. Investigator's Summary: We have discovered what appears to be an early step in the process of developing deposits (drusen) in the aging retina, which can lead to macular degeneration (AMD). We believe that zinc and inflammation are involved, and have developed a method for visualizing when the step has occurred in the intact eye. The thrust of our project is to see how zinc and inflammation are involved in this step and how early and broadly the step may occur in ordinary eyes: does the step happen at 40 years of age, at 60 years of age, and does it occur in everybody? We anticipate our visualization method may be usable as a screening test for AMD (patent pending), and our improved understanding of how AMD develops may lead to new, early treatments. |

Investigator's Summary: Current knowledge suggests that the development of age-related macular degeneration (AMD), a blinding disease that affects many older individuals, may involve the abnormally high build-up of a protein known as "amyloid-beta" in the eye. If abnormally high amyloid-beta indeed promotes AMD, removing this excessive amyloid-beta could be a therapy for AMD. It is known that a type of enzyme termed "peptidase" can break down amyloid-beta. Accordingly, using mice with AMD-like disease as our experimental system, we propose to study whether artificially increasing the amount of peptidase in the eye can slow or block the progress of the disease.

Investigator's Summary: Our research is trying to understand what causes the severe form of wet macular degeneration, a common disease of the back of the eye (retina) and one of the leading causes of blindness in the United States. Macrophages are cells in the body that fight off infection, but in some cases, can cause damage to tissues in the body. We are trying to determine how macrophages make wet macular degeneration worse and harder to treat with available medicines. If we can understand how macrophages make this disease worse, we hope that we can develop new medicines to treat patients with the disease who continue to lose vision.

Investigator's Summary: The Retinal Pigmented Epithelium (RPE) is a single layer of pigmented cells situated between the neurosensory retina and the choroid, the vascular layer at the back of the eye. The RPE is involved in the phagocytosis of photoreceptor outer segments (OS), a role essential for the maintenance and survival of the photoreceptors (light sensitive cells) as well as autophagy (self digestion by a cell), and may be of particular importance because of the very high metabolic activity of RPE. We have generated a RPE-specific Cryba1 gene knockout mouse, which will serve as a genetic tool to better understand the processes of phagocytosis and autophagy in RPE. Our studies may lead to development of therapeutic targets in the future for some manifestations of AMD that result from defective phagocytosis and/or autophagy in RPE. |

Investigator's Summary: Age-related macular degeneration (AMD) is the most common cause of irreversible blindness in the elderly and is caused by a local inflammatory response affecting the function of the retinal pigment epithelium and the photoreceptors. In a mouse model of AMD we could show that inhibiting a molecular complex that is important for propagating this inflammatory response, the inflammasome, reduces pathologies of AMD in this model. Thus, we propose that mechanisms that inhibit the inflammasome are likely to reduce AMD progression in patients as well. Here, we will test mechanisms that control inflammasome activation in a mouse model of AMD to identify potential novel treatment approaches for AMD.

Investigator's Summary: Macular degeneration is a progressive eye condition affecting as many as 15 million Americans. The disease attacks the macula of the eye, where our sharpest central vision occurs, affecting reading, driving, identifying faces, watching television, safely navigating stairs and performing other daily tasks. The retinal pigment epithelium and choriocapillaris, the blood vessels that provide nutrition to the outer retina, die in age-related macular degeneration (AMD). This study will document the inflammatory cells under retina that may contribute to this death if activated. Drugs already exist to control their activation so this study could suggest new therapies for AMD. Name of organization or government: Stanford University (H) Purpose of Grant or Assistance: Macular Degeneration Research by Douglas Vollrath, MD, PhD Entitled: (M2014137) Genetics of RPE Metabolism: Implications for Age-related Macular Degeneration. Investigator's Summary: The nerves that sense light in the eye and the cells of the retinal pigment epithelium (RPE) form a critical partnership necessary for vision. We seek to understand how the capability of RPE cells to get energy from food molecules varies among human individuals due to differences in their genes and how RPE cells control this process. Success of this project may help us to better understand why macular degeneration affects some people more than others, eventually leading to improved treatment for this disease. |
