Cone functional loss is the key event leading to blindness in rod-cone dystrophies. Dr. Sahel's lab embarked on a "fishing expedition" aimed at identifying the mechanisms underlying this loss, turning up potential clues for therapies aiming at preserving/restoring light-adapted and central vision in these patients. With collaborators Thierry Leveillard and Saddek Mohand-Said, Dr. Sahel discovered Rod-derived Cone Viability Factor, identified its receptor, and demonstrated its potential therapeutic benefit in several animal models, paving the way to upcoming clinical trials. This strategy has been extended to attempt to restore cone or inner retinal function by optogenetics. In depth phenotyping will guide the selection of target populations of patients that might benefit from these strategies; the development of novel, real life, functional outcome measurements will be needed to demonstrate its therapeutic value.
Dr. José-Alain Sahel, MD, PhD, is Professor and Chairman of the Department of Ophthalmology at the University of Pittsburgh Medical Center. He holds The Eye and Ear Foundation Endowed Chair of Ophthalmology in the University of Pittsburgh Medical School. Dr. Sahel is also the Director of Institut de la Vision at the Pierre et Marie Curie Medical School, Sorbonne Universites/Inserm/CNRS, Centre Hospitalier National d'Ophtalmologie, Paris.
8th Annual McPherson ERI Vision Science Poster Session Draws a Crowd
The McPherson ERI's annual poster session, held on Tuesday, October 4th in the atrium of the School of Medicine and Public Health, attracted close to 100 McPherson ERI members and affiliated researchers. 37 MERI members, including many trainee members, displayed their current research in a wide range of vision science fields. Professor JoAnn Kuchera-Morin, Director and Chief Scientist of the AlloSphere Research Facility and Professor of Media Arts & Technology and of Music at the University of California, Santa Barbara, gave the annual McPherson ERI Lecture...Read more
The Proceedings of the National Academy of Sciences has published a new paper by Li Xuan Tan, Kimberly Toops, and Aparna Lakkaraju which pinpoints how immune abnormalities in the retinal pigment epithelium can cause macular degeneration. The paper also notes that drugs commonly used to treat depression can counteract these abnormalities and protect the retina. Read more....
