Scientists working at the Research Center on Aging at the Health and Social Services Centre — University Institute of Geriatrics of Sherbrooke (CSSS-IUGS) have been studying strategies for protecting retinal pigment epithelium (RPE) cells. Dysfunction of the RPE is found in retinopathy and age-related macular degeneration, which is the leading cause of blindness of elderly people in developed countries. Findings published today in the Canadian Journal of Physiology and Pharmacology...

In a study published on line this week in the journal Human Molecular Genetics, Drs. Donita Garland, Rosario Fernandez-Godino, and Eric Pierce of the Ocular Genomics Institute at the Massachusetts Eye and Ear, Harvard Medical School, along with their colleagues, reported the unexpected finding that in mice genetically engineered to have an inherited form of macular degeneration, turning off the animals' complement system, a part of the immune system, prevented the disease. Macular...

University of Kentucky researchers, led by Dr. Jayakrishna Ambati, have made an exciting finding in the "dry" form of age-related macular degeneration known as geographic atrophy (GA). GA is an untreatable condition that causes blindness in millions of individuals due to death of retinal pigmented epithelial cells. The paper, "ERK1/2 Activation is a Therapeutic Target in Age-Related Macular Degeneration" appears in the current online issue of the premier journal Proceedings of the National...

Grapes May Help Prevent Age-related Blindness

Study shows grapes provided more antioxidant protection for eyes than lutein Can eating grapes slow or help prevent the onset of age-related macular degeneration (AMD), a debilitating condition affecting millions of elderly people worldwide? Results from a new study published in Free Radical Biology and Medicine suggest this might be the case. The antioxidant actions of grapes are believed to be responsible for these protective effects. The study compared the impact of an...

Short interfering RNAs induce retinal degeneration via TLR3 and IRF3 According to new research by University of Kentucky investigators, an emerging pharmaceutical platform used in treating a variety of diseases may produce unintended and undesirable effects on eye function. The paper, "Short-interfering RNAs Induce Retinal Degeneration via TLR3 and IRF3", appears in the current online edition of the journal Molecular Therapy, a publication of the Nature Publishing Group and the American...

The notion of transplanting adult stem cells to treat or even cure age-related macular degeneration has taken a significant step toward becoming a reality. In a study published today in Stem Cells, Georgetown University Medical Center researchers have demonstrated, for the first time, the ability to create retinal cells derived from human-induced pluripotent stem cells that mimic the eye cells that die and cause loss of sight. Age-related macular degeneration (AMD) is a leading cause of...
