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.
Ambati and colleagues found evidence that activity of the inflammasome, IL-18, and MyD88 were all increased in human eyes with GA. They then showed that blocking any of these components could prevent retinal degeneration in multiple disease models. The researchers are excited that blocking these pathways could herald a new potential therapy for GA, for which there is no approved treatment.
