NIH study suggests immune system could play a central role in AMD
Date:11/28/2012

ntrol subjects without the disease. These studies also found increased IL17RC levels in circulating blood and, most importantly, in the retina of patients with AMD but not controls.

Based on these results, the authors propose that chronic increased levels of the IL17RC protein in the retina likely promote inflammation and recruitment of immune cells that damage the retina and lead to AMD.

"This study strongly implicates epigenetic DNA methylation as another crucial biological pathway for understanding the molecular basis of AMD," according to Nussenblatt.

The investigators next plan to evaluate what environmental factors may be responsible for the regulation of IL17RC and how the epigenetic regulation leading to the chronic inflammation in AMD patients can be reversed by novel therapies. They will also evaluate the role of epigenetics in other eye diseases.
