'Protein S' Essential for Retina Health

Researchers at the Hebrew University of Jerusalem, in collaboration with researchers at the Salk Institute in California, have found for the first time that a specific protein is essential not only for maintaining a healthy retina in the eye, but also may have implications for understanding and possibly treating other conditions in the immune, reproductive, vascular and nervous systems, as well as in various cancers,” according to Science Daily. “Their work, reported online in the journal Neuron, highlights the role of Protein S in the maintenance of a healthy retina through its involvement in the process of pruning photoreceptors, the light-sensitive neurons in the eye. (This process is also referred to as phagocytosis.) These photoreceptors keep growing and elongating from their inner end. In order to maintain a constant length, they must be pruned from their outer end by specialized cells called retinal pigment epithelial cells.” Read more.
