Increased expression of CD200 on circulating CD11b+ monocytes in patients with neovascular age-related macular degeneration
OBJECTIVE: Dysregulation of retinal microglial activity has been implicated in the pathogenesis of neovascular age-related macular degeneration. Microglia activity can be regulated through the membrane protein CD200 and its corresponding receptor, the CD200 receptor (CD200R). Because both the ligand and the receptor are expressed on a broad spectrum of cell types, we set out to study the expressio
