Abstract
Monocyte chemoattractant protein-1(MCP-1) is a cytokine which belongs to the CC chemokine family. Retinal pigment epithelium (RPE) cells, photoreceptors and microglial cells in the retina can secrete MCP-1. Physiological level of MCP-1 is important for preserving morphology of RPE and glial cells, as well as retinal function and gross morphology. MCP-1 is likely released from Muller glia and the RPE cells when retina under stress, and attracts microglia/macrophages to the sites of retinal damage, activates the microglia to ingest cell debris. MCP-1 has been found upregulated in the intraocular fluid of retina in patients and animal models with retinal detachment, posterior uveitis and age-related macular degeneration. The expression of MCP-1 may be response to retinal inflammation. Therefore, it is tempting to speculate that pharmacological targeting of MCP-1 may be a safe and viable strategy in treatment of retinal disease.
