Diabetic retinopathy is a chronic low-grade inflammatory disease; however, the mechanisms remain elusive. In the present study, we demonstrated that endoplasmic reticulum (ER) stress was activated in the retina in animal models of diabetes and oxygen-induced retinopathy (OIR). Induction of ER stress by tunicamycin resulted in significantly increased expression of inflammatory molecules in the retina. Inhibition of ER stress by chemical chaperone 4-phenyl butyric acid ameliorated inflammation in cultured human retinal endothelial cells exposed to hypoxia, and in the retinas of diabetic and OIR mice. These findings indicate that ER stress is a potential mediator of retinal inflammation in diabetic retinopathy.
