Advanced glycation end product (AGE)-their receptor (RAGE) and angiotensin II (AII) are implicated in diabetic retinopathy. However, a crosstalk between the two is not fully understood. In vivo, AGE injection stimulated RAGE expression in the eye of spontaneously hypertensive rats, which was blocked by an AII-type 1 receptor blocker, telmisartan. In vitro, AII-type 1 receptor-mediated reactive oxygen species generation elicited RAGE gene expression in pericytes through NF-κB activation. Further, AII augmented AGE-induced pericyte apoptosis, the earliest hallmark of diabetic retinopathy. Our present study may implicate a crosstalk between AGE-RAGE system and AII in diabetic retinopathy.
