Diabetic nephropathy is the leading cause of chronic kidney disease in the United States, and one of the most significant long-term complications of both type 1 and type 2 diabetes, which currently lack fully effective therapy. Hyperglycemia and activation of the renin-angiotensin system (RAS) are thought to be the two main drivers of this pathology. We have recently shown that selective blockade of peripheral cannabinoid receptor-1 (CB1R) delayed and attenuated the development of type 2 diabetes in a rat model. Here we show that the nephropathy-inducing effects of both hyperglycemia and activation of the RAS involve CB1R activation in glomerular podocytes, and that antagonism of peripheral CB1R could represent a novel, effective, and rational approach to both prevent and reverse diabetic nephropathy.
