Adiponectin receptor 2 deficiency results in reduced atherosclerosis in the brachiocephalic artery in apolipoprotein E deficient mice.

ABSTRACT: Adiponectin has been shown to have beneficial cardiovascular effects and to signal through the adiponectin receptors, AdipoR1 and AdipoR2. The original aim of this study was to investigate the effect of combined AdipoR1 and AdipoR2 deficiency (AdipoR1(-/-)AdipoR2(-/-)) on atherosclerosis. However, we made the interesting observation that AdipoR1(-/-) AdipoR2(-/-) leads to embryonic lethality demonstrating the critical importance of the adiponectin signalling system during development. We then investigated the effect of AdipoR2-ablation on the progression of atherosclerosis in apolipoprotein E deficient (ApoE(-/-)) mice. AdipoR2(-/-)ApoE(-/-) mice fed an atherogenic diet had decreased plaque area in the brachiocephalic artery compared with AdipoR2(+/+) ApoE(-/-) littermate controls as visua
