Modulation of vascular function by perivascular adipose tissue: the role of endothelium and hydrogen peroxide

Abstract

PVAT exerts its anti-contractile effects through two distinct mechanisms: (1) by releasing a transferable relaxing factor which induces endothelium-dependent relaxation through NO release and subsequent K(Ca) channel activation, and (2) by an endothelium-independent mechanism involving H2O2 and subsequent activation of sGC.
