High-fat diet promotes adrenaline production by visceral adipocytes

Purpose Catecholamines (CA) play a major role in metabolism and immune response. Recent reports showing adipose tissue can synthetize CA enlighten new roles for these amines in obesity. This study aimed to evaluate the expression of both tyrosine hydroxylase (TH) and phenylethanolamine N-methyltransferase (PNMT) and CA content along preadipocytes differentiation, under normal and obesigenic conditions.
