Lipolytic effects of beta1, beta2 and beta3-adrenergic agonists in isolated human fat cells from omental and retroperitoneal adipose tissues.
The presence of beta1- and beta2-adrenoceptors has been clearly established in human fat cells. There is some controversy about the presence and function of beta3-adrenoceptors. It is well established that there are marked regional variations in catecholamine-induced lipolysis. In this work the possibility that a beta3-adrenoceptor plays a significant role in the control of lipid mobilization is studied and also its importance in comparison to beta1- and beta2-adrenoceptors in isolated human fat cells, is evaluated, by measuring the in vitro lipolysis induced by dobutamine, salbutamol, metaproterenol, BRL 37344 and CGP 12177A. Human adipocytes from omental and retroperitoneal fat deposits exhibited an "atypical" beta-adrenergic response but, given the small lipolytic effect initiated by BRL 37344 and CGP 12177A, they are probably poorly equipped in functional beta3-adrenoceptors.
