Two types of cardiac myocytes
WebIn cardiac muscle, 2 types of Ca 2+ channels, the L- (low threshold type) and T-type (transient-type), transport Ca 2+ into the cells. The L-type channel is found in all cardiac cell types. The T-type channel is found principally in … WebMay 2, 2003 · Abstract. Fatty acids are a major source of energy for cardiac myocytes. Changes in fatty acid metabolism have been implicated as causal in diabetes and cardiac disease. The mechanism by which long chain fatty acids (LCFAs) enter cardiac myocytes is not well understood but appears to occur predominantly by protein-mediated transport.

Webreceptors action in cardiac myocytes, with phosphodiesterases (PDEs) playing a major role in this process by preventing cAMP diffusion. We have tested this hypothesis in adult rat ventricular myocytes (ARVMs) by characterizing PDEs involved in the regulation of cAMP signals and L-type Ca
