WebJun 4, 2016 · Ca 2+ fluxes into the cytosol, which are passive (downhill), are mediated by Ca 2+ channels, whereas relaxation is an active (uphill) process that occurs when ion pumps … 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
