Effect of membrane potential level on serotonin-induced smooth muscle contractions of the rabbit pulmonary artery

Abstract

Serotonin-induced contraction of vascular smooth muscles is activated chiefly by calcium entering the cell from the extracellular medium [1-4]. The entry of Ca ions into smooth-muscle cells (SMC) is effected through calcium channels controlled either by the transmembrane potential or by receptors [5, 6, 9, 12, 13]. Activity of receptor-controlled calcium… (More)
