Abstract

In the present patch-clamp study we have, for the first time, shown the tissue distribution of a recently characterized cGMP-dependent Ca2+-activated Cl conductance [18] in smooth muscle cells freshly isolated from different regions: aorta, pulmonary artery, tail artery, femoral artery, femoral vein, middle cerebral artery, renal artery, portal vein, superior mesenteric artery, mesenteric small artery and colon. The cGMP-dependent Cl conductance has properties distinct from those of the ‘classical’ Ca2+-activated Cl conductances; their different sensitivities to niflumic acid and zinc were here utilized to distinguish them. They were found to be co-expressed in different patterns in smooth muscle cells of different origins. The cGMP-dependent conductance was greater in myocytes from cerebral artery and femoral vein and was greater in the renal artery, aorta, mesenteric small artery, femoral artery and the superior mesenteric artery. The presence of the cGMP-dependent Ca2+-activated Cl current in smooth muscle cells isolated from the colon demonstrates that this conductance is not limited to the vasculature. The ‘classical’ Ca2+-activated Cl conductance was strongly expressed in smooth muscle cells from the portal vein and the tail artery, and noticeably higher in the pulmonary artery.
