Bk channel angiotensin
WebMay 29, 2024 · The BK channel, one of the most important potassium channels in CASMCs, plays an important role in regulating the vascular tone of the coronary artery. It has been reported that the BK channel currents account for about 65% of the total potassium channel currents in rat CASMCs. WebApr 7, 2024 · BK is a potent vasodilating kinin, metabolized by kininase-1 and kininase-2, the latter is also called angiotensin-converting enzyme (ACE) [ 38 ], meaning that the ACE inhibitory drugs (angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs)) elevate plasma kinin levels.
