Vasa recta pericytes express a strong inward rectifier K+ conductance
2006
American Journal of Physiology. Regulatory Integrative and Comparative Physiology
Strong inward rectifier potassium channels are expressed by some vascular smooth muscle cells and facilitate K ϩ -induced hyperpolarization. Using whole cell patch clamp of isolated descending vasa recta (DVR), we tested whether strong inward rectifier K ϩ currents are present in smooth muscle and pericytes. Increasing extracellular K ϩ from 5 to 50 and 140 mmol/l induced inward rectifying currents. Those currents were Ba 2ϩ sensitive and reversed at the K ϩ equilibrium potential imposed by the
