Population
Descending vasa recta (DVR) pericytes
Comparison

Suggests ANG II depolarizes DVR pericytes partly via K+ inhibition; hypothesis-generating for medullary perfusion control, no clinical translation yet.
Does ANG II inhibit K+ conductance in descending vasa recta pericytes?
ANG II depolarizes descending vasa recta pericytes through simultaneous activation of Cl- channels and inhibition of K+ channels.
