摘要：

We report here that angiotensin II (AII) and the AT2 receptor-selective ligand, CGP 42112, modulate the T-type calcium current in non-differentiated NG108-15 cells, which express only AT2 receptors. Both peptides decrease the T-type calcium current at membrane potentials above -40 mV and shift the current voltage curve at lower potentials with maximal effect between 5 and 10 min after application. These data describe a new cellular response to AII and suggest that the AT2 receptor mediates certain neurophysiological actions of this hormone.
