Abstract

Rats were tested for dipsogenic and pressor responses to intracerebroventricularly (icv) administered Ang II and for dipsogenic responses to icv administered carbachol in the absence and presence of pertussis toxin, also administered icv. Pertussis toxin did not inhibit the pressor or dipsogenic responses to Ang II, but did inhibit the dipsogenic responses to carbachol. This suggests that the pressor and dipsogenic responses to Ang II in the brain are not mediated by a pertussis toxin-sensitive G protein, but that the muscarinic cholinergic dipsogenic response is mediated by a pertussis toxin-sensitive G protein.
