title: Galanin selectively modulates 5-hydroxytryptamine 1A receptors in the rat ventral limbic cortex.
abstract: The effects of galanin (10 nM) in vitro were analyzed on the binding characteristics of 5-hydroxytryptamine (5-HT) receptor subtypes in the ventral limbic cortex of the rat. It was found that galanin markedly decreased the Kd value of 5-HT1A binding, while there were no effects on the binding characteristics of the 5-HT1B or 5-HT2 radioligands. These results indicate that the existence of a selective intramembrane interaction between galanin receptors and 5-HT1A receptors in the rat ventral limbic cortex.
