Abstract
Guanosine 5â²-(γ-[35S]thio)triphosphate basal binding in nucleus basalis of Meynert and thalamic nuclei was increased in the vehicle treated group. This effect was reverted by galanin treatment and indicates that the surgery increased receptor functional coupling to G proteins, which is restored by a possible neurotrophic action mediated by galanin. In addition, in galanin administered animals, galanin-stimulated binding was increased in the amygdala but decreased in the diagonal band, whilst binding stimulation mediated by carbachol was found to be increased in the amygdala, thalamic nuclei and diagonal band. These findings indicate that galanin treatment modulates the coupling of galanin and muscarinic cholinergic receptors to G proteins in specific regions of the rat central nervous system.
