G-protein activation at 5-HT1A receptors by the 5-ht1F ligand LY334370 in guinea-pig brain sections and recombinant cell lines.

1. G-protein activation by the 5-ht1F receptor agonist 5-(4-fluorobenzoyl)amino-3-(1-methylpiperidin-4-yl)-1H-indole fumarate (LY334370) was investigated by use of autoradiography of receptor-activated G-proteins in guinea-pig brain sections and [35S]-GTPgammaS binding responses in cell lines stably expressing human 5-HT1A (h 5-HT1A) receptors. 2. LY334370… CONTINUE READING
