Enhanced serotonin response in the hippocampus of Galphaz protein knock-out mice
The serotonin-1A [5-hydroxytryptamine 1A (5HT1A)] receptor is important for emotional and homeostatic processes in the central nervous system. In the hippocampus, the 5HT1A receptor couples to inhibitory Gi/o proteins to decrease pyramidal cell excitability. Here we investigate the 5HT1A receptor in a mouse deficient in the α-subunit of Gz protein (Gαz knock-out). Behavioural tests showed heightened anxiety and depression-like behaviour in the Gαz knock-out mice. Whole-cell recording in CA1...[Show more]
