Serotonin (5-hydroxytryptamine, 5-HT)(1A) receptor agonism and 5-HT(2A) receptor antagonism are components in the action of some of the recently developed antipsychotic drugs, e.g., clozapine and ziprasidone. However, studies of the role of 5-HT(1A) receptor agonism in the ability of these...

(-)-Pindolol (2.5-20.0 mg/kg, s.c.) markedly increased extracellular levels of dopamine (DA) and noradrenaline (NA) in single dialysate samples of the frontal cortex (FCX) of freely-moving rats. This action was specific inasmuch as serotonin (5-HT) levels were not significantly modified. In...

The nodose ganglion contains the cell bodies of afferent nerves which convey predominantly sensory information from the viscera to the central nervous system (CNS). Autoradiographic studies show binding sites for beta-adrenoceptor ligands are present on sections of the rat nodose...

The Journal of pharmacology and experimental therapeutics, 291(1), 229-238 (1999-09-22)
Clinical studies have shown that pindolol can enhance the effects of antidepressant drugs, presumably by acting as an antagonist at somatodendritic 5-hydroxytryptamine (5-HT)(1A) autoreceptors, which regulate the firing rate of central serotonergic neurons. The current study characterized the action of...

The identification of self-renewing and multipotent neural stem cells (NSCs) in the mammalian brain holds promise for the treatment of neurological diseases and has yielded new insight into brain cancer. However, the complete repertoire of signaling pathways that governs the...
