摘要：

Both human and rabbit brain contain the 5-hydroxytryptamine (5-HT)(1D) subtype of 5-HT1 receptors, We studied the effects of 5-HT1D receptor stimulation on neocortical [H-3]gamma-aminobutyric acid (GABA) release from GABAergic neurons in these species. The 5-HT1D receptor agonist sumatriptan depressed [H-3]GABA release in human neocortex and the 5-HT1 receptor antagonist metitepin prevented this depression with potencies suggesting mediation by 5-HT1D-like receptors. In rabbit neocortex, however, 5-HT1D agonists did not affect the release of [H-3]GABA. Since 5-HT and GABA seem to function antagonistically in anxiety disorders their neocortical interaction may be (patho)physiologically relevant.
