Mediation of central prostaglandin effects by serotoninergic neurons

Abstract
Ten days after administration of 5,6-dihydroxytryptamine, which causes degeneration of central serotoninergic neurons, the depressive behavioral effects of PGF and PGE2 were evidently inhibited. Central chemical serotoninectomy abolished the hyperthermic and hypertensive effects of PGF, but only slightly affected those of PGE2. It is concluded that serotoninergic neurons mediate the depressive behavioral action of both PGF and PGE2. They also mediate the hyperthermic and hypertensive action of PGF but not of PGE2. This suggests that these prostaglandins have different central modes of action.
