Kojima T, Matsumoto M, Togashi H, Tachibana K, Kemmotsu O, Yoshioka M: Fluvoxamine suppresses the long-term potentiation in the hippocampal CA1 field of anesthetized rats: an effect mediated via 5-HT1A receptors. Brain Res. 2003 Jan 3;959(1):165-8.
A selective 5-HT reuptake inhibitor, fluvoxamine (10 and 30 mg/kg, i.p.) suppressed long-term potentiation (LTP) in the hippocampal CA1 field of anesthetized rats. Fluvoxamine (30 mg/kg, i.p.)-induced suppression of LTP was completely reversed by the 5-HT (1A) receptor antagonist NAN-190 (0.5 mg/kg, i.p), but not by the 5-HT (4) receptor antagonist GR 113808 (20 microg/rat, i.c.v.) and the 5-HT (7) receptor antagonist DR 4004 (10 microg/rat, i.c.v.). These data suggest that the inhibitory effect of fluvoxamine on LTP induction is mediated via 5-HT (1A) receptors. |
