1 OBJECTIVES: To examine the effects of increases in serotonin following the administration of the serotonin precursor 5-hydroxy-L-tryptophan (5-HTP) in SERT wild-type (+/+), heterozygous (+/-), and -/- mice. 5-Hydroxytryptophan solute carrier family 6 (neurotransmitter transporter, serotonin), member 4 Mus musculus
2 OBJECTIVES: To examine the effects of increases in serotonin following the administration of the serotonin precursor 5-hydroxy-L-tryptophan (5-HTP) in SERT wild-type (+/+), heterozygous (+/-), and -/- mice. 5-Hydroxytryptophan solute carrier family 6 (neurotransmitter transporter, serotonin), member 4 Mus musculus
3 Behaviorally, 5-HTP induced exaggerated serotonin syndrome behaviors in SERT-/-, mice with similar effects in male and female mice. 5-Hydroxytryptophan solute carrier family 6 (neurotransmitter transporter, serotonin), member 4 Mus musculus
4 Physiologically, 5-HTP induced exaggerated temperature effects in SERT-deficient mice. 5-Hydroxytryptophan solute carrier family 6 (neurotransmitter transporter, serotonin), member 4 Mus musculus
5 The 5-HT1A antagonist WAY 100635 decreased 5-HTP-induced hypothermia in SERT+/+ and +/- mice with no effect in SERT-/- mice, whereas the 5-HT7 antagonist SB 269970 decreased this exaggerated response in SERT-/- mice only. 5-Hydroxytryptophan solute carrier family 6 (neurotransmitter transporter, serotonin), member 4 Mus musculus
