...John Sebastiani; Allyson Sabatelli; M. Danielle McDonald ABSTRACT Plasma serotonin (5-hydroxytryptamine, 5-HT) homeostasis is maintained through the combined processes of uptake (via the 5-HT transporter SERT, and others), degradation (via monoamine oxidase, MAO) and excretion. Previous studies...
