The serotonin transporter (SERT or 5-HTT) also known as the sodium-dependent serotonin transporter and solute carrier family 6 member 4 is a protein that in humans is encoded by the SLC6A4 gene. [5] SERT is a type of monoamine transporter protein that transports the neurotransmitter serotonin from the synaptic cleft back to the presynaptic ...
Selective serotonin reuptake inhibitors (SSRIs) selectively inhibit the reuptake of serotonin and are a widely used group of antidepressants. [31] With increased receptor selectivity compared to TCAs, undesired effects such as poor tolerability are avoided. [29] Serotonin is synthesized from an amino acid called L-tryptophan.
Serotonin (/ ˌ s ɛr ə ˈ t oʊ n ɪ n, ˌ s ɪər ə-/) [6] [7] [8] or 5-hydroxytryptamine (5-HT) is a monoamine neurotransmitter.Its biological function is complex, touching on diverse functions including mood, cognition, reward, learning, memory, and numerous physiological processes such as vomiting and vasoconstriction.
First, serotonin system dysfunction cannot be the sole cause of depression, because not all patients treated with antidepressants show improvement, despite the fact that most patients still show a rapid increase in synaptic serotonin. Second, if significant mood improvements do occur, this is often not for at least two to four weeks.
[11] [12] Hoping to find a derivative inhibiting only serotonin reuptake, another Eli Lilly scientist, David T. Wong, proposed to retest the series for the in vitro reuptake of serotonin, norepinephrine and dopamine, using a technique developed by neuroscientist Solomon Snyder. [10]

In addition, the augmentation of a selective serotonin reuptake inhibitor (SSRI) or serotonin-norepinephrine reuptake inhibitor with lisdexamfetamine, a norepinephrine–dopamine releasing agent, recently failed to separate from placebo in phase III clinical trials of individuals with treatment-resistant depression, and clinical development was ...
Serotonin pathways are thought to modulate eating, both the amount as well as the motor processes associated with eating. The serotonergic projections into the hypothalamus are thought to be particularly relevant, and an increase in serotonergic signaling is thought to generally decrease food consumption (evidenced by fenfluramine , however ...
