  Serotonin - Wikipedia, the free encyclopedia
NCCC1=CNC2=C1C=C(O)C=C2 Serotonin (5-hydroxytryptamine, or 5-HT) is a monoamine neurotransmitter synthesised in serotonergic neurons in the central nervous system and enterochromaffin cells in the gastrointestinal tract.
This is through the specific monoamine transporter for 5-HT, 5-HT reuptake transporter, on the presynaptic neuron.
The effects of MDMA, which may in fact be the effects of the 5-HT which floods synapses during an MDMA "roll," include feelings of well-being, comfort, tactile sensitivity, and, at very high doses, feelings of emotional empathy or entactogenesis.

Thus, the monoamine transporters are the primary high affinity targets for cocaine in the brain and drug-induced changes in transporter kinetics and number will strongly influence the effects of subsequent drug administration.
While changes in monoamine transporter mRNAs, and binding sites have been implicated in chronic cocaine administration, there are no studies investigating relevant alterations in transporter function, regulation and cell surface expression in presynaptic terminals that are associated with cocaine self-administration, extinction and reinstatement.
To accomplish this a number of dependent variables related to transporter function will be quantified, including 1) expression, transport activity, surface distribution, 2) phosphorylation state of transporters, transporter protein-protein association and 3) the degree to which the monoamine transporters are regulated by presynaptic auto- and hetero-receptors.

The biogenic monoamine transporters are the primary mechanism for clearance of their respective neurotransmitter from the extracellular space and serve as important regulators of signal amplitude and duration at synapses.
These drugs either block transport of substrates as is the case for SSRIs and cocaine, or are carrier substrates, such as amphetamines, which both inhibit uptake and stimulate efflux of intracellular neurotransmitter.
One mechanism for acute presynaptic regulation of dopamine transport is modulation of transporter number through the trafficking of carriers to and from the cell surface.

 VMAT, AChT, NET, Proline, SERT, Tau transporters
Vesicular monoamine transporters (VMATs) catalyze transport and storage of monoamines, serotonin, dopamine, norepinephrine, epinephrine, and histamine.
In contrast to the plasma membrane transporters for dopamine, norepinephrine, and 5-HT which show relative substrate specificity, the monoamine transporter recognizes various monoamine with similar affinity.
It was therefore speculated that either similar or identical transporters mediate the monoamine transport in all the tissues.

The extraneuronal monoamine transporter from rat (EMTr) was heterologously expressed by stable transfection in human embryonic kidney 293 cells and characterized in radiotracer experiments.
Since the extent of activation depends markedly on the chemical structure of the monitored substrate, involvement of a receptor-mediated signalling pathway or recruitment of transporter reserve are implausible.
We speculate that activation may serve to keep the transporter working for specific substrates in the face of inhibitors.
