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.
The 7 general serotonin receptor classes include a total of 14 known serotonin receptors. [9] The 15th receptor 5-HT 1P has been distinguished on the basis of functional and radioligand binding studies, its existence has never been definitely affirmed or refuted. [10] [11] The specific types have been characterized as follows: [12] [13] [14]

The serotonin transporter first binds a sodium ion, followed by the serotonin, and then a chloride ion; it is then allowed, thanks to the membrane potential, to flip inside the cell freeing all the elements previously bound. Right after the release of the serotonin in the cytoplasm a potassium ion binds to the transporter which is now able to ...
Fluoxetine is a selective serotonin re-uptake inhibitor (SSRI), which blocks re-uptake of serotonin by the presynaptic cell which increases the amount of serotonin present at the synapse and furthermore allows it to remain there longer, providing potential for the effect of naturally released serotonin. [64]
A given receptor can act as either an autoreceptor or a heteroreceptor, depending upon the type of transmitter released by the cell on which it is embedded. Autoreceptors may be located in any part of the cell membrane: in the dendrites, the cell body, the axon, or the axon terminals. [1]
It has been observed that the pathology of depression involves dysfunction of monoamine neurotransmitter circuits in the CNS, particularly of serotonin and norepinephrine. Selective serotonin reuptake inhibitors (SSRIs) are the most widely used antidepressant and include fluoxetine (Prozac), citalopram (Celexa), and fluvoxamine (Luvox). These ...
