Serotonin transporter

Psychiatrists, psychiatric residents, non psychiatric physicians, psychologists, philosophers or other health professionals or persons interested in this area can take part in the journal. This journal publishes original works, serotonin transporter, revision or updating articles, case reports serotonin transporter all psychiatry and mental health areas, epistemology, mind philosophy, bioethics and also articles about methodology of research and critical reading. SRJ is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it serotonin transporter a quantitative and qualitative measure of the journal's impact.

Serotonin transporters SERTs are largely recognized for one aspect of their function—to transport serotonin back into the presynaptic terminal after its release. Another aspect of their function, however, may be to generate currents large enough to have physiological consequences. The standard model for electrogenic transport is the alternating access model, in which serotonin is transported with a fixed ratio of co-transported ions resulting in net charge per cycle.

Serotonin transporter

This transport of serotonin by the SERT protein terminates the action of serotonin and recycles it in a sodium-dependent manner. A repeat length polymorphism in the promoter of this gene has been shown to affect the rate of serotonin uptake and may play a role in sudden infant death syndrome , aggressive behavior in Alzheimer disease patients, post-traumatic stress disorder and depression-susceptibility in people experiencing emotional trauma. Serotonin-reuptake transporters are dependent on both the concentration of potassium ion in the cytoplasm and the concentrations of sodium and chloride ions in the extracellular fluid. In order to function properly the serotonin transporter requires the membrane potential created by the sodium-potassium adenosine triphosphatase. 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 flip back out returning to its active state. The serotonin transporter removes serotonin from the synaptic cleft back into the synaptic boutons. Thus, it terminates the effects of serotonin and simultaneously enables its reuse by the presynaptic neuron. Neurons communicate by using chemical messengers like serotonin between cells. The transporter protein , by recycling serotonin, regulates its concentration in a gap, or synapse , and thus its effects on a receiving neuron's receptors.

How the serotonin story is being rewritten by new gene-based discoveries principally related to SLC6A4, the serotonin transporter gene, which functions to influence all cellular serotonin systems. The truth about genetic variation in the serotonin transporter gene and response to stress and medication. The amino acid sequences and three-dimensional 3D structures of NSS family members are closely related to serotonin transporter prokaryotic amino acid transporters LeuT and MhsT 3, serotonin transporter.

The serotonin transporter SERT regulates neurotransmitter homeostasis through the sodium- and chloride-dependent recycling of serotonin into presynaptic neurons 1 , 2 , 3. Major depression and anxiety disorders are treated using selective serotonin reuptake inhibitors—small molecules that competitively block substrate binding and thereby prolong neurotransmitter action 2 , 4.

Antidepressants are used to treat several psychiatric disorders; however, a large proportion of patients do not respond to their first antidepressant therapy and often experience adverse drug reactions ADR. A common insertion—deletion polymorphism in the promoter region 5-HTTLPR of the serotonin transporter SLC6A4 gene has been frequently investigated for its association with antidepressant outcomes.

Introduction Serotonin is highly implicated in the regulation of emotional state and the execution of cognitive tasks, so much so that the serotonin transporter genes 5-HTT, SLC6A4 and the serotonin receptor genes HTR1A, HTR1B, HTR2A have become the perfect candidates when studying the effects that these genes and their polymorphic variations have on depression characteristics.
