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, revision or updating articles, case reports of 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 provides a quantitative and qualitative measure of the journal's impact. SNIP measures contextual citation impact by wighting citations based on the total number of citations in a subject field. 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.. A review of research reports that have studied the effects of variations in the serotonin transporter and receptor genes on different clinical features of depression..

The interaction between the serotonin transporter SERT linked polymorphic region 5-HTTLPR and adverse early life stressing ELS events is associated with enhanced stress susceptibility and risk to develop mental disorders like major depression, anxiety, and aggressiveness. In particular, human short allele carriers are at increased risk. However, underlying neuromolecular mechanisms of the mal adaptive responses to adversity displayed by SERT rodents remain to be elucidated. Several reasons may underlie these failures, e. Finally, further research is warranted using more severe stressors in animal models. Major depressive disorder, also known as major depression, carries the heaviest burden amongst all mental and behavioral disorders and is globally the largest contributor to years lived with disability Ferrari et al. At any given time, over 4 percent of the global population suffers from major depression, with females being 1. Depression is diagnosed when signs and symptoms persist for at least 2 weeks and include daily feelings of depression, anxiousness or hopelessness and despair, insomnia, and anhedonia, i. It has been widely acknowledged that both genetic and environmental factors contribute to the psychopathology of major depression, most likely by interacting in a complex and interdependent manner. For instance, aversive early life events such as childhood maltreatment contribute substantially to the risk of developing depression Heim et al. However, the responsivity to such aversive early life events is significantly affected by the individual's genetic background. The serotonin transporter is of major importance in regulating synaptic serotonin 5-HT concentrations and signaling, and 5-HT synapses play a central role in the neural circuitry controlling mood and temperament.

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.

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. The alternating access model, however, cannot account for all the observed currents through SERT or other monoamine transporters. Furthermore, SERT agonists like ecstasy or antagonists like fluoxetine generate or suppress currents that the standard model cannot support.

Rudnick and Sandtner review the history of serotonin transporter research in light of structural and electrophysiological advances. Serotonin 5-hydroxytryptamine [5-HT] is accumulated within nerve endings by the serotonin transporter SERT , which terminates its extracellular action and provides cytoplasmic 5-HT for refilling of synaptic vesicles.
