  2. 5-HTTLPR - Wikipedia

    en.wikipedia.org/wiki/5-HTTLPR

    5-HTTLPR (serotonin-transporter-linked promoter region) is a degenerate repeat (redundancy in the genetic code) polymorphic region in SLC6A4, the gene that codes for the serotonin transporter. Since the polymorphism was identified in the middle of the 1990s, [ 1 ] [ 2 ] it has been extensively investigated, e.g., in connection with ...

  3. Serotonin transporter - Wikipedia

    en.wikipedia.org/wiki/Serotonin_transporter

    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 ...

    en.wikipedia.org/wiki/Biology_of_depression

    A 2003 study proposed that a gene-environment interaction (GxE) may explain why life stress is a predictor for depressive episodes in some individuals, but not in others, depending on an allelic variation of the serotonin-transporter-linked promoter region . [15]

  5. Monoamine neurotransmitter - Wikipedia

    en.wikipedia.org/wiki/Monoamine_neurotransmitter

    Specific transporter proteins called monoamine transporters that transport monoamines in or out of a cell exist. These are the dopamine transporter (DAT), serotonin transporter (SERT), and the norepinephrine transporter (NET) in the outer cell membrane and the vesicular monoamine transporter ( VMAT1 and VMAT2 ) in the membrane of intracellular ...

  6. Monoamine transporter - Wikipedia

    en.wikipedia.org/wiki/Monoamine_transporter

    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 ...

  7. 5-HT2B receptor - Wikipedia

    en.wikipedia.org/wiki/5-HT2B_receptor

    5-Hydroxytryptamine receptor 2B (5-HT 2B) also known as serotonin receptor 2B is a protein that in humans is encoded by the HTR2B gene. [ 5 ] [ 6 ] 5-HT 2B is a member of the 5-HT 2 receptor family that binds the neurotransmitter serotonin (5-hydroxytryptamine, 5-HT).

  8. Epigenetics of depression - Wikipedia

    en.wikipedia.org/wiki/Epigenetics_of_depression

    Epigenetics of depression is the study of how epigenetics (heritable characteristics that do not involve changes in DNA sequence) contribute to depression. Major depressive disorder is heavily influenced by environmental and genetic factors.

  9. Neurotrophic hypothesis of depression - Wikipedia

    en.wikipedia.org/wiki/Neurotrophic_hypothesis_of...

    Individuals with the BDNF Val66Met polymorphism are more susceptible to depression, anxiety and bipolar disorder. [4] Furthermore, people with these gene have been found to have decreased hippocampal volume, which is a common structural change associated with depression. This genes results in decreased activity-dependent secretion of BDNF.
