What It Is

Selank modulates GABA-A receptor activity, exerting anxiolytic effects comparable to benzodiazepines without dependence or sedation. It enhances serotonergic neurotransmission by increasing serotonin uptake in neurons and upregulates expression of BDNF and enkephalins. It stimulates the release of endogenous opioid peptides (Met-enkephalin), contributing to stress reduction and mood stabilization. It also modulates the immune system via Tuftsin-like effects, upregulating IL-2, IL-6, and NK cell activity. The Pro-Gly-Pro tail stabilizes the peptide against enzymatic degradation.

Mechanism of Action

Selank modulates GABA-A receptor activity, exerting anxiolytic effects comparable to benzodiazepines without dependence or sedation. It enhances serotonergic neurotransmission by increasing serotonin uptake in neurons and upregulates expression of BDNF and enkephalins. It stimulates the release of endogenous opioid peptides (Met-enkephalin), contributing to stress reduction and mood stabilization. It also modulates the immune system via Tuftsin-like effects, upregulating IL-2, IL-6, and NK cell activity. The Pro-Gly-Pro tail stabilizes the peptide against enzymatic degradation.

Key Research Papers
