Selank is a synthetic heptapeptide derived from tuftsin that acts as a positive allosteric modulator of GABAA receptors, enhancing inhibitory neurotransmission. It upregulates serotonin metabolism, modulates dopamine and norepinephrine, rapidly elevates BDNF expression, inhibits enkephalin-degrading enzymes, and provides immunomodulatory effects by balancing T helper cell cytokines.
