How Selank Works

Selank is a synthetic heptapeptide derived from the immunomodulatory peptide tuftsin (Thr-Lys-Pro-Arg) with a C-terminal Pro-Gly-Pro extension that enhances metabolic stability. It modulates the balance of Th1/Th2 cytokines, influences enkephalinase activity, and increases BDNF mRNA expression in the hippocampus. Selank produces anxiolytic effects comparable to benzodiazepines without sedation, cognitive impairment, or dependence by modulating GABAergic neurotransmission and monoamine metabolism in limbic structures.
