Selank is a synthetic heptapeptide analogue of the immunomodulatory tetrapeptide tuftsin, with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro. It has been studied for its nootropic, anxiolytic, and neuroprotective effects. Research suggests Selank modulates GABAergic and serotonergic neurotransmission, enhances brain-derived neurotrophic factor (BDNF) expression, and improves memory and learning in preclinical models. It has also been shown to influence immune function, making it a unique peptide at the intersection of neurology and immunology research.
