Mechanism of action

Selank is a synthetic heptapeptide derived from the immunomodulatory peptide tuftsin. Research focuses on its modulation of GABAergic neurotransmission and influence on BDNF expression, studied in anxiety and stress behavioral models.

It is also reported to inhibit enkephalin-degrading enzymes and to modulate cytokines such as IL-6 in immunological assays — all within research contexts.
