Selank is a synthetic regulatory heptapeptide with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro (TKPRPGP), synthesized by joining the natural immunomodulatory tetrapeptide Tuftsin (TKPR) to the metabolic stabilizing tripeptide Pro-Gly-Pro (PGP). Developed as a neuro-anxiolytic peptide, Selank modulates GABAergic and serotonergic neurotransmission without causing sedation, motor impairment, or physical dependence.

When researchers buy Selank, its dual neuro-immunomodulatory profile offers a compelling model for exploring the biological interface between the central nervous system and immune cytokine signaling.

Mechanism: Allosteric GABA Modulation and Serotonin Turnover

Selank exerts balanced neuromodulatory effects:
– Allosteric GABA Modulation: Enhances the binding affinity of gamma-aminobutyric acid (GABA) to GABA-A receptors, stabilizing neural excitability without producing the sedative or hypnotic side effects of benzodiazepines.
– Monoamine Neurotransmitter Regulation: Increases serotonin (5-HT) and dopamine metabolism in the prefrontal cortex and hippocampus.
– Immunomodulatory Tuftsin Core: Upregulates interleukin-6 (IL-6) in inflammatory states while suppressing excessive pro-inflammatory cytokines, stabilizing neuro-immune balance.

Frequently Asked Questions

❓ How does Selank compare to Semax?

Both share the stabilizing Pro-Gly-Pro tail, but Semax is derived from ACTH (focusing on cognition and BDNF stimulation), while Selank is derived from Tuftsin (focusing on GABA modulation and anxiety suppression).
