Research profile

Selank is a research peptide used in preclinical laboratory models involving metabolic, mitochondrial, or immune pathways.

What is it?

Selank is a synthetic heptapeptide developed for investigational and in vitro research use, structurally derived from a fragment of the endogenous immunomodulatory peptide tuftsin. It is designed to interact with central nervous system signaling pathways without direct sedative or hormonal activity.

In preclinical and laboratory research models, Selank has been examined for its influence on neurotransmitter regulation, neuroimmune signaling, and stress-response modulation. These characteristics have made it a compound of interest in experimental studies focused on anxiety-related behavioral models, cognitive processing, and neuroadaptive communication pathways.

Mechanism of Interest

Tuftsin Analog — Studied as a synthetic analog of the immunomodulatory peptide tuftsin.
GABAergic Signaling — Investigated for influence on GABA-A receptor expression in neural models.
Monoamine Balance — Examined for effects on serotonin metabolism in vitro.

Key Research Applications

Neuropeptide research
Anxiolytic pathway modeling
Immunomodulatory peptide studies
