Selank: A Neuropeptide Research Overview
17 June 2026
Selank is a synthetic neuropeptide derived from the immunomodulatory peptide tuftsin. It is studied in neuroscience research focused on the stress response, anxiety-related endpoints and immune signalling.
What is Selank?
Selank is a stabilised analogue of a tuftsin fragment. In research it is used as a tool to study peptide effects on the central nervous system and on immune-related pathways without the broader activity of the parent molecule.
Pathways studied in the literature
- Modulation of GABAergic and serotonergic signalling in animal models.
- Stress and anxiety-related behavioural endpoints.
- Brain-derived neurotrophic factor (BDNF) expression.
- Immune and interferon-related signalling (reflecting its tuftsin origin).
Summary of research findings
Selank research is predominantly preclinical, examining behavioural and neurochemical endpoints in animal models. It is frequently studied alongside Semax. Interpretation should remain anchored to the specific experimental models.
