Selank
Overview
Selank is a synthetic peptide derived from the endogenous tetrapeptide tuftsin, studied for its potential effects on anxiety modulation and cognitive function.
Research Interest Areas
- Anxiety and stress response
- Cognitive function
- Immune modulation
Proposed Mechanism
- Modulates GABAergic signaling
- May influence serotonin pathways
- Interacts with immune system signaling
What the Research Suggests
Human Studies:
- Observed anxiolytic (anti-anxiety) effects in some studies
- Potential improvements in cognitive performance under stress
Preclinical Studies:
- Behavioral improvements in stress models
- Neurochemical modulation observed
Evidence Summary
- Human Evidence: Limited
- Animal Evidence: Moderate
- Mechanistic Support: Moderate
- Long-Term Safety: Limited
Limitations
- Limited large-scale clinical trials
- Variability in study design and outcomes
- Long-term safety not well established
Key Takeaway
Selank is being explored for its role in stress and cognitive regulation, though current evidence remains early-stage.
