Selank originates from a peptide tuftsin, which is part of the immunoglobulin G molecule. Selank is a synthetic heptapeptide that has been tailored to mimic the effects of this endogenous peptide. It functions by modulating neurotransmitter systems in the brain, particularly by influencing the levels of serotonin and dopamine. Research on Selank began with its potential to enhance cognitive functions and reduce anxiety, stemming from its ability to regulate the balance of key neurochemicals. Scientists have explored its utility in improving mental clarity and emotional stability. Today, it is primarily studied for its effects on:
- Cognitive enhancement
- Anxiety reduction
- Mood stabilization
- Stress response modulation
- Neurotransmitter regulation
It is also being studied for its possible effects on immune system modulation.
