Selank is a synthetic peptide analog derived from the naturally occurring tetrapeptide tuftsin. It is widely utilized in laboratory research exploring cognitive function, neurochemical signaling, and immune system modulation.

Experimental models commonly investigate Selank’s interaction with neurotransmitter systems, including GABAergic and serotonergic pathways, in studies related to mood regulation, stress response, and cognitive performance. Research has also examined its potential influence on cytokine balance and neuroimmune signaling.
