Background

About Selank Peptide UK

Selank is a synthetic heptapeptide derived from a sequence related to the naturally occurring immunomodulatory peptide tuftsin. It is used in neurobiological research examining neurotransmitter systems, stress responses, cognition and interactions between neural and immune signalling.

Research

Selank Research

Selank research has explored GABAergic signalling, gene-expression changes, serotonergic and other neurotransmitter pathways, learning and memory models, stress responses and neuroimmune regulation (Learn more). Its literature is notable for spanning both neurochemical and immune-related mechanisms, making the peptide relevant to research on the interface between stress, cognition and signalling, alongside related nootropic and neuro-research peptides such as [Semax] and [DSIP].
