Selank 30mg· 30mg

Selank exerts its reported effects through a combination of mechanisms that bridge immunological and central nervous system signaling. As an analog of tuftsin, the peptide retains affinity for tuftsin-recognizing sites on monocytes, macrophages, and microglia, where engagement has been associated with modulation of phagocytic activity and of cytokine release. Russian and collaborating investigators have reported that selank alters the balance of pro-inflammatory and anti-inflammatory cytokines in plasma and central nervous system tissue, with reductions in interleukin-6 frequently described.

Within the central nervous system, preclinical work has reported modulation of GABAergic transmission, with observations consistent with potentiation of GABA-A receptor function in hippocampal and cortical preparations contributing to the anxiolytic-like behavioral profile. Additional reports describe upregulation of brain-derived neurotrophic factor (BDNF) expression in hippocampal tissue, modulation of serotonergic and noradrenergic turnover, and inhibition of enkephalin-degrading enzymes, which together provide a candidate framework for the observed effects on anxiety-like behavior and on learning and memory in rodent paradigms. The relative contribution of each pathway to the in vivo phenotype remains an open question in the published literature.
