P21

Full name: P21 Peptide (CNTF-derived)

A short peptide derived from ciliary neurotrophic factor (CNTF) that activates the JAK/STAT3 signaling pathway in the hippocampus. Animal research demonstrated improved working memory, enhanced neurogenesis, and potentiated long-term potentiation (LTP). Considered one of the emerging nootropic peptides with potential applications in age-related cognitive decline.
