P21 cognitive peptide

P21 is a peptide fragment derived from CNTF (Ciliary Neurotrophic Factor) designed to activate the STAT3 signaling pathway, which promotes neurogenesis and cognitive function. Animal research demonstrates improved spatial memory, increased hippocampal neurogenesis, and enhanced BDNF expression. It is studied as a non-cytokine CNTF functional mimetic without the systemic side effects of full-length CNTF.
