How does P-21 work?
Synthetic peptide that mimics CNTF (ciliary neurotrophic factor) action on neurogenesis pathways. Pre-clinical only, mechanism partially characterized. In plain terms, P-21 is synthetic ciliary neurotrophic factor (CNTF)-mimetic peptide. Targets neurogenesis. Pre-clinical / early research compound. Mechanistic detail like this comes largely from preclinical and early research, the human picture is limited.
What people use it for
- Researchers studying CNTF pathways
- Cognitive-decline research contexts
- Educational reference, limited human data
