Research Data

What Is P21?

P021 (P21) is a CNTF-derived tetrapeptide that crosses the blood-brain barrier and is studied for its effects on neurogenesis, synaptic plasticity, and tau pathology. Research in transgenic Alzheimer's mouse models has shown improved cognitive performance and reduced amyloid/tau burden. Among the most novel neurogenic research peptides available.

Research Context
