P21

Also known as P021, Ac-DGGLAG-NH2

CNTF-derived neurogenic peptidomimetic

A ciliary neurotrophic factor fragment studied for neurogenesis and reduction of tau pathology in models.

How it works

Mimics the active region of CNTF, stimulating hippocampal neurogenesis and BDNF signaling while inhibiting the leukemia inhibitory factor pathway linked to tau hyperphosphorylation.

What research has shown

Alzheimer model mice show improved memory performance, increased dendritic spine density and reduced tau pathology.
