About PE-22-28
- What it is
- PE-22-28 is a synthetic seven amino acid peptide derived from spadin, a fragment of the sortilin propeptide. In rodent and laboratory studies it blocks the TREK-1 potassium channel with high potency and produced antidepressant-like effects along with signs of increased hippocampal neurogenesis. It has not been tested in humans and remains an investigational research compound.
- How it works
- It inhibits the TREK-1 potassium channel, an action linked in animal models to antidepressant effects and enhanced neurogenesis.
