Research Data

What Is PE 22-28?

PE 22-28 is a synthetic heptapeptide derived from the DSIP sequence, studied as a BDNF (Brain-Derived Neurotrophic Factor) loop 4 mimetic. Research has focused on antidepressant-like activity via TrkB receptor activation, anxiolytic effects, and stress-resilience models — without the limitations of full BDNF administration.

Research Context

TrkB receptor (BDNF receptor) activation research
Antidepressant and anxiolytic activity in animal models
Stress-resilience and HPA axis pathway studies
Comparison with Cerebrolysin in neurotrophic research
Blood-brain barrier penetrability studies
