Research Overview
PE22-28 (Spadin) is a short neuroactive heptapeptide derived from Peptide E, a cleavage
product of the sortilin–propeptide pathway. In experimental neuroscience models it is used
to investigate selective TrkB receptor activation, BDNF-mimetic signalling, hippocampal
neurogenesis and modulation of neuronal survival pathways in vitro and in vivo, without
implying any therapeutic application.
Primary Research Areas
-
TrkB receptor & BDNF mimetic signalling:
Experimental models using PE22-28 as a selective TrkB agonist to probe BDNF-related
signalling cascades and downstream kinase activation.
-
Neurogenesis & synaptic plasticity:
In vitro and in vivo studies examining hippocampal neurogenesis, synaptic density
markers and plasticity-associated proteins under PE22-28 exposure.
-
Mood & stress-related models:
Laboratory models of depression, anxiety and stress resilience evaluating how TREK-1 /
TrkB pathway modulation influences behavioural and molecular readouts.
