PE-22-28

PE-22-28 is a heptapeptide (GVSWGLR) corresponding to a short, more stable section of the peptide spadin. Spadin blocks the potassium channel TREK-1; animal models examine how this affects neurogenesis and neuronal plasticity.

Research profile

What is PE-22-28?

Spadin derives from the propeptide of the sortilin receptor. PE-22-28 corresponds to amino acids 22 to 28 of this section (773.9 g/mol) and is more stable in the body than full spadin.

Research status

The potassium channel TREK-1 influences neuronal excitability. Animal models examine whether blocking it changes the formation of new neurons and the adaptability of neural networks. The data are limited to a few preclinical studies.

Status

Not approved. Research use only; also part of the neuro blend.
