What is PE-22-28?

PE-22-28 (Spadin analog — TREK-1 potassium channel blocker) is a 7-amino acid synthetic spadin-derived peptide. Synthetic spadin-derived peptide blocking the TREK-1 (TRAAK-related potassium channel-1) two-pore-domain K⁺ channel, which is overexpressed in depression models and reduces neuronal excitability. TREK-1 blockade increases firing rate and serotonin release — antidepressant mechanism without SSRI profile or sedation.

Research Applications

TREK-1 Channel Pharmacology

Two-pore-domain K⁺ channel block — neuronal excitability increase

Antidepressant Biology

Depression model research without SSRI target or sedation

Sortilin/Spadin Axis

Sortilin propeptide biology, TREK-1 regulation mechanism

Serotonin Release

5-HT release augmentation via neuronal depolarisation

Ion Channel Research

K⁺ channel pharmacology, membrane potential, firing rate studies
