Research Applications
Rapid-onset antidepressant research. TREK-1 channel pharmacology. Non-monoaminergic depression treatment. Treatment-resistant depression.
Mechanism of Action
Spadin selectively blocks TREK-1 potassium channels, increasing neuronal excitability in hippocampus and cortex. TREK-1 blockade enhances serotonergic neurotransmission, increases BDNF expression and hippocampal neurogenesis, and activates CREB signaling — effects similar to chronic SSRI treatment but occurring within days.

Spadin: A Novel Antidepressant Targeting TREK-1
Mazella J, Petrault O, Lucas G, et al.
Frequently Asked Questions
Spadin is a 17-amino acid peptide derived from the propeptide of sortilin (a neuronal sorting receptor) that acts as a selective antagonist of the TREK-1 potassium channel. TREK-1 is a two-pore domain potassium channel involved in mood regulation — TREK-1 knockout mice display a depression-resistant phenotype. Spadin blocks TREK-1, producing rapid antidepressant effects in animal models within 4 days (versus 2-4 weeks for SSRIs). It represents a novel, non-monoaminergic approach to depression treatment.
