New Nanoparticle Therapy Targets Migraines at the Source

Research Summary

A recent study published in CNS Neuroscience & Therapeutics explores the role of metallothionein-2 (Mt2) in migraine pathophysiology, highlighting its potential as a new therapeutic target. Researchers used an EGR1-GFP reporter system to identify activated cortical cells in a migraine model, revealing significant upregulation of Mt2 in vascular endothelial cells. To investigate Mt2's function, they developed nanoparticles with Mt2-shRNA and administered them to mice, observing reductions in migraine-related behaviors like photophobia and hyperalgesia. Two-photon microscopy showed decreased cerebral vasodilation, and pathway analysis linked Mt2 to vascular and inflammatory pathways. These findings suggest Mt2 as a key player in migraine development.
