Excerpt
Migraine attacks originate in the meninges which are densely innervated by trigeminal nerve fibers. Upon stimulation, endothelial cells of dural blood vessels secrete nitric oxide and as a consequence, neuropeptides are released from trigeminal nerve fibers. This, in turn, leads to meningeal plasmaproteinextravasation (PPE) and vasodilation. Inflammatory components such as PPE and vasodilation serve as indicators for migraine attacks in animal models. A guinea pig migraine model was described in which the partial 5-HT2B/2C receptor agonist meta-Chlorphenylpiperazine (mCPP) is applied to induce PPE in the dura mater. We have transferred this model to mice. …
