Migraine is the third most prevalent disease worldwide and is estimated to affect upwards of 14% of the population. Our lab has used novel preclinical models to identify the delta opioid receptor (DOR) as a therapeutic target for multiple headache disorders, including migraine. We have also investigated the relationship between DOR with the pro-migraine peptide, CGRP. There is regional variation between the co-expression of DOR with CGRP or its receptor in the trigeminal complex. This work indicates that DOR agonists can moderate both CGRP release and signaling, thus regulating pro-migraine effects at two different levels. Recent work in our lab has also explored how cytoarchitectural changes in pain processing regions are critical for the maintenance of the chronic migraine state. We show that there is decreased neuronal complexity in two different models of migraine, and that restoration of tubulin dynamics, directly by HDAC6 inhibitor or indirectly by CGRP receptor antagonist, can inhibit migraine-associated symptoms. These studies provide fundamental information on how cytoskeletal dynamics are altered in chronic migraine, and form the basis for the development of HDAC6 inhibitors for headache treatment.
