The HMRU is an integral part of the Danish Headache Center and Department of Neurology, Glostrup Hospital. At the HMRU, we seek to understand molecular mechanisms of migraine and to identify disease specific biomarkers (fingerprints of migraine). The core expertise of our members is human provocation models of migraine and ultrasound-based diagnostic imaging techniques used for visualizing vascular responses during experimentally induced migraine attacks. Over recent years, we have added additional expertise in functional and structural magnetic resonance imaging (incl. MR-angiography & functional MRI). These advanced imaging techniques constitute an important supplement to our provocation models and provide new and exciting insights into migraine pathophysiology. Furthermore, the HMRU has extended its field of interest by utilizing migraine genetic discoveries in human models of migraine to investigate functional consequences of genetic mutations. These achievements would not have been possible without strong collaborative work between the HMRU, the Functional Imaging Unit, Glostrup Hospital and other research groups.
In the future we intend to broaden our research program with novel human models of migraine and new imaging techniques (incl. PET) with the ultimate goal of defining predictive animal models of migraine, and discovery of targets for more specific and more effective mechanism-based anti-migraine drugs.
The hypotheses tested will be:
- Hypoxia provokes headache and migraine attacks with aura
- Carbon monoxide provokes headache and migraine attacks
- CGRP provokes more migraine attacks in patients with high genetic load than in patients with a low genetic load
- PACAP38 provokes more migraine attacks in patients with PACAP-associated gene variant
- Migraine attacks are associated with increased in blood-brain barrier permeability
- Natriuretic peptides dilates cerebral arteries and induces headache
- Patients undergoing endovascular procedures develop chronic headache
- Migraine attacks are associated with levels of serotonin in the brain
- Prevalence of migraine is higher in persons with the 3243A>G mutation in mitochondrial DNA
- Low frequency neuro-stimulation of SPG provokes migraine attacks in migraine patients
- Pre-treatment with antihistamine blocks PACAP38 induced migraine attacks
- The migraine brain is characterized by low levels of serotonin
