Trigeminovascular calcitonin gene-related peptide release and peripheral vascular responses in a mouse model of accelerated aging: Implications for migraine.
J Headache Pain | 2026
Laboratory / animal studySummary
Understanding age-related changes in migraine is crucial as life expectancy increases. Both aging and migraine are significant cardiovascular risk factors. Researchers studied how calcitonin gene-related peptide (CGRP) release changes with age. They examined this using a mouse model of accelerated aging. The study specifically focused on DNA repair-deficient Ercc1Δ/- mice. They compared CGRP release from the trigeminovascular system between these and wild type mice. Researchers also assessed the effects of aging on coronary vasodilatory responses. After sacrifice, they isolated tissues from various parts of the trigeminal system. They measured ex vivo KCl-induced CGRP release. Results showed CGRP release from the dura mater was significantly lower in Ercc1Δ/- mice. No differences in CGRP release were found in the trigeminal nucleus caudalis or trigeminal ganglion. Aging appears linked to reduced CGRP release, which may explain fewer migraine attacks in older individuals. Clinical relevance: This research suggests that aging may reduce CGRP release, potentially impacting migraine frequency.
Key Learning Points
- Aging may lead to a decrease in the release of CGRP, which is associated with migraine attacks.
- Understanding how aging affects migraine can help tailor treatment strategies for older patients.
- Both aging and migraine are important factors that can increase cardiovascular risks.
- Research on aging and migraine can provide insights into managing symptoms in older individuals.
- The study highlights the need for further research on the relationship between migraine and age-related biological changes.
