Among their compelling findings, the association between the endothelial cell-specific polygenic risk score (EC-PRS) - which consists of SNPs associated with coronary artery disease - and a reduced risk of migraine headaches stood out, although not being the study's primary aim. Migraine imposes a substantial individual and socioeconomic burden worldwide. Beyond its neurological manifestations as a primary headache disorder, migraine has increasingly been recognized as an independent and underappreciated cardiovascular risk factor, linked to major cardiovascular and cerebrovascular events. However, the biological underpinnings of this association remain poorly understood, particularly since they do not appear to be mediated through traditional or atherosclerotic pathways, and they are not associated with established cardiovascular risk factors. In this Correspondence, we build upon the findings of Marston et al. and contextualize them within the broader framework of migraine as a neurovascular disorder. Drawing from translational evidence, we propose a conceptual model that integrates findings regarding EC-PRS into the complex biological interplay linking migraine and cardiovascular disease, including coronary artery disease.

Notwithstanding, the impact of AEA and 2-AG on neuronal firing of meningeal afferents, which is relevant to the genesis of migraine pain, remains elusive.</p><p><strong>Methods: </strong>The impact of AEA and 2-AG on meningeal nerve afferent firing was examined through electrophysiological evaluation upon application of 50 mM KCl with or without DMSO, exogenous AEA (10 µM), or 2-AG (10 µM) to separate groups of C57BL/6J mouse hemiskull preparations. At the end of each experiment, capsaicin (1 µM), an agonist of TRPV1 channels, was tested, as a positive control of presumably nociceptive firing. Advanced clustering and spectral analysis on the electrophysiological data allowed differentiating spiking patterns with respect to their temporal and neurochemical profiles.

AEA first produced a short, mild activation in firing, which was followed by a long-lasting reduction. Instead, 2-AG directly led to a short-lasting reduction in firing. Cluster analysis revealed that the transient activation by AEA involved fibers with small-amplitude spikes fired at rates of 1-2 Hz, whereas the persistently suppressed fibers consisted of high-amplitude spikes fired at rates exceeding 10 Hz. Only AEA inhibited subsequent capsaicininduced firing in the afferents long after AEA application, suggesting a broader mode of action for AEA than 2-AG.

Further, potential triggers of migraine, such as stress and disruption to feeding habits, also impact hypothalamic mechanisms. The higher prevalence of migraine in women compared to men suggests a link to hormonal fluctuations involving estrogen, progesterone, and prolactin. These hormones interact with the hypothalamus, potentially influencing the onset and severity of migraine episodes. Additionally, the hypothalamus synthesizes neuropeptides such as orexins, neuropeptide Y, PACAP, oxytocin, and vasopressin, which are all implicated in migraine mechanisms.
