Special Issue Information

Dear Colleagues,

Chronic headache disorders affect approximately 30% of the general population. Migraine, in particular, not only lowers quality of life but also causes considerable productivity loss worldwide. Calcitonin gene-related peptide (CGRP)-mediated sensitization of the trigeminovascular system is known to be a crucial mechanism underlying migraine attacks, as evidenced by the excellent efficacy of CGRP-targeting therapy in migraine control. However, it is important to acknowledge that a subset of migraine sufferers remains resistant to existing treatment options. Therefore, the exploration of novel therapeutic targets, including pituitary adenylate cyclase-activating polypeptide (PACAP), amylin, transient receptor potential (TRP) channels, and protease-activated receptor 2 (PAR2), is essential for advancing migraine therapeutics. Tension-type headache is the most common primary headache disorder. However, there is only a paucity of data on its pathophysiology. Cluster headache is characterized by excruciating unilateral head pain, accompanied by ipsilateral cranial autonomic symptoms. Although recent genetic data have identified several novel susceptible loci for cluster headaches, little is known about the pathophysiology of cluster headaches. Further, many patients suffer from chronic post-traumatic headaches and post-stroke headaches. Given these unmet needs, we should develop novel therapeutic strategies based on a deeper understanding of disease mechanisms. This Special Issue invites high-quality contributions to this end.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The gut–brain axis regulates brain functions and maintains central nervous system homeostasis and intestinal balance. Migraine patients often present with gastrointestinal (GI) comorbidities, with stronger associations observed in chronic migraine (CM) than in episodic migraine (EM).

The gut–brain axis regulates brain functions and maintains central nervous system homeostasis and intestinal balance. Migraine patients often present with gastrointestinal (GI) comorbidities, with stronger associations observed in chronic migraine (CM) than in episodic migraine (EM). To investigate migraine-related GI alterations, nitroglycerin (NTG)-induced mouse models of EM (N = 15) and CM (N = 15) were established using single or repeated NTG injections (10 mg/kg). EM mice were euthanized 4 h after a single injection, whereas CM mice received NTG every other day for 9 days and were euthanized after the fifth injection. On the day of sacrifice, GI tissues were analyzed for morphological changes, cytokine expression, calcitonin gene-related peptide (CGRP) levels, and immune cell profiles. NTG-treated groups exhibited significant reductions in both food intake and body weight compared with controls. In addition, colon length was markedly shortened in the chronic migraine (CM) model (p < 0.01). Molecular analyses revealed distinct cytokine expression profiles between models: the episodic migraine (EM) model showed increased levels of proinflammatory cytokines (IL-1β, IL-6, and IL-8; p < 0.01), whereas the CM model displayed elevated anti-inflammatory cytokines (IL-4, IL-10, and TGF-β; p < 0.01), particularly in the colon. CGRP expression was also markedly upregulated throughout the gastrointestinal tract, with the highest expression observed in the colon of CM mice (p < 0.01). Flow cytometric immune profiling further demonstrated divergent immune cell patterns, with increased Th17 (p = 0.0085) and B cell (p = 0.0199) populations in EM, while CM was characterized by enrichment of T cells (p = 0.0221), regulatory T cells (Tregs) (p = 0.0114), and macrophages (p = 0.0062), indicating more pronounced immune alterations in the distal colon. These findings indicate that CM involves more severe gut–brain axis dysregulation than EM, supporting the potential of gut-targeted therapies as adjunct strategies in chronic migraine. Full article
