Migraine immune cell gene targets and their relationship to psychiatric disorders.
Article in The journal of headache and pain, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMigraine frequently co-occurs with psychiatric disorders, yet the immunogenetic mechanisms linking these conditions remain largely unexplored.
methodsUsing cis-eQTL data from 28 immune cell subtypes (1,925 donors) and GWAS summary statistics for migraine and five psychiatric disorders, we performed single-cell transcriptome-wide Mendelian randomization, Bayesian colocalization, genetic correlation, and cross-disease pleiotropy analyses. Independent replication was performed using external datasets.
resultsMigraine and its subtypes showed significant positive genetic correlations with all five psychiatric disorders (rg = 0.39-0.73). We identified 83 immune cell gene targets for migraine, 13 for migraine with aura, and 19 for migraine without aura. Among these, 6 targets showed shared associations with anxiety and 1 with depression. Three prioritized genes-HLA-A, CDK2AP1, and TTC24-demonstrated cross-disease pleiotropic effects. Notably, HLA-A in cDC1 exhibited discordant pleiotropy (protective for migraine with aura, risk for depression), with known drug-gene interactions involving antiepileptics and tricyclic antidepressants.
conclusionsThese findings suggest that immune cell-specific genes, particularly HLA-A, CDK2AP1, and TTC24, may bridge migraine and psychiatric disorders, offering potential candidates for further investigation into shared immunogenetic mechanisms. CLINICAL TRIAL NUMBER: Not applicable.
