Summary
Migraine subtypes, migraine with aura (MA) and migraine without aura (MO), have distinct genetic and spatial mechanisms. MA involves neuroimmune-epigenetic factors, while MO is linked to vascular-metabolic issues, offering new therapeutic targets.
Area of Science:
- Genomics
- Neuroscience
- Spatial Biology
Background:
- Migraine, a neurological disorder with subtypes (MA and MO), presents genetic and spatial heterogeneity.
- Understanding the molecular mechanisms in tissue microenvironments is crucial for targeted migraine therapies.
Purpose of the Study:
- To investigate the spatially resolved molecular mechanisms underlying migraine heterogeneity.
- To identify subtype-specific genes and pathways for targeted therapeutic development.
Main Methods:
- Integrated genome-wide association study (GWAS) data with transcriptomic, epigenomic, and spatial transcriptomics (sc-ST).
- Employed multi-omics analyses including LDSC, HDL, SMR, FUSION, MAGMA, JTI-PrediXcan, and PoPS for gene prioritization.
- Utilized gsMap algorithm for genetically informed spatial mapping of cells and subtype-associated cellular architectures.
Main Results:
- Confirmed strong genetic correlations between MA and MO but revealed divergent functional architectures.
- MA is enriched in conserved regulatory elements and neural crest-derived tissues; MO is linked to vascular pathways and gut-brain interfaces.
- Identified high-confidence cross-subtype genes (e.g., LRP1, PHACTR1, STAT6) and subtype-specific genes for MA (neuronal regulators) and MO (vascular/metabolic).
Conclusions:
- Migraine heterogeneity is driven by spatially constrained mechanisms: neuroimmune-epigenetic dysregulation in MA and vascular-metabolic perturbations in MO.
- Key identified genes and pathways offer actionable targets for developing subtype-specific migraine therapies.
- This study bridges genetic architecture with spatial biology to advance migraine pathogenesis understanding and precision interventions.
