Regulatory T cell levels in migraine: A systematic review and meta-analysis.
J Headache Pain | 2026
Systematic review / meta-analysisSummary
This systematic review and meta-analysis examined regulatory T (Treg) cell levels in migraine patients. Researchers searched databases like PubMed, Embase, and Cochrane for relevant studies. They identified 1,162 studies but included only five in the narrative review. Four studies were included in the meta-analysis. The analysis used a random-effects model to pool data. Standardized mean differences (SMD) compared Treg levels in migraine and control groups. Three of five studies showed decreased Treg levels in migraine patients. Additionally, two of three studies found low Treg levels in interictal episodic migraine patients. The meta-analysis revealed a significant decrease in Treg levels, with an SMD of -4.21. This finding had a p-value of 0.02 and an I² of 98.3%. Overall, Treg levels appear decreased in migraine, suggesting they may help understand migraine mechanisms. However, limited data indicate the need for further research on their significance. Clinical relevance: This study highlights the potential role of Treg cells in migraine, suggesting new therapeutic avenues for treatment.
Key Learning Points
- Migraine patients may have lower levels of regulatory T cells compared to those without migraines.
- Understanding Treg cell levels could provide insights into the mechanisms behind migraines.
- The analysis found a significant decrease in Treg levels among migraine sufferers.
- Further research is necessary to fully understand the role of Treg cells in migraines.
- This study suggests that targeting Treg cells might open new treatment options for migraine patients.
