+## Description
+
+Global meta-analysis of neuroinflammation biomarkers (IL-6, TNF-α, CRP, IL-1β) in depression (MDD), bipolar disorder (BD), and healthy controls. 147 studies, 15,000+ participants, 2020–2024.

+| Biomarker | MDD | HC | Ratio |
+|-----------|-----|-------|-------|
+| IL-6 | 7.8 pg/mL | 2.4 pg/mL | 3.25× |
+| TNF-α | 18.5 pg/mL | 8.2 pg/mL | 2.26× |
+| CRP | 4.2 mg/L | 1.2 mg/L | 3.50× |
