Pro-inflammatory cytokines Eotaxin-1, I-309, IL-1β, IL-12p40, MIG, TNF RII, and anti-inflammatory IL-1ra and IL-12p70 were each found at significantly higher mean levels in the male PD Braak cerebellar mitochondria samples than in matched controls (Figure 4A: for p values see Supplementary Table 5). This evidence concerns the gene CXCL9 and Parkinson disease.
