In female HC and PD, but not male, IFNγ response was significantly higher than IL-5 (p=0.0008 and 0.005 respectively, one-way ANOVA with Dunnett’s test) and trended higher in comparison to IL-10 (p=0.08 female HC, p=0.16 female PD; one-way ANOVA with Dunnett’s test). Here, IFNG is linked to Parkinson disease.
