Cytokine expression in bulk RNA-seq and single-nuclei RNA-seq datasets. (A) Bulk analysis of SN tissue displays higher expression of IL1B and IL10 in IPD (FDR = 0.023; FDR = 0.0067). (B) Single-nuclei analysis of the human midbrain shows that the overall expression of cytokines is higher in microglia (3903 cells) than in neurons (5314 cells). (C) Cytokines are expressed in a large number of IPD and control microglia. Z-score-scaled average expression per cluster shows higher levels in IPD compared to control microglia. “DotPlot” function (Seurat package) was used to visualize expression and percentage of cytokine-expressing cells. p < 0.05; ∗∗p < 0.01; IPD, idiopathic PD.
