The immune cell infiltration analysis of substantia nigra between PD patients and healthy controls. (A) The landscape of immune cell infiltration in PD and healthy controls. There were eleven immune cells with significant difference (neutrophil, mast cell, T follicular helper cell, plasmacytoid dendritic cell, MDSC, natural killer T cell, type 1 helper cell, effector memory CD8 T cell, immature B cell, immature dendritic cell, and CD 56 bright natural killer cell). (B) Principal component analysis for immune cell infiltration in PD and healthy controls. (C) Venn diagram of genes screened via WGCNA and immune-related genes dataset. ns, p > 0.05, *p < 0.05, **p < 0.01, ***p < 0.001.
