FIGURE 1.
Four immune cell fractions in the blood from PD compared with those from HC are significantly different and the correlation between immune cells and DEGs in the blood of patients with PD. (A) The main immune cell fractions in the blood from PD and HC. The ordinate represents the immune cell fractions, and the abscissa represents the immune cell types. The blue dots represent HC samples, and the red dots represent PD samples. (B) KEGG pathway–NK cell-mediated cytotoxicity enriched in PD using GSEA. (C) Correlation between PTGDS and immune cells. (D) Correlation between MMP9 and immune cells. *p < 0.05, **p < 0.01.
