CD40 and Parkinson disease: In the RNA-seq PD dataset (Dumitriu), only two neural (DCX and MAP2) and two microglial (CD40 and ITGAM) markers showed significant alterations between PD and non-PD samples (Figure 4A), concordantly with no significant differences in cellular composition as estimated by CIBERSORTx (Figure 4B) using both the human and the mouse signatures (Supplementary Figures 12A,B).
