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). This evidence concerns the gene MAP2 and Parkinson disease.
