(A) Expression of selected differentially expressed genes (DEGs) in six microglial clusters. The DEGs of each microglial cluster were found using the Wilcoxon rank sum test for comparison. The genes shown were categorized by the functions related to lysosomal activity, lipid metabolism, homeostasis, adhesion molecules, proinflammatory cytokines and chemokines, MHC class I molecules, and MHC class II molecules. The data was scaled for plotting. LOC100426537: C-C motif chemokine 3-like. LOC100426632: C-C motif chemokine 4. (B) The characteristic biological processes in each microglial cluster by Gene Ontology (GO) pathway analysis. (C) The networks between DEGs and the biological processes in each microglial cluster.
