Multiple M0-homeostatic microglial transcripts were repressed in C1QC+ macrophages, including CST3, NFKB1, JUN, and EGR1, while the key transcripts of dysfunctional microglia in neurodegenerative diseases, including APOE, TREM2, and LGALS3, were strongly upregulated32 (Fig. 3d). Here, NFKB1 is linked to neurodegenerative disease.
