Within these three AD modules, we observed enrichment of pro-inflammatory genes in the Magenta module (Ptgs2, Il12b, Tlr2, Hif1a, Cd69, Il1b, Cxcl16 and Irg1) and anti-inflammatory and phagocytic genes in the Yellow module (Igf1, Dpp7, Apoe, Spp1, Cd200r4 and Lpl) [38] while the Blue module contained several homeostatic microglial genes (Tmem119, P2ry12, Mtss1 and Tgfbr1, Fig. 2d) [39]. The gene discussed is IL1B; the disease is Alzheimer disease.
