IL1B and neoplasm: Figure 2C shows the level of expression of over 40 immune and pro-tumor genes by cells within each cluster, including a multitude of inflammatory cytokines/chemokines (IL1B, CXCL1, CXCL5, PPBP (CXCL7), CCL2, CXCL8), extracellular matrix components and modulators (FN1, COL23A1, VCAN, TGFBI, MMP9), and genes indicating altered lipid metabolism (APOE, APOC1, GPNMB, FABP5).
