The results showed that CD74 expression was relatively high in B cells, monocytes/macrophages and pre-dendritic cells (pDCs), IRF1 expression was relatively high in endothelial cells, myoepithelial cells, and Cancer-associated fibroblasts (CAFs) and PSME2 expression was relatively high in monocytes/macrophages, cycling monocytes/macrophages, cycling T cells and conventional dendritic cells (cDCs) (Figure 3B). The gene discussed is IRF1; the disease is cancer.
