IRF5 and cancer: Our results indicate significant correlations between the expression of SDC1 in B cells, TGFB1 in Treg cells, CD68 in TAMs; NOS2 and IRF5 in M1 macrophages; FUT4 in neutrophils; ITGAM and ENTPD1 in MDSCs; CD83 in DC; KIT in mast cells; PDPN in endothelial cells; MFAP5 in cancer‐associated fibroblasts (CAF); and PD1, BTLA, and CD160 in Tex cells with most gelsolin superfamily members in ECs (Figure 16A).
