PTPRC and neoplasm: Among macrophages, which were the dominant immune cells infiltrating into the pancreatic TME, the proportion of M2 tumor-associated macrophages (M2-TAMs; CD45+CD11b+F4/80+Ly6ClowMHC-IIlow)39,40 increased from 12.4% in KC/Pd mice fed the control diet (GW for 0 days) to 19.2% and 65.2% in KC/Pd mice fed the GW diet for 3 and 9 days, respectively; GW also increased M2-TAMs in KC mice, although to a lesser degree (Fig. 5g).
