Summary of mechanisms of induction of immunosuppressive monocytes. Induction of immunosuppressive monocytes by GBM tumor cells can proceed through a number of different mechanisms, including direct cell surface-mediated signaling, uptake of proteins with subsequent cytosolic effects, or signaling by tumor-derived small RNAs. Tumor-derived EVs are capable of signaling by any of these mechanisms.
