Current advances in cancer immunotherapy are hindered by the immunosuppressive nature of the tumor microenvironment (TME). Cancer-associated fibroblasts (CAFs) are a key component of the TME that contribute to suppressing the immune response. Chemokines and cytokines released by CAFs, such as IL-6, attract circulating monocytes which are converted into myeloid-derived suppressor cells (MDSCs). MDSCs suppress T-cells and natural killer cell proliferation which inactivates the immune response and deters immunotherapy. Both Prostaglandin E2 (PGE2) and granulocyte-macrophage colony-stimulating factor (GM-CSF) have been implicated in the CAF immunosuppressive pathway, but a causal link has yet to be established. We hypothesized …
