Since immunosuppressive cells in the TME and spleen including myeloid‐derived suppressor cells (MDSCs) and tumor‐associated macrophages (TAMs) also express the IL‐4R, we hypothesized that selective depletion of IL‐4R‐bearing cells in TNBC would result in the direct killing of tumor cells and the depletion of immunosuppressive cells and lead to an enhanced antitumor response. Here, IL4R is linked to neoplasm.
