CD8A and breast carcinoma: It is also reported that depletion of TAM enhances CD8+ T‐cell‐mediated antitumour immunity under treatment with chemotherapy in a mouse model of breast cancer.19 In addition, results from other mouse models of breast cancer indicate that physical contact of TAM with tumour‐infiltrating CD8+ T cells suppresses full activation of T cells or their access to the tumour cells.20, 21 Therefore, TAM has been suggested as one of the important therapeutic targets to enhance the efficacy of immunotherapy.22
