Abstract:
[Abstract] The most two advanced development in cancer immunotherapy: (1) Infusion with in vitro activated or gene-modified T cells; (2) Activation of suppressive immune cells by antibodies to exert cytotoxicity. The first one about gene-modified T cells is mainly referred to chimeric antigen receptor-T cells (CAR-T) that have shown the significant efficacy in some haematological malignancies.The latter one about immune checkpoint blockades takes effects on tumors with burden of gene mutations. For cancer patients, however,tumor microenvironment is suppressed highly more than the systemic immune. Normalizing or enhancing the local microenvironment by systemic activation of immune response may cause the overreaction in other normal tissues, even severe damage, for example interstitial lung diseases, acute myocarditis, and severe liver failure. This review summarizes the characterization and classification of tumor immune microenvironment, development of cancer treatment and immunotherapy, and elucidates the importance of targeting tumor immune microenvironment. The key strategy is pointed out to efficiently and precision target tumor immune microenvironment by using self-secreting antibody CAR-T cells (baize T cells), quickly enhancing the immune function in tumor microenvironment, which may eventually cure cancer.
