Abstract:
Gene-engineered T cells, represented by chimeric antigen receptor T cells (CAR-T cells), have achieved great success in hematological tumors, and gradually been applied in the clinical treatment of tumors. In 2017, two CD19-CAR products for hematological tumors were consecutively approved for marketing in America, and have shown powerful anti-tumor efficacy in non-solid tumor treatment. However, CAR-T cell therapy didn’t achieve expectant therapeutic efficacy in solid tumors due to complicated tumor microenvironment and restriction of surface tumor antigen. In addition, the cytotoxicity caused by off-target effects is more troublesome. To address these hurdles, more and more researchers have begun to explore new gene-edited T cells for solid tumor treatment, among which bispecific T cell engager T cell (BiTE T) has shown high anti-tumor efficacy in vitro evaluation and in vivo animal models and thus has attracted great attention. This review mainly discusses the current difficulties confronted by solid tumor treatment and the principles, characteristics and advantages of BiTE-T cell preparation.
