Dual-signal independent chimeric antigen receptors (dsCAR) and uses thereof

The invention relates to chimeric antigen receptors (CAR), particularly relates to dual-signal independent chimeric antigen receptors (dsCAR), and also relates to immune response cells of the dual-signal independent chimeric antigen receptors (dsCAR) and uses of the immune response cells in preparation of drugs for treatment of malignant tumor and virus infected diseases. In detail, the dual-signal independent chimeric antigen receptors (dsCAR) can respectively identify two different family antigens of tumor cells and can respectively transmit two T-cell-activation related signals. One of the CAR can transmit a first T-cell-activation related signal by combing a ligand of a tumor specific antigen or a tumor-associated antigen to decide T-cell killing specificity, and the other CAR can transmit a second T-cell-activation related signal by combing a ligand of a membrane receptor (such as EGFR (epidermal growth factor receptor) family protein) widely expressed by the tumor cells to promote T cell activation, proliferation and survival. The dual-signal independent chimeric antigen receptors (dsCAR) can avoid the potential safety problems on the basis of maintaining curative effects of second generation and third generation CAR.
