Patent ID: 11993662

Abstract:
The present invention provides a general sequence of chimeric antigen receptor (CAR) and an application thereof, The hinge domain in the general sequence includes hinge domain V-5, hinge domain V-4-5, hinge domain V-3-4-5, hinge domain V-2-3-4-5 or hinge domain V-1-2-3-4-5. The CAR constructed by using the general sequence of the chimeric antigen receptor of the present invention can significantly improve the antigen-specific immune response of CAR-T cells, enhance the sensitivity of CAR-T cells and resist exhaustion, so as to enhance the therapeutic effect of CAR-T cells and enhance the therapeutic effect of anti-tumor agents. At the same time, the CAR containing the general sequence of the present invention is suitable for transfection of immune cells such as T cells and NK cells, and can be broadly applied to tumor therapy.
