摘要:
Disclosed are compositions and methods for preventing graft versus host disease (GVHD) in subjects receiving donor cells. In particular, chimeric antigen receptor (CAR) polypeptides are disclosed that can be used with adoptive cell transfer to suppress alloreactive donor cells. Therefore, also disclosed are methods of suppressing alloreactive donor cells in a subject receiving transplant donor cells that involves adoptive transfer of the disclosed regulatory T cells engineered to express the disclosed CARs. Also disclosed is a method of preventing rejection of off-the-shelf therapeutic immune effector cells, such as CAR-T cells, in a subject that involves administering to the subject an effective amount of a regulatory T cell genetically modified with a disclosed CD83-specific CAR.
