Chimeric antigen receptor (CAR) is generated by fusing a cancer-specific antibody's antigen recognition site with costimulatory molecules such as CD28 and CD3ζ. T cells transduced with CAR recognizes cancer-specific antigens and kill cancer cells. The effect of CD19-targeted CAR T cells on B-cell hematologic cancer is surprising and has already been approved in many countries including Japan. More targets for several kinds of cancers are being searched now. We have also shown that CAR T cells specific for activated integrin β7 are highly effective for multiple myeloma in pre-clinical tests.
