T cell-redirected antigen-binding molecule for cells having immunosuppression function

摘要

The present invention provides an antigen-binding molecule that exhibits an excellent antitumor effect greater than exhibited by conventional antigen-binding molecules, as a result of the antigen-binding molecule: cross-linking T cells and cells having an immune response suppressing function; and inducing damage to the cells having the immune response suppressing function. The antigen-binding molecule includes: a domain (1) that binds to molecules expressed on the surface of cells having the immune response suppressing function; and a domain (2) that binds to a T cell receptor complex.
