Cytotoxic T cells and helper T cells are mainly responsible for graft rejection. These cells recognize foreign antigens on the graft and mount an immune response to destroy it. B cells and plasma cells are involved in antibody-mediated immune responses but are not as important in graft rejection. Natural killer cells and macrophages play a role in innate immunity but are not as specific in recognizing foreign antigens as T cells.
