Cytotoxic T cells and helper T cells are primarily responsible for graft rejection as they recognize and attack foreign antigens on the graft tissue. B cells and other immune cells may play a secondary role in the rejection process. Natural killer cells are primarily involved in killing virus-infected or cancerous cells, while macrophages are involved in phagocytosing foreign substances. Plasma cells are differentiated B cells that secrete antibodies and are not directly involved in graft rejection.
