The major histocompatibility complex (MHC) of the mouse can be genetically divided into several regions specialized to performing specific functions. Thus the class I regions (K and D) code for antigens that activate effector (killer) T cells, class II region (I) for antigens causing T‐cell proliferation, and class III regions (s) for complement components. A strong case is made for the theory that the division of labor within the MHC is not absolute. Evidence is presented that class I antigens can sometimes cause as strong T‐cell proliferation as class II antigens; that class II antigens can generate effector T cells; and that class I antigens may be involved in the immune response to some antigens. The fact that different regions can perform similar functions argues for the unity of the MHC genes.
