Polyclonal activation of B-lymphocytes accompanies many retroviral infections. Friend derived murine immunosuppressive virus (Fd-MIV) is a non-defective murine retrovirus which was isolated from T-helper cells from mice infected with the acute transforming retrovirus Friend leukaemia complex (FLC). In contrast to FLC, Fd-MIV does not induce acute transformation of lymphoid and erythroid cells but causes immunosuppression and lymphadenopathy in adult NMRI mice. The effect of Fd-MIV infection on B-lymphocytes was studied. Fd-MIV infection led to a persistent hypergammaglobulinemy with a significant increase in the level of circulating IgG, IgM and immune complexes. In the spleen and lymph nodes, B-lymphocyte proliferation was found. Parallel to the development of hypergammaglobulinemy, autoantibodies to a variety of nuclear and other autoantigens was detected. In conclusion, the Fd-MIV infection leads to a B-lymphocyte dysfunction that has many parallels with AIDS. Furthermore, the Fd-MIV infection seems to represent an example of an autoimmune condition caused by an exogenous infectious agent.

D007075	Immunoglobulin M	A class of immunoglobulin bearing mu chains (IMMUNOGLOBULIN MU-CHAINS). IgM can fix COMPLEMENT. The name comes from its high molecular weight and originally was called a macroglobulin.	Gamma Globulin, 19S,IgM,IgM Antibody,IgM1,IgM2,19S Gamma Globulin,Antibody, IgM
D007165	Immunosuppression Therapy	Deliberate prevention or diminution of the host's immune response. It may be nonspecific as in the administration of immunosuppressive agents (drugs or radiation) or by lymphocyte depletion or may be specific as in desensitization or the simultaneous administration of antigen and immunosuppressive drugs.

D008213	Lymphocyte Activation	Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.
