A syndrome characterized by lymphadenopathy, hypergammaglobulinemia, and immunodeficiency develops in C57BL/6 mice inoculated with LP-BM5 murine leukemia viruses. By studying the number and antigenic specificity of B cells activated in the course of this disease, we found that a series of reproducible changes in the humoral immune system were induced by retroviral infection. The rate of B cell proliferation and the proportion of B cells activated to secrete Ig increased by nearly 10-fold at 4 wk post inoculation. B cells producing antibodies reactive with a panel of three conventional Ag and five autoantigens were stimulated simultaneously and proportionally to secrete, demonstrating that such activation was polyclonal in nature. At 12 wk post infection, the number of Ig-secreting B cells continued to rise and significant hypergammaglobulinemia developed. At 16 wk post infection, immunostimulation gave way to immunosuppression, as evidenced by a slight decline in the number of Ig-secreting lymphocytes and a sharp reduction in the concentration of serum antibody. At this time, the B cell repertoires of infected mice diverged markedly from those of uninfected animals. These changes are comparable to those found in some patients infected with HIV, and provide a useful model to study the association between retroviral infection and regulatory abnormalities of the humoral immune system.
