Clonal outgrowths of T and B cells in SCID mice reconstituted with cells from mice with MAIDS.
Murine acquired immunodeficiency syndrome (MAIDS), induce in mice by a defective murine retrovirus (BM5def), is characterized by development of severe immunodeficiency and polyclonal lymphoid proliferation which progress to yield oligoclonal populations of T and B cells. Oligoclonal populations transferred to SCID mice grew as clonal CD4+ T cell or B cell lineage transplants having one or more unique clonal integrations of BM5def. In some cases, spleens of single donor mice were shown to contain both B cell and T cell lineage clones that could be transferred individually after separation and were clonally unrelated. Successful transplants were obtained from oligoclonal populations as early as 63 days after infection. Mouse strains both sensitive or moderately resistant to MAIDS yielded clonal transplants.
