Hematopathologic features of Epstein-Barr virus-induced human B-lymphoproliferation in mice with severe combined immunodeficiency. A model of lymphoproliferative diseases in immunocompromised patients.
The anatomical distribution, morphology, and clonality, of 'non-Hodgkin's lymphomas' in immunocompromised patients are usually distinctly different from NHL occurring in the general population. Mosier DE, Gulizia RJ, Baird SM, Wilson DB: Nature (London) 335:256, 1988 have described lymphoproliferative disease (LPD) of human B cell origin in mice with severe combined immunodeficiency (scid mice) after transfer of human peripheral blood mononuclear cells from Epstein-Barr virus-seropositive individuals. Reported herein is detailed information regarding the morphology, phenotypes, and clonality of LPD lesions in 10 of 18 scid mice that had developed LPD after transfer of peripheral blood mononuclear cells. These lesions were diffuse and monomorphic proliferations of immunoblastoid cells. They were invasive in their growth and often necrotic. Human B cell-related and activation-associated antigens were found on the LPD lesions, although the numbers of cells with the latter antigens were relatively small. Immunofixation electrophoresis for human immunoglobulins in sera of the majority of mice revealed oligoclonal populations, however, phenotypic and cytogenetic analyses showed no definite monoclonality. This scid mouse model is beneficial for understanding the early phases in the pathogenesis of LPD in immunocompromised patients.
