Abstract

Background: Severe combined immunodeficient (SCID) mice develop Epstein-Barr virus (EBV) containing human lymphoproliferative disease (LPD) tumors when reconstituted with human peripheral blood leukocytes (PBLs) from EBV-seropositive donors, but LPD tumors do not develop in the presence of immunosuppressive agents, such as cyclosporine A or corticosteroids. Methods: Therefore, LPD development in SCID mice was used as a model to explore the relationship among B cells, T cells, and EBV in vivo. SCID mice were engrafted with PBLs isolated by leukapheresis from a single EBV-seropositive donor. Purified populations of CD3+ lymphocytes (T cells) or CD19+ lymphocytes (B cells) were isolated and engrafted into SCID mice. Results: SCID mice engrafted with purified CD3+ lymphocytes (T cells) or CD19+ lymphocytes (B cells) did not develop LPD. In contrast, mice engrafted with purified B cells developed LPD if they were co-engrafted with purified T cells or if they were inoculated with infections EBV. Conclusions: This study confirms the requirement of T cells or active EBV infection in the development of LPD in animals engrafted with B cells latently infected with EBV. A greater understanding of the cellular and viral interactions leading to transformation and malignancy may allow the development of specific interventional therapies for malignancies in the immunosuppressed host.
