Abstract:
:Epstein-Barr virus (EBV)-positive B-cell lymphoproliferative disease (BLPD)-like lesions develop in severe combined immunodeficient (SCID) mice inoculated with peripheral blood mononuclear cells (PBMCs) from EBV-seropositive donors. We used this model to investigate the pathogenesis of EBV-associated BLPD. Tumour incidence fell from 81% to 11% when only B cells were inoculated, suggesting a key role for T cells in tumour formation. This was further underlined by the reduction in tumour incidence from 76% to 7% when PBMCs were depleted of CD4 positive (+ve) helper T cells. Tumour outgrowth was also reduced when PBMC were depleted of CD8 +ve, CD45RA +ve or CD45RO +ve T cells. The majority of PBMC-derived tumours analysed by reverse transcriptase-polymerase chain reaction (RT-PCR) expressed mRNA for interleukin (IL) 2, 4, 6, 10 and interferon (IFN) gamma. This is the cytokine pattern seen in activated T cells and includes B-cell growth factors. In situ hybridization studies confirmed that the tumour cells themselves express the growth factors, which is consistent with autocrine-stimulated tumour growth. Our results suggest the following sequence of events: (1) T cells are essential for the initial outgrowth of tumorigenic EBV +ve B cells in vivo; (2) the neoplasm sustains its growth in an autocrine, cytokine-stimulated manner; and (3) established tumours become independent of T-cell help.
