Lymphoma development was studied in scid mice injected i.p. with PBMC from EBV-positive donors. Most injected mice developed oligo/monoclonal B-cell tumors within 4 months after the inoculation; EBV genome was found in tumor cells. Removal of T lymphocytes from the injected cell populations prevented lymphoma development in all mice, suggesting that T-cell-derived factors are involved in the expansion of the latently EBV-infected B-cell population within the immunodeficient host.
