Abstract

Many details in the expression pattern of Epstein-Barr virus (EBV)- encoded proteins, their role in blast and growth transformation in infected B lymphocytes are known, but 'black holes' still exist. The two main types of virus-B lymphocyte interactions are denoted as Type I and Type III. These are characterized by the difference in the EBV protein expression which is related to the phenotype of the cell. The difference was first detected in comparisons between Burkitt lymphoma cells (BL) and lymphoblastoid cell lines, LCLs, which arise from normal B lymphocytes after experimental infection and are growth transformed by EBV. A third type of interaction can be seen in B-CLL cells which carry the EBV receptor CD21 and can be thus infected with the virus in vitro. The infected cells express the EBV-encoded proteins with a pattern which is different from the above mentioned two types, in that they express the nuclear proteins but not the membrane localized LMP-1. Importantly, the infected B-CLL cells do not enter DNA synthesis and they do not growth transform. Normal lymphocytes with similar expression pattern have been seen in analysis of the lymphoreticular tissues of patients which responded to the primary EBV infection with development of the infectious mononucleosis symptoms.
