Epstein-Barr Virus Background

Epstein-Barr virus (EBV), officially known as human gamma herpesvirus 4, is a DNA virus classified on Herpesviridae family, Gamma herpesvirinae subfamily, Lymphocrytovirus genus. It is the first human virus directly related to lymphoid and epithelial tumorigenesis. Most people become infected with EBV during their lives. Primary infection usually leads to infectious mononucleosis (glandular fever), but the virus can also lurk in B lymphocytes and once reactivated, it will be associated with more serious diseases such as Burkitt's lymphoma, nasopharyngeal carcinoma and Hodgkin's disease.

Virus Classification of EBV

Many attempts have been made to classify EBV according to clinical or epidemiological information. Initially, EBV was divided into two types according to EBNA2 and EBNA-3A, -3B and -3C genes: EBV type 1 (EBV-1) and EBV type 2 (EBV-2) (type A and type B). One of the clinical differences between them is that EBV-1 can transform B cells into lymphoblastic cell lines (LCL) more effectively than EBV-2. The geographical distribution of EBV type shows that EBV-1 is the most popular type in the world, mainly distributed in Europe, Asia, North and South America. In contrast, the EBV-2 is more common in Alaska, Papua New Guinea and Central Africa, and in countries such as Kenya. This classification method is the most widely accepted at present.

Structure of EBV

The genome of EBV is composed of linear double-stranded DNA of about 170 kb in length, including about 80 possible coding regions (CDS), a series of repeat regions. In some cancers, large insertion and deletion regions were found in biopsies and cancer cell line cultures. Like other herpesviruses, EBV is a virus with a toroid-shaped protein core, wrapped in DNA, with a 162 capsid nucleocapsid, a protein tegument between the nucleocapsid and the envelope, and with an outer envelope with external virus-encoded glycoprotein (gp) spike. During EBV infection, different envelope gps induce virus entry.

When the virus enters the B cells, gp350 binds to the type 2 complement receptor (CD21) on the B cell. Through the complex of gp42, gH and gL, the fusion of cell membrane and virus envelope is induced by MHC (major histocompatibility complex) II on the B cell. In the process of virus entry into epithelial cells, BMRF2 binds to β1-integrin on epithelial cells, and the complex of gH and gL promotes membrane fusion. Gp110 improves the efficiency of EBV infection on B cells and epithelial cells.
