Overview

Drosophila has been used to model Epstein-Barr virus (EBV) infection, a common DNA virus of the herpes family. Although most people get infected with EBV at some point in their lives, it can cause several diseases, including infectious mononucleosis and some forms of cancer.

EBV DNA, when injected into young Drosophila adults, induces the fly immune deficiency (IMD) pathway, which controls the expression of most of the antimicrobial peptides in Drosophila. It is postulated that this IMD response is analogous to the enhanced expression of tumor necrosis factor-α observed in mice exposed to EBV DNA. This system has been used to investigate the possible role of EBV in prolonged inflammation of the digestive tract, such as in inflammatory bowel disease.

The viral lytic cascade of of Epstein-Barr virus (EBV) is induced by the two immediate early genes BZLF1 and BRLF1, which cooperate to induce expression of all downstream lytic genes. Drosophila models of Epstein-Barr virus infection have been created by introducing transgenic constructs of BRLF1 and BZLF1 (EBV\BRLF1, sometimes referred to as "R" and EBV\BZLF1, sometimes referred to as "Z"). These fly models have been used to study the interactions between host cellular proteins and the introduced BZLF1 and BRLF1 genes.

Symptoms and phenotype

Epstein-Barr virus (EBV), also known as human herpesvirus 4 (HHV-4), is a member of the herpes DNA virus family. It is one of the most common human viruses; most people get infected with EBV at some point in their lives. EBV spreads most commonly through bodily fluids, primarily saliva. EBV is associated with several diseases, including infectious mononucleosis and some forms of cancer.

Genetics

The Epstein-Barr viral lytic cascade is induced by the two immediate early genes BZLF1 and BRLF1, which cooperate to induce expression of all downstream lytic genes (Hutt-Fletcher, 2016; pubmed:27795426).
