Seropidemiology of Epstein – Barr virus infection among asymptomatic
Introduction: Epstein – Barr virus (EBV) is a herpesvirus which establishes a persistent life-long infection in over 95% of adults world wide. Infection is usually asymptomatic but the virus is associated with a variety of disease, including nasopharyngeal carcinoma (NPC), Burkitt’s lymphoma (BL), Multiple sclerosis MS, EBV-associated B-cell lymphoproliferative disease (BLPD), Hodgkin and non...
متن کاملMechanism of action of glycyrrhizic acid in inhibition of Epstein-Barr virus replication in vitro.
We report here that glycyrrhizic acid (GL), a component of licorice root (Glycyrrhiza radix), is active against EBV replication in superinfected Raji cells in a dose-dependent fashion. The IC(50) values for viral inhibition and cell growth were 0.04 and 4.8mM, respectively. The selectivity index (ratio of IC(50) for cell growth to IC(50) for viral DNA synthesis) was 120. Time of addition experi...
متن کاملEpstein-Barr virus infection mechanisms
Epstein-Barr virus (EBV) infection occurs by distinct mechanisms across different cell types. EBV infection of B cells in vitro minimally requires 5 viral glycoproteins and 2 cellular proteins. By contrast, infection of epithelial cells requires a minimum of 3 viral glycoproteins, which are capable of interacting with one or more of 3 different cellular proteins. The full complement of proteins...
متن کاملInnate immune responses against Epstein Barr virus infection.
EBV persists life-long in >95% of the human adult population. Whereas it is perfectly immune-controlled in most infected individuals, a minority develops EBV-associated diseases, primarily malignancies of B cell and epithelial cell origin. In recent years, it has become apparent that the course of primary infection determines part of the risk to develop EBV-associated diseases. Particularly, th...
متن کاملAnimal models of Epstein Barr virus infection.
Epstein Barr virus (EBV) was the first human tumor virus to be described. Despite its discovery now more than fifty years ago, immune control of this virus is still not very well understood and no vaccine is available. This knowledge gap is due in part to the lack of a preclinical small animal model which can faithfully recapitulate EBV infection and immune control, and would allow testing of E...
