WHY IMMUNE ESCAPE IS IMPORTANT Knowledge of the molecular virology of the hepatitis viruses and the responses they elicit has emphasised the importance of host immunity in resolving infection and mediating liver damage. Many viruses cause cytolytic infections in which viral replication occurs at the expense of host cell viability. However this is a shortsighted strategy for the virus as it prov...
Background and Aims: Torque teno virus (TTV) is a DNA virus that isolated from the serum of a Japanese patient without A-G transfusion-transmitted hepatitis and other etiology. TTV is detectable in plasma and peripheral blood mononuclear cells, different body fluids and secretions such as stools, saliva, semen, vaginal fluid. The genome exhibits high diversity that has enabled the determination...
Some studies have suggested that hepatitis E virus is more frequent in human immunodeficiency virus (HIV) patients and can progress to chronic infection. We aimed to determine the prevalence of hepatitis E virus antibodies and RNA in a series of 100 HIV-infected patients in Tehran, Iran, with comparison to 52 healthy HIV, hepatitis B and C-negative blood donors as controls. HIV-infected patient...
Co infection with hepatitis C virus and hepatitis D virus (HDV) is less common than that with HIV and HCV, although more attention has been given to HCV co infection as a result of its higher frequency of chronic disease. The present investigation was attempted to determine the exact prevalence of hepatitis B virus (HBV), hepatitis C virus (HCV) and hepatitis D virus (HDV) infection among liver...
Hepatitis a general term which refers to inflammation of the liver. It may result from various causes, both infectious ( viral, bacterial, fungal, and parasitic) noninfectious (alcohol, drugs, autoimmune diseases, metabolic diseases). The hepatitis B X protein (HBx) plays role in epigenetic regulation HBV replication. Real-time PCR has catalysed wider acceptance because it is more rapid, sensit...
ABSTRACT Three major hepatitis B virus (HBV) antigens include HBcAg, HBeAg and HBsAg. HBeAg is the extracellular form of HBcAg, and is seen almost exclusively in people who have circulating serum HBV DNA. Presence of HBsAg in serum indicates that the individual has contracted HBV infection. Chronic hepatitis HBeAg-negative/anti-HBe–p...
