Escaping high viral load exhaustion: CD8 cells with altered tetramer binding in chronic hepatitis B virus infection [PDF]

, 2002
Deletion, anergy, and a spectrum of functional impairments can affect virus-specific CD8 cells in chronic viral infections. Here we characterize a low frequency population of CD8 cells present in chronic hepatitis B virus (HBV) infection which survive in

Association of early age at establishment of chronic hepatitis B infection with persistent viral replication, liver cirrhosis and hepatocellular carcinoma: a systematic review. [PDF]

, 2013
Age at infection with hepatitis B virus (HBV) is a known risk factor for chronic HBV infection. However, in addition, there is some evidence that early age at infection further increases the risk of primary liver cancer beyond its association with ...

Interferon-α for Immune Modulation in Chronic Hepatitis B Toward Functional Cure

Viruses
Chronic hepatitis B (CHB) remains a major global health challenge, largely due to the persistence of covalently closed circular DNA (cccDNA) and impaired host immunity.

Prevention of Hepatitis B Vertical Transmission: Focus on Antenatal Antiviral Administration

Jurnal Penyakit Dalam Indonesia, 2016
Hepatitis B is one of the main cause of chronic liver disease, and potentially cause cirrhosis, liver failure and hepatocellular carcinoma in 15-40% population. Globally, 2 billion people are infected by Hepatitis B.

A novel monoclonal antibody targeting a conserved inner region of the hepatitis B virus envelope enables broad detection of immune escape variants

Virus Research
The detection of hepatitis B surface antigen (HBsAg) is fundamental for the diagnosis of chronic hepatitis B (CHB). However, current diagnostic assays that rely on antibodies targeting the conformational “a” determinant of HBsAg are frequently ...

Viral adaptation to host immune responses occurs in chronic hepatitis B virus (HBV) infection, and adaptation is greatest in HBV e antigen-negative disease [PDF]

, 2012
Hepatitis B virus (HBV)-specific T-cell responses are important in the natural history of HBV infection. The number of known HBV-specific T-cell epitopes is limited, and it is not clear whether viral evolution occurs in chronic HBV infection. We aimed to

Costs of Treatment, Follow-Up, and Complications of Chronic Hepatitis B and Hepatitis C Infections

Balkan Medical Journal, 2013
Background: Few studies have addressed the indirect costs of chronic hepatitis B and C, and none has assessed the real costs of these conditions, including indirect costs caused by loss of work, in Turkey. Aims: This study therefore analysed the costs of

Antiviral treatment alters the frequency of activating and inhibitory receptor-expressing natural killer cells in chronic Hepatitis B virus infected patients [PDF]

, 2012
Natural killer (NK) cells play a critical role in innate antiviral immunity, but little is known about the impact of antiviral therapy on the frequency of NK cell subsets.
