Sero-prevalence and risk factors for hepatitis B virus infection among health care workers in a tertiary hospital in Uganda. [PDF]

open access: yes, 2010
BACKGROUND: Hepatitis B virus (HBV) infection is a global public health challenge. Prevalence of current hepatitis B virus infection in the general population in Uganda is about 10%.

Tracking Virus-Specific CD4+ T Cells during and after Acute Hepatitis C Virus Infection [PDF]

open access: yes, 2007
Background. CD4+ T cell help is critical in maintaining antiviral immune responses and such help has been shown to be sustained in acute resolving hepatitis C.

Evidence of viral adaptation to HLA class I-restricted immune pressure in chronic hepatitis C virus infection [PDF]

open access: yes, 2006
Cellular immune responses are an important correlate of hepatitis C virus (HCV) infection outcome. These responses are governed by the host's human leukocyte antigen (HLA) type, and HLA-restricted viral escape mutants are a critical aspect of this host ...

Host genetic factors in hepatitis B infection, liver cancer and vaccination response: a review with a focus on Africa. [PDF]

open access: yes, 2012
The disease burden due to hepatitis B virus (HBV) infection remains significant; 350 million people are infected world-wide, and around half a million deaths each year are due to HBV-related liver disease and hepatocellular carcinoma (HCC).

Modulation of the CD8+-T-cell response by CD4+ CD25+ regulatory T cells in patients with Hepatitis B virus infection [PDF]

open access: yes, 2005
CD4+ CD25+ regulatory T cells have been shown to maintain peripheral tolerance against self and foreign antigens. In this study we analyzed the effect of circulating CD4+ CD25+ T cells on CD8+-T-cell responses of patients with chronic and resolved ...

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

open access: yes, 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

Seroepidemiology of hepatitis B virus in Addis Ababa Ethiopia: transmission patterns and vaccine control [PDF]

open access: yes, 2003
A community-based seroepidemiological survey of Addis Ababa, Ethiopia was conducted in 1994 to inform on the transmission dynamics and control of hepatitis B virus (HBV) infection.

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]

open access: yes, 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

An extracellular humanized IFNAR immunocompetent mouse model for analyses of human interferon alpha and subtypes

open access: yesEmerging Microbes and Infections
Type I interferons (IFN-Is) have key roles in immune defense and treatments for various diseases, including chronic hepatitis B virus (HBV) infection.
