The Role of Immune Cells in Chronic HBV Infection
نویسندگان
چکیده
Hepatitis B virus (HBV) infection is a major cause of chronic liver diseases that may progress to liver cirrhosis and hepatocellular carcinoma. Host immune responses are important factors that determine whether HBV infection is cleared or persists. After infection, viral replication occurs inside hepatocytes, and the secretion of infectious virions can take place at high rates for decades. Consequently, HBV DNA and viral proteins, like HBV early antigen (HBeAg) and HBV surface antigen (HBsAg), can be easily detected in serum. Chronic infection with HBV is the result of an ineffective antiviral immune response towards the virus. In this review, we discuss the role of immune cells in chronic HBV infection.

Current progress in the development of therapeutic vaccines for chronic hepatitis B virus infection
Chronic hepatitis B is still a major public health issue despite the successful prophylactic vaccination attempts. Chronicity of hepatitis B virus(HBV) is mainly due to its ability to debilitate host's immune system. Therefore, major measures have been taken to stop this process and help patients with chronic hepatitis B infection recover from their illness. While satisfactory results have been...

Background and purpose: Hepatitis B virus (HBV) is considered to be one of the most important etiological factors of liver complication around the world. Interactions of host immune responses with HBV have a crucial role in the outcome of the infection. IL12 is an important pro-inflammatory cytokine that stimulates natural killer cells and T-lymphocytes to produce IFN-γ, promotes T-helper...

Background and Aims: chronic HBV infection is one of the most common viral infections in worldwide which many factors such as genetic factors are involved in pathogenesis of disease. Gamma interferon (IFN-γ) and its receptor (INFGR) play a critical role in the immune response to HBV infection. Single nucleotide polymorphisms (SNPs) are effective on level of gene expression, The aim of thi...

Background: It has been arguedthat unprecedented degree of human leukocyte antigen (HLA) loci polymorphism within a population is requiredto avoid the devastating effects of infectious diseases. The present study was conducted to determine the associations between some of HLA classI genes and the outcome of hepatitis B virus (HBV) infection. Methods: Using sequential sampling method, 64 individ...
