Hepatitis B virus biology and life cycle - ScienceDirec

Hepatitis B virus is a member of the Hepadnaviridae family and responsible for causing acute and chronic hepatitis in humans. The current estimates of people chronically infected with the virus are put at 250 million worldwide. Immune-mediated liver damage in these individuals may lead to the development of cirrhosis and hepatocellular carcinoma later in life The life cycle of hepatitis B virus is complex. Hepatitis B is one of a few known pararetroviruses: non-retroviruses that still use reverse transcription in their replication process. The virus gains entry into the cell by binding to NTCP on the surface and being endocytosed.Because the virus multiplies via RNA made by a host enzyme, the viral genomic DNA has to be transferred to the cell. The overall structure of hepatitis B virus (HBV) is briefly described, followed by a discussion of its infectious life-cycle. This starts with entry into the cell, transport of the partially-double stranded viral DNA to the nucleus, its uncoating and repair by cellular polymerases to produce the covalently-closed circular DNA

Hepatitis B virus (HBV) is a major human health problem, with more than 240 million people chronically infected with the virus worldwide and at least 780,000 people dying each year from HBV-related liver diseases such as cirrhosis and liver cancer ().There is no known cure for chronic HBV (CHB) infection, and the preventative vaccines that are currently in use have no impact on existing.

Hepatitis B virus alone can cause cirrhosis or liver cancer. When combined with the hepatitis D virus, the development of these diseases happens more frequently and more rapidly, he says Reproductive Cycle of a Hepatitis B in a Host Cell Although a DNA virus, Hepatitis B virus uses a RNA proviral intermediate that has to be copied back to DNA for replication. The copying of RNA to DNA is not a normal function of an uninfected cell but is found in retroviruses that also have an RNA genome and a DNA intermediate that gets integrated into host cell chromosomes The latter contains integral membrane proteins of three sizes, collectively known as hepatitis B surface antigen, and adopts multiple conformations in the course of the viral life cycle. The nucleocapsid conformation depends on the reverse transcription status of the genome, which in turn controls nucleocapsid interaction with the envelope proteins for virus exit Abstract Hepatitis B virus (HBV) is a human pathogen, causing the serious liver disease.

Chronic Hepatitis B Virus Infection. A chronic hepatitis B infection means that the immune system is not able to get rid of the virus within six months after infection. In other words, the virus continues to reproduce in the person's liver for several months or years after infection More than 500 million people are persistently infected with hepatitis B virus (HBV) and/or hepatitis C virus (HCV) and are at a risk of developing chronic hepatitis, cirrhosis, and liver cancer. The absence of robust cell culture systems for both viral infections limits the understanding of the virus lifecycle and pathogenesis required for the development of vaccine and antivirals Hepatitis B virus (HBV) causes transient and chronic infec-tions of the liver. Transient infections may produce serious illness, and approximately 0.5% terminate with fatal, fulminant hepatitis. Chronic infections may also have serious conse-quences: nearly 25% terminate in untreatable liver cancer (10)

ABSTRACT: During the hepatitis B virus (HBV) life cycle, capsid assembly and disassembly must ensure correct packaging and release of the viral genome. Here we show that changes in the dynamics of the core protein play an important role in regulating these processes. The HBV capsid assembles from 120 copies of the core protein homodimer Hepatitis D virus (HDV) is the most pathogenic hepatitis virus and it requires hepatitis B virus (HBV) for its life cycle. Compared to individuals infected with HBV alone, HBV/HDV coinfected people have an even higher incidence of HCC

In this review, we discuss recent advances that have contributed to a better understanding of HBV biology Hepatitis B virus alone can cause cirrhosis or liver cancer. When combined with the hepatitis D virus, the development of these diseases happens more frequently and more rapidly, he says. In the course of this research, Professor Labonté's team made an interesting discovery: some autophagy proteins travel outside their usual area With the advent of the discoveries of the hepatitis B virus (HBV) in the 1960s by Baruch Blumberg and colleagues (Bayer et al. 1968) and the hepatitis A virus (HAV) in the early 1970s by Feinstone et al. (1973), it became evident, surprisingly, that most transfusion-associated hepatitis cases were caused by neither of these viral infections (Prince et al. 1974; Feinstone et al. 1975), thus. Viral replication occurs in the nucleus of primary hepatocytes using a double-rolling circle mechanism. New virions can be assembled only in the presence of hepatitis B virus. The stages of the viral life cycle, including replication, assembly, and transport, depend on the ratio of small to large delta antigen
