Hepatitis

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...

Viral Hepatitis I: Introduction

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...

Viruses with RNA Genomes

Viruses with RNA Genomes

RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

Retrovirus Life Cycles

Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the retrovirus to...

Size and Structure of Viral Genomes

Size and Structure of Viral Genomes

Viral genomes exhibit remarkable diversity in size, structure, and composition, influencing their replication strategies and interactions with host cells. These genomes consist of either DNA or RNA and may be linear or circular. Additionally, they can be single-stranded or double-stranded, with each configuration affecting how the virus propagates within a host. RNA viruses, for instance, generally have smaller genomes than DNA viruses, a factor that contributes to their high mutation rates and...

Retroviruses

Retroviruses

Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...

Summary

Viral hepatitis, caused by hepatitis B and C viruses, leads to chronic liver inflammation. Apoptosis, a cell death process, plays a key role in viral hepatitis pathogenesis and may contribute to liver cancer development.

Area of Science:

Hepatology
Virology
Immunology

Background:

Viral hepatitis, specifically B and C, causes persistent liver inflammation.
Chronic inflammation can lead to fibrosis, cirrhosis, and hepatocellular carcinoma (HCC).
Apoptosis is a key antiviral defense mechanism in the liver.

Purpose of the Study:

To provide an overview of apoptosis in the pathogenesis of chronic viral hepatitis.
To explore the role of viral proteins in modulating apoptosis.
To discuss the complex mechanisms of liver injury in viral hepatitis.

Main Methods:

Pathomorphologic studies examining hepatocyte apoptosis.
Comparative analysis of apoptosis in infected vs. healthy subjects.
Review of existing data on viral protein interactions with apoptosis.

Main Results:

Increased hepatocyte apoptosis observed in chronic hepatitis B and C patients.
Evidence suggests viral proteins can modulate apoptosis.
Apoptosis inhibition may be a viral survival strategy linked to HCC.

Conclusions:

Apoptosis is significantly involved in the pathogenesis of chronic hepatitis B and C.
Viral modulation of apoptosis may contribute to disease progression and HCC.
Understanding these complex mechanisms is crucial for managing viral hepatitis.
