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...

Cytomegalovirus Disease

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

Coronavirus

Coronavirus

Coronaviruses, including the severe acute respiratory syndrome coronavirus (SARS-CoV), are enveloped viruses characterized by their single-stranded, positive-sense RNA genome and helical nucleocapsid structure. The hallmark of these viruses is their club-shaped spike (S) glycoproteins that protrude from the viral envelope, facilitating attachment to host cells. Typically, coronaviruses infect the upper respiratory tract, often causing mild or asymptomatic disease. However, certain strains like...

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...

Inhibitors Of Virion Release

Inhibitors Of Virion Release

Viral replication and dissemination rely on efficient mechanisms for host cell entry, genome replication, assembly, and release. Influenza viruses, such as types A and B, are negative-sense single-stranded RNA viruses with a segmented genome, that depend on two critical surface glycoproteins to carry out these processes: hemagglutinin (HA) and neuraminidase (NA). HA initiates infection by binding to sialic acid residues on the surface of host epithelial cells, facilitating receptor-mediated...

Background:

Hepatitis C virus (HCV) infection remains a significant global health concern.
Understanding the intricate mechanisms of HCV entry is crucial for developing effective antiviral therapies.

Purpose of the Study:

To review and summarize the current knowledge on the multifaceted process of HCV entry into host cells.
To highlight the sequential interactions of viral particles with host cell receptors and the subsequent internalization pathways.

Main Methods:

Review of existing scientific literature on HCV entry mechanisms.
Analysis of functional models detailing the early steps of the HCV life cycle.
Identification of key host cell factors and viral interactions involved in entry.

Main Results:

HCV entry is a slow, complex, multistep process involving sequential interactions with multiple host factors.
Initial attachment involves glycosaminoglycans and LDL receptor, followed by scavenger receptor class B type I, CD81, and claudin-1.
Internalization occurs via clathrin-mediated endocytosis, with fusion likely in early endosomes. EWI-2wint can inhibit viral entry by blocking CD81 interaction.

Conclusions:

The HCV entry pathway is well-defined, involving a cascade of specific receptor interactions.
Modulation of these entry factors, such as by EWI-2wint, presents potential therapeutic targets.
Further research into HCV entry mechanisms can inform the development of novel antiviral strategies.
