Summary
Chronic hepatitis B virus infection affects 300 million globally, risking liver cancer. New strategies aim for a cure by targeting the virus and boosting immunity, moving beyond current non-curative treatments.
Area of Science:
- Hepatology and Virology
- Immunology
- Oncology
Background:
- Hepatitis B virus (HBV) persistently infects approximately 300 million people worldwide.
- Chronic HBV infection is a leading cause of liver cirrhosis and hepatocellular carcinoma (HCC).
- Current antiviral therapies offer limited efficacy, focusing on viral suppression rather than cure.
Purpose of the Study:
- To review novel therapeutic strategies for chronic hepatitis B.
- To evaluate approaches aimed at improving cure rates and eliminating infected hepatocytes.
- To assess the clinical feasibility and translational potential of emerging HBV treatments.
Main Methods:
- Review of recent scientific literature on HBV cure strategies.
- Analysis of approaches targeting different stages of the HBV life cycle.
- Evaluation of methods to enhance the host antiviral immune response.
Main Results:
- Several promising strategies are under investigation, including direct-acting antivirals and immunotherapies.
- Targeting viral proteins and enhancing T-cell responses show potential for viral clearance.
- Combination therapies may be necessary to achieve high cure rates.
Conclusions:
- Significant progress is being made towards curative therapies for chronic hepatitis B.
- Emerging strategies offer hope for eliminating infected cells and achieving functional cures.
- Further research and clinical trials are essential to translate these findings into effective treatments.

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.

01:10Retrovirus Life Cycles
50.7K
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...

01:17Hepatic Drug Excretion: Enterohepatic Cycling
3.4K
Enterohepatic cycling involves the active secretion of drugs and their metabolites into the bile via transporters in the canalicular membrane of hepatocytes. This secretion is an integral part of the digestive process, releasing these substances into the gastrointestinal (GI) tract.
Post-release drugs and metabolites can be reabsorbed into the body from the intestine. For conjugated metabolites like glucuronides, reabsorption requires enzymatic hydrolysis by intestinal microflora. This...

1.4K
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...

01:30Inhibitors of Viral Protein Synthesis
32
Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...
