Insights

New antivirals are needed to cure chronic hepatitis B (CHB) infection, as current treatments only suppress the virus and do not eradicate it. This review covers key developments in HBV replication inhibitors and immune regulators.

Area of Science:

  • Hepatology
  • Virology
  • Immunology

Background:

  • Chronic hepatitis B virus (CHB) infection is a significant global health issue, leading to cirrhosis and hepatocellular carcinoma (HCC).
  • While HBV vaccines reduce new infections, the burden of existing CHB remains substantial.
  • Current antiviral therapies, including nucleos(t)ide analogs like entecavir (ETV) and tenofovir disoproxil fumarate (TDF), effectively suppress viral replication but require lifelong treatment and cannot eliminate the virus.

Purpose of the Study:

  • To review the latest advancements in antiviral therapies for chronic hepatitis B.
  • To highlight novel strategies targeting HBV replication and host immune responses for a potential cure.

Main Methods:

  • Literature review of recent developments in hepatitis B antivirals.
  • Analysis of HBV replication cycle inhibitors.
  • Examination of host immune-modulating agents for HBV treatment.

Main Results:

  • Current first-line treatments (ETV, TDF) offer viral suppression but present challenges like cost and long-term adherence.
  • No existing therapies can eradicate the intracellular HBV, indicating an unmet medical need.
  • Emerging strategies focus on inhibiting viral replication and restoring host immunity.

Conclusions:

  • There is a critical need for novel therapeutic strategies to achieve a functional cure for chronic hepatitis B.
  • Inhibitors of HBV replication and host immune regulators represent promising avenues for future HBV cure development.

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.

Inhibitors of Viral Protein Synthesis01:30

Inhibitors of Viral Protein Synthesis

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...

Retrovirus Life Cycles01:10

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...

Viruses with RNA Genomes01:29

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...
