Summary
Chronic hepatitis B virus (HBV) infection affects 350 million globally. Current treatments are insufficient for a cure due to persistent viral DNA, necessitating novel combination therapies for eradication.
Area of Science:
- Hepatology
- Virology
- Pharmacology
Background:
- Chronic hepatitis B virus (HBV) infection impacts 350 million worldwide, posing a significant public health concern.
- Current treatments, including nucleos(tide) analogues (NUCs) and interferon alpha (IFNα), aim to prevent disease progression but rarely achieve a cure.
- HBV cure is challenging due to the persistence of covalently closed circular DNA (cccDNA) within infected cells.
Purpose of the Study:
- To review the current landscape of hepatitis B virus (HBV) drug research.
- To highlight therapeutic agents with the highest potential for eradicating chronic HBV infection.
- To summarize the state-of-the-art in HBV drug development, including in vitro and clinical data.
Main Methods:
- Comprehensive literature review of HBV drug research.
- Analysis of in vitro studies on novel antiviral agents.
- Evaluation of clinical trial data for emerging HBV therapeutics.
Main Results:
- Current therapies require lifelong treatment and surveillance due to frequent reactivation and incomplete elimination of hepatocellular carcinoma (HCC) risk.
- Novel therapeutic strategies are being developed, likely requiring combination approaches.
- Promising agents include immune modulators, gene expression/replication inhibitors, and cccDNA-targeting drugs.
Conclusions:
- Eradication of chronic HBV infection remains a significant challenge, unmet by current standard-of-care therapies.
- A combination of diverse therapeutic strategies targeting viral persistence and host immunity is essential for achieving a functional cure.
- Ongoing research into novel drug candidates offers hope for improved treatment outcomes and potential eradication of HBV.

34
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.

01:30Inhibitors of Viral Protein Synthesis
16
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...

01:10Retrovirus Life Cycles
50.5K
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...

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
