Summary
Hepatitis-B virus (HBV) infection affects millions, causing liver cancer. Current treatments require lifelong therapy, but new antiviral drugs and immunotherapies offer hope for a potential cure.
Area of Science:
- Hepatology
- Virology
- Immunology
Background:
- Hepatitis-B virus (HBV) infection is a significant global health issue, with 257 million chronic carriers and 1 million annual deaths, primarily from hepatocellular carcinoma (HCC).
- Current nucleotide analog treatments improve prognosis and reduce HCC risk but necessitate lifelong adherence.
- Understanding HBV replication and host immune responses is crucial for developing novel therapeutic strategies.
Purpose of the Study:
- To review the HBV replication cycle.
- To summarize current treatment modalities for HBV infection.
- To discuss emerging antiviral targets and therapies aimed at achieving an HBV cure.
Main Methods:
- Literature review of HBV replication, pathogenesis, and treatment strategies.
- Analysis of ongoing clinical trials and preclinical research on direct-acting antivirals (DAA) and immunomodulatory therapies.
- Synthesis of information on potential drug targets and novel antiviral approaches.
Main Results:
- HBV replication involves complex interactions between viral proteins and host cellular machinery.
- Nucleotide analogs offer long-term control but not a definitive cure.
- Combination therapies, including DAAs and immunomodulation, show promise for increased cure rates.
Conclusions:
- Achieving a functional cure for HBV remains a significant challenge.
- Further research into HBV's life cycle and host immunity is essential for identifying new therapeutic targets.
- Novel antiviral strategies and combination therapies represent the most promising path towards a curative treatment for chronic HBV infection.

01:10Retrovirus Life Cycles
46.1K
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...

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...

01:20Viral Replication: Lytic Cycle
51
Bacteriophages, or phages, are viruses that specifically infect bacteria. Among them, T-even bacteriophages, such as T4, exhibit a well-characterized lytic replication cycle in Escherichia coli (E. coli). This process ensures the rapid proliferation of the virus while ultimately leading to the destruction of the bacterial host.Attachment and DNA InjectionThe infection process begins with the recognition and binding of the T4 phage to the E. coli cell surface. Tail fibers of the phage...

01:16Viral Replication: Lysogenic Cycle
49
The lysogenic cycle is a crucial viral replication strategy that allows bacteriophages to persist within host cells without immediately destroying them. This process is primarily observed in temperate phages, such as bacteriophage lambda (λ), which infects Escherichia coli. The cycle allows the viral genome to persist across bacterial generations while keeping host cells viable.Integration of the Viral GenomeUpon infection, bacteriophage lambda attaches to the bacterial surface and injects...

62.3K
In contrast to the lytic cycle, phages infecting bacteria via the lysogenic cycle do not immediately kill their host cell. Instead, they combine their genome with the host genome, allowing the bacteria to replicate the phage DNA along with the bacterial genome. The incorporated copy of the phage genome is called the prophage. Some prophages can re-activate and enter the lytic cycle. This often occurs in response to a perturbation, such as DNA damage, but can also transpire in the absence of...
