Insights

Hepatitis B virus (HBV) infection is a global health issue. Understanding HBV

Area of Science:

  • Hepatology
  • Virology
  • Molecular Biology

Background:

  • Hepatitis B virus (HBV) poses a significant global health challenge, causing millions of infections worldwide.
  • HBV, a hepadnaviridae family member, is a leading cause of acute and chronic liver disease, including cirrhosis and hepatocellular carcinoma (HCC).

Purpose of the Study:

  • To review current knowledge on Hepatitis B virus intracellular transport and genome repair.
  • To identify potential therapeutic targets for HBV cures by understanding its molecular mechanisms.

Main Methods:

  • Literature review of recent studies on HBV intracellular trafficking.
  • Comparative analysis of HBV genome repair with other nuclear-replicating viruses.

Main Results:

  • HBV exhibits complex intracytoplasmic and nuclear transport pathways.
  • Genome repair mechanisms in HBV are being elucidated, offering insights into viral persistence.

Conclusions:

  • Understanding HBV's intracellular journey and genome repair is vital for novel therapeutic strategies.
  • Combined approaches using antivirals and immune modulators may lead to potential cures for chronic HBV infection.

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...

Intracellular Movement of Viruses and Bacteria

Intracellular bacteria and viruses often comprise a group of highly infectious pathogens that can cause several diseases. Bacterial pathogens include those belonging to the genus Rickettsia responsible for conditions such as rocky mountain spotted fever and the Mediterranean spotted fever; Chlamydia, a genus responsible for a sexually transmitted disease; Coxiella burnetii, an agent responsible for Q fever. Viral pathogens include vaccinia—a poxvirus, and herpes simplex virus—a...

Homologous Recombination02:31

Homologous Recombination

The basic reaction of homologous recombination (HR) involves two chromatids that contain DNA sequences sharing a significant stretch of identity. One of these sequences uses a strand from another as a template to synthesize DNA in an enzyme-catalyzed reaction. The final product is a novel amalgamation of the two substrates. To ensure an accurate recombination of sequences, HR is restricted to the S and G2 phases of the cell cycle. At these stages, the DNA has been replicated already and the...

Nucleotide Excision Repair

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

Retroviruses02:33

Retroviruses

Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...

Long-patch Base Excision Repair

Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:
