Retrovirus Life Cycles01:10

Retrovirus Life Cycles

48.8K
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...

Viral Mutations00:36

Viral Mutations

39.0K
A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

Size and Structure of Viral Genomes

507
Viral genomes exhibit remarkable diversity in size, structure, and composition, influencing their replication strategies and interactions with host cells. These genomes consist of either DNA or RNA and may be linear or circular. Additionally, they can be single-stranded or double-stranded, with each configuration affecting how the virus propagates within a host. RNA viruses, for instance, generally have smaller genomes than DNA viruses, a factor that contributes to their high mutation rates and...

Retroviruses

14.3K
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’...

Viruses with RNA Genomes01:29

Viruses with RNA Genomes

517
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...

Pulmonary Tuberculosis V01:28

Pulmonary Tuberculosis V

375
Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...

Summary
This summary is machine-generated.

Antiretroviral therapy (ART) controls human immunodeficiency virus (HIV) but is not a cure due to viral reservoirs. Strategies to eliminate ongoing replication are key to an HIV cure.

Area of Science:

  • Virology
  • Immunology
  • Infectious Diseases

Background:

  • Antiretroviral therapy (ART) significantly improves life expectancy for individuals with human immunodeficiency virus (HIV).
  • ART suppresses HIV replication, leading to undetectable plasma viral loads, but is not curative.
  • Viral persistence is attributed to latent reservoirs and ongoing replication, particularly in sanctuary sites with suboptimal drug penetration.

Purpose of the Study:

  • To investigate the reasons for the non-curative nature of ART in HIV infection.
  • To explore the role of ongoing HIV replication despite therapy.
  • To identify potential strategies for achieving an HIV cure.

Main Methods:

  • Review of existing literature on ART effectiveness and limitations.
  • Analysis of studies on viral load dynamics and drug penetration in sanctuary sites.
  • Examination of treatment intensification strategies and their impact on viral replication markers.

Main Results:

  • ART effectively reduces viral load but does not eliminate latent HIV reservoirs.
  • Ongoing HIV replication persists in sanctuary sites despite ART.
  • Treatment intensification, such as adding integrase inhibitors, may transiently increase viral by-products, suggesting a reduction in ongoing replication.

Conclusions:

  • Eliminating ongoing HIV replication is crucial for developing a curative strategy.
  • Further research is needed to confirm and target persistent viral replication.
  • Understanding and eradicating viral reservoirs and ongoing replication are essential steps towards an HIV cure.
