Inhibitors of Viral Protein Synthesis

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...

Viruses with RNA Genomes

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...

RNA Interference

RNA Interference

RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

Retrovirus Life Cycles

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 retrovirus to...

Inhibitors Of Virion Release

Inhibitors Of Virion Release

Viral replication and dissemination rely on efficient mechanisms for host cell entry, genome replication, assembly, and release. Influenza viruses, such as types A and B, are negative-sense single-stranded RNA viruses with a segmented genome, that depend on two critical surface glycoproteins to carry out these processes: hemagglutinin (HA) and neuraminidase (NA). HA initiates infection by binding to sialic acid residues on the surface of host epithelial cells, facilitating receptor-mediated...

Summary

Interfering RNA (iRNA) are small RNAs that regulate gene expression. This review explores iRNA-virus interactions, including HIV strategies and potential therapeutic applications.

Area of Science:

Molecular Biology
Virology
Genetics

Background:

Interfering RNA (iRNA) are small RNA molecules that inhibit gene expression post-transcriptionally through sequence homology with messenger RNA (mRNA).
Viruses, including Human Immunodeficiency Virus (HIV), engage in complex interactions with iRNA pathways.
These interactions involve both viral and cellular iRNAs, influencing viral replication and host cell function.

Purpose of the Study:

To review the multifaceted interactions between iRNA and viruses, with a focus on HIV.
To elucidate HIV's strategies for manipulating iRNA pathways.
To discuss the implications of these interactions for viral latency, immune response, and potential therapeutic interventions.

Main Methods:

Review of existing literature on iRNA-virus interactions.

Analysis of viral (HIV) mechanisms for iRNA pathway manipulation.

Discussion of the impact of genetic variations in microRNA genes on HIV infection.

Main Results:

Four primary interaction types between iRNA and viruses are described: viral iRNA targeting viral RNA, viral iRNA downregulating cellular mRNA, cellular microRNA targeting viral RNA, and microRNA targeting cellular mRNA crucial for viral replication.
HIV employs strategies like Tat-mediated suppression of iRNA biosynthesis and TRBP sequestration to control iRNA pathways.
HIV can induce or suppress specific microRNAs, further manipulating host responses.

Conclusions:

The interplay between iRNA and viruses like HIV significantly impacts viral replication, latency, immune evasion, and pathogenicity.
Genetic polymorphisms in microRNA genes may influence HIV infection outcomes.
iRNA-based therapeutics hold potential for managing viral infections, including HIV.
