Summary
RNA interference (RNAi) is a natural defense against viruses in many organisms. This review explores how viruses and RNAi interact, highlighting RNAi
Area of Science:
- Molecular Biology
- Virology
- Immunology
Background:
- RNA interference (RNAi) regulates gene expression and acts as an antiviral defense in plants, insects, and nematodes.
- Evidence suggests RNAi also functions as an antiviral mechanism in mammalian cells.
- Viruses interact with host cell machinery, including RNAi pathways, for replication or evasion.
Purpose of the Study:
- To summarize recent findings on virus-RNAi interactions.
- To discuss RNAi-based antiviral therapy approaches.
Main Methods:
- Literature review of virus-RNAi interactions.
- Analysis of viral strategies to manipulate RNAi pathways.
- Overview of RNAi-based therapeutic strategies against viral infections.
Main Results:
- Viruses can inhibit RNAi pathways or exploit them for replication.
- Viruses encode proteins/RNAs to suppress host RNAi or silence host genes.
- Induced RNAi shows promise as an antiviral therapy.
Conclusions:
- The interplay between viruses and RNAi is complex, involving both defense and exploitation.
- Targeting viral interactions with RNAi pathways offers potential for novel antiviral therapies.

01:23RNA 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...

02:15Experimental RNAi
RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...
01:29Viruses 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...
02:30siRNA - Small Interfering RNAs
Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the ATP-dependent...

01:25Inhibitors 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...
