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 Interference01:23

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...

Leaky Scanning02:28

Leaky Scanning

During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA.  Marilyn Kozak discovered that the sequence RCCAUGG (where R stands for...

Mammals fight viral infections using RIG-I-like receptors (RLRs). These sensors detect viral RNA, distinguishing between healthy and infected cells to trigger crucial antiviral defense mechanisms.

Area of Science:

  • Immunology
  • Molecular Biology
  • Virology

Background:

  • Mammalian cells possess defense mechanisms against viral infections.
  • Virus-sensing receptors initiate host responses upon pathogen detection.
  • RIG-I-like receptors (RLRs) are key intracellular sensors of viral RNA.

Purpose of the Study:

  • To review recent advancements in understanding RLR function.
  • To elucidate how RLRs differentiate between self and viral RNA.
  • To highlight the role of RLRs as accurate virus invasion sensors.

Main Methods:

  • This review synthesizes current research findings.
  • Focuses on molecular mechanisms of RNA recognition by RLRs.
  • Examines cellular pathways activated by RLR signaling.
