Insights

MicroRNAs regulate gene expression and are crucial for immune cell function. This review explores microRNA (miRNA) roles, particularly miR-155, in immunity and their therapeutic potential for immune diseases.

Area of Science:

  • Molecular Biology
  • Immunology
  • Genetics

Background:

  • MicroRNAs (miRNAs) are key regulators of gene expression, influencing numerous cellular processes.
  • Dysregulation of miRNAs significantly impacts immune cell development and function, as shown in Dicer knockout models.

Purpose of the Study:

  • To review the role of miRNAs, with a focus on miR-155, in innate and adaptive immunity.
  • To discuss the potential of miRNAs as diagnostic and therapeutic targets for immune system disorders.

Main Methods:

  • Literature review of studies on miRNA function in immunity.
  • Analysis of predicted and known mRNA targets of miRNAs, especially miR-155.
  • Examination of the impact of miRNAs on immune cell development and function.

Main Results:

  • MiRNAs, including miR-155, play critical roles in regulating lymphocytes and immune responses.
  • Specific miRNAs target multiple mRNAs, enabling precise control over cellular processes within the immune system.
  • Aberrant immune cell development and function are observed in conditions with disrupted miRNA regulation.

Conclusions:

  • MiRNAs are essential regulators of both innate and adaptive immunity.
  • miR-155 is a significant miRNA involved in lymphocyte function and immune regulation.
  • MiRNAs hold promise as novel biomarkers and therapeutic targets for immune diseases.

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After...

siRNA - 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...

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...

Immune Response Against Viral Pathogens01:29

Immune Response Against Viral Pathogens

The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
