Insights

MicroRNAs (miRNAs) regulate protein production and are crucial for immune responses. This review explores their role in immune-related diseases like chronic inflammatory skin conditions, autoimmunity, and viral infections.

Area of Science:

  • Molecular Biology
  • Immunology
  • Genetics

Background:

  • MicroRNAs (miRNAs) are small non-coding RNAs discovered in 1993 and defined in 2001.
  • They regulate gene expression post-transcriptionally by targeting messenger RNAs (mRNAs).
  • miRNAs are implicated in fundamental biological processes including development, differentiation, proliferation, and apoptosis.

Purpose of the Study:

  • To review the significant role of miRNAs in the pathogenesis of immune-related diseases.
  • To highlight the preferential targeting of immune genes by miRNAs.
  • To discuss the involvement of miRNAs in chronic inflammatory skin diseases, autoimmunity, and viral infections.

Main Methods:

  • Literature review of scientific publications on miRNAs and immune-related diseases.
  • Analysis of miRNA-mediated gene regulation mechanisms.
  • Synthesis of current knowledge on miRNA functions in immune system regulation.

Main Results:

  • miRNAs play a critical role in controlling protein production within cells.
  • Immune genes are disproportionately targeted by miRNAs compared to the broader human genome.
  • Dysregulation of miRNA function is linked to the development of various immune-related pathologies.

Conclusions:

  • miRNA-mediated regulation is vital for normal immune responses.
  • Understanding miRNA involvement is key to deciphering the pathogenesis of immune-related diseases.
  • miRNAs represent potential therapeutic targets for inflammatory, autoimmune, and infectious conditions.

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 the pre-miRNA...

Microorganisms in Medicine and Therapeutics

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.
Experimental RNAi02:15

Experimental 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...
Human Virome01:26

Human Virome

The human body harbors a vast and diverse viral community known as the human virome. The virome includes bacteriophages that infect bacteria, and eukaryotic viruses that infect human cells. Transient dietary and environmental viruses also contribute to this dynamic ecosystem. Estimates suggest the human body may contain on the order of 10¹³ viral particles, though abundance varies widely by body site and detection method.Comprehensive characterization of the virome has become possible only with...
