Insights

MicroRNAs (miRNAs) regulate gene expression and immune responses in tuberculosis (TB). Understanding miRNA roles offers potential for diagnosing and treating this infectious disease.

Area of Science:

  • Immunology
  • Molecular Biology
  • Genetics

Background:

  • MicroRNAs (miRNAs) are key regulators of gene expression and cellular processes, particularly within the immune system.
  • Tuberculosis (TB) infection involves Mycobacterium tuberculosis evading host defenses by altering miRNA expression for survival and replication.
  • Dysregulated miRNAs are implicated in TB pathogenesis, influencing disease progression and host immune response.

Purpose of the Study:

  • To review the expression and multifaceted roles of miRNAs in tuberculosis (TB).
  • To explore miRNAs as immune modulators, diagnostic biomarkers, and therapeutic targets in TB.
  • To highlight miRNA involvement in host-directed therapies for TB.

Main Methods:

  • Literature review of scientific articles on miRNAs and tuberculosis.
  • Analysis of miRNA expression patterns in different TB infection phases.
  • Examination of miRNA functions in immune modulation, autophagy, and apoptosis.

Main Results:

  • Altered miRNA expression is crucial for Mycobacterium tuberculosis survival and infectivity within host cells.
  • miRNAs can differentiate between latent and active TB infection, serving as potential diagnostic biomarkers.
  • miRNA modulation of autophagy and apoptosis presents opportunities for host-directed therapeutic strategies.

Conclusions:

  • miRNAs are critical regulators of the immune response to TB and can serve as biomarkers.
  • Targeting miRNAs offers a promising avenue for novel diagnostic and therapeutic interventions against TB.
  • Further research into miRNA functions can advance host-directed therapies for TB.

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...

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...

Pulmonary Tuberculosis IV

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Pulmonary Tuberculosis II

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

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.

Pulmonary Tuberculosis III

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:
