Insights

MicroRNAs (miRNAs) are key regulators of gene expression. This review explores their emerging roles in allergic diseases, including their function in inflammation and potential as biomarkers.

Area of Science:

  • Molecular Biology
  • Immunology
  • Genetics

Background:

  • MicroRNAs (miRNAs) are small RNA molecules regulating gene expression by targeting messenger RNAs (mRNAs).
  • miRNAs influence a vast number of genes, impacting cellular functions and disease development.
  • Their role in human diseases is increasingly recognized, with recent focus on allergic conditions.

Purpose of the Study:

  • To review the functions of miRNAs in the development of allergic diseases.
  • To highlight the role of miRNAs in regulating T-helper 2 (Th2) cell polarization and inflammation.
  • To discuss extracellular miRNAs as potential noninvasive biomarkers and advances in miRNA-based therapeutics.

Main Methods:

  • Literature review of studies on miRNA function in allergic diseases.
  • Analysis of miRNA regulatory mechanisms in Th2 polarization and inflammatory responses.
  • Examination of research on extracellular miRNAs and therapeutic strategies.

Main Results:

  • miRNAs play significant roles in modulating Th2 immune responses central to allergies.
  • Dysregulated miRNA expression is implicated in the pathogenesis of various allergic conditions.
  • Extracellular miRNAs show promise as noninvasive biomarkers for allergic disease diagnosis and prognosis.

Conclusions:

  • miRNAs are critical regulators in allergic disease development.
  • Extracellular miRNAs offer a novel avenue for noninvasive diagnostics in allergy.
  • Targeting miRNAs presents a promising therapeutic strategy for allergic diseases.

Asthma I: Introduction

Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...

Microbiota of the Respiratory Tract

The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more...

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

Asthma-I: Introduction01:29

Asthma-I: Introduction

Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Asthma-II: Pathophysiology and Classification

Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
