Asthma-II: Pathophysiology and Classification

2.7K
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:

Asthma: Pathogenesis and Management

394
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Asthma-I: Introduction

2.6K
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...

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

288
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...

Human Genetics01:28

Human Genetics

566
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

Area of Science:

  • Pulmonary Medicine
  • Genetics
  • Biomarker Discovery

Background:

  • Asthma prevalence surged in the late 20th century, affecting ~260 million people globally in 2019.
  • While biologics target T2-high asthma, the mechanisms of various asthma endotypes remain unclear.
  • Current biomarker discovery relies on transcriptomics and proteomics, often biased towards T2-high phenotypes.

Purpose of the Study:

  • To review the potential of epigenomic analysis for understanding broader asthma endotypes.
  • To explore how epigenomic data can identify novel therapeutic targets for diverse asthma subtypes.

Main Methods:

  • Literature review focusing on epigenomic studies in asthma.
  • Analysis of existing transcriptomic and proteomic data limitations.
  • Synthesis of current knowledge on asthma endotypes and biomarkers.

Main Results:

  • Epigenomic data may offer a more comprehensive view of asthma endotypes compared to current methods.
  • This approach could reveal alternative pathways for therapeutic intervention.
  • Potential for identifying biomarkers for previously understudied asthma phenotypes.

Conclusions:

  • Epigenome-wide analysis presents a promising avenue for a deeper understanding of asthma heterogeneity.
  • This approach may lead to the development of novel, targeted therapies for a wider range of asthma patients.
  • Further research into epigenomic datasets is warranted to fully elucidate asthma mechanisms.
