Targeting eosinophils in severe asthma shows promise for reducing airway remodeling and disease progression. Understanding eosinophilic asthma phenotypes, endotypes, and biomarkers is key to developing effective targeted therapies.
Area of Science:
- Immunology
- Pulmonology
- Pharmacology
Background:
- Asthma affects 300 million globally, characterized by airway inflammation and remodeling.
- Eosinophilic asthma involves eosinophil accumulation, releasing mediators that worsen inflammation and damage.
- Targeting eosinophils may mitigate airway remodeling and slow asthma progression.
Purpose of the Study:
- To review the role of eosinophils in severe asthma.
- To explore eosinophilic asthma phenotypes, endotypes, and biomarkers.
- To examine current and emerging biologic agents targeting eosinophils.
Main Methods:
- Literature review of immunopathology, biomarkers, and targeted therapies for eosinophilic asthma.
- Analysis of phenotypes and endotypes contributing to severe asthma.
- Evaluation of biological agents targeting eosinophil-driven inflammation.
Main Results:
- Eosinophils significantly contribute to severe asthma inflammation and tissue damage.
- Accurate patient categorization by phenotype and endotype is crucial.
- Various biomarkers are associated with eosinophilic asthma pathology.
Conclusions:
- Understanding eosinophil immunopathology is vital for severe asthma management.
- Targeted therapies focusing on eosinophils offer potential for improved treatment outcomes.
- Further research into eosinophil-specific biomarkers and therapies is warranted.

Asthma: Pathogenesis and Management
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.
Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
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...
