Abstract:
Bronchial asthma is a heterogeneous chronic inflammatory disease involving multiple immune cells and structural cells.It is characterized by airflow limitation,airway hyperresponsiveness,and airway remodeling,with complex pathogenesis.In recent years,the research on exosomes has developed rapidly.Exosomes are small vesicles secreted by a variety of cells and are naturally found in various biological fluids,with stability and biocompatibility.Exosomes from different cells are involved in pathophysiological processes such as airway inflammation,remodeling,and hyperresponsiveness through specific mechanisms and play a regulatory role in multiple links in bronchial asthma.This review focuses on the role of exosomes from different cells in the pathogenesis of bronchial asthma.

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.
Asthma-II: Pathophysiology and Classification
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.

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...
