Abstract:
Asthma is a phenotypically heterogeneous chronic disease of the airways. Studies have found that neutrophils are crucial to airway inflammation in acute asthma, persistent asthma, particularly in asthma of poor response to glucocorticoid treatment. The role of neutrophils in development of bronchial asthma is complex, as they can release a potent source of cytokines and inflammatory mediators participating in asthma. Differing from eosinophilic inflammatory asthma, neutrophilic inflammatory asthma is not depend on helper T (Th)2 cells, but may be related to Th1 and Th17 cells. This review highlights the role of neutrophils in the development of asthma, and the treatment of neutrophilic asthma with biological agents and novel small molecules.

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.
Critical processes in asthma pathophysiology include:
Antiasthma Drugs: Leukotriene Modifiers
Leukotriene modifiers work through two distinct mechanisms:
Asthma-I: Introduction
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...
