Abstract:
Evaluation of: Bree A, Schlerman FJ, Wadanoli M et al. IL-13 blockade reduces lung inflammation after Ascaris suum challenge in cynomolgus monkeys. J. Allergy Clin. Immunol. 119, 1251-1257 (2007). There is abundant evidence supporting IL-13 as having a central role in the pathology of allergic asthma. IL-13 induces immunological responses relevant to allergic asthma and exerts effects on airway structural cells, leading to remodeling and enhanced contractility of airway smooth muscle. This paper evaluates the results from a recent preclinical study in cynomolgus monkeys, showing that treatment with an antibody to IL-13 significantly attenuates airway inflammation induced by segmental allergen challenge. Efficacy of anti-IL-13 in proof-of-concept human studies will be critical to evaluate the potential of this therapy for treatment of 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...

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.
