*3.1.4 Eosinophils*

A type of white blood cell containing granules that stain with eosin and is an effector cell in asthma as well as produces cytokines, e.g., IL-5 [15, 16]. In the airway of asthmatic patients, eosinophil-derived mediators of inflammation, including eosinophil-derived neurotoxin (EDN), major basic protein (MBP), and lysophospholipase (LPL), are toxic to the respiratory epithelium contributing to the immune pathogenesis of asthma in both children and adults [16].
