Human Eosinophil degranulation in airway tissues is thought to make significant contributions to the pathogenesis of asthma, nasal polyposis, allergic rhinitis, and eosinophilic pneumonia.

It also alters pulmonary surfactant structure and function in asthma and the proteins are critical in the pathogenesis of tropical pulmonary eosinophilia (TPE).

Human Eosinophils are also associated with other diseases of the respiratory tract. Respiratory syncytial virus (RSV) is an important respiratory pathogens worldwide. Infection is often implicated in exacerbation of asthma in children.
