When the body is exposed to allergens or irritants, it will trigger the immune systems through different mechanism. However, the common pathway would result to multi-cellular inflammation, enhanced bronchial responsiveness, airflow obstruction and activation of immunological cell infiltration. Here, the inflammatory cell infiltrate are composed of varying amounts of eosinophils, neutrophils, and lymphocytes.

Moreover, T cells in the lung appear to orchestrate an immune response with a strong T helper type 2 (Th2) component when allergens drive the process.
