Airway inflammation is a state of disturbance in the airways where the immune system responds to an apparent threat and causes swelling, itching, redness, and different side effects. Airway inflammation can occur in response to exposure to particulates like dust, toxins, allergens, and different substances. Features of the disease are reversible airflow obstruction, extensive leukocyte infiltration, mucus overproduction, airway hyperresponsiveness and inflammation leading to tissue damage and remodeling. Exhaled nitric oxide is an effective biomarker for airways inflammation. Airways are highly affected in asthma, COPD, allergic rhinitis and other respiratory diseases. The airways are narrowed which is associated with airway hyperresponsiveness and variable airflow obstruction. Multiple cell types such as T helper 2 cells, regulatory T cells, eosinophils, dendritic cells, mast cells, and parenchymal cells of the lung are involved in the pathogenesis.
Scholarly journal is a peer-reviewed journal in which scholarship relating to a particular academic discipline is published.
