|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. Chronic inflammation can possibly cause irreversible changes to the airways in the lungs.
Journal Article is sometimes called a Scientific Article, a Peer-Reviewed Article, or a Scholarly Research Article. Together, journal articles in a particular field are often referred to as The Literature.
Journal articles are most often Primary Research Articles. However, they can also be Review Articles. These types of articles have different aims and requirements. Sometimes, an article describes a new tool or method.
