Host defense function of the airway epithelium in health. Otitis media (OM) is a highly prevalent pediatric disease caused by normal flora of the nasopharynx that ascend the Eustachian tube and enter the middle ear. As OM is a disease of opportunity, it is critical to gain an increased understanding of immune system components that are operational in the upper airway and aid in prevention of this disease., Host defense in oral and airway epithelia: chromosome 20 contributes a new protein family. These include the natural defences of saliva and airway surface lining fluid (ASL), the host innate immune responses, as well as the ability to generate antibodies via acquired immune responses..

Sep 12, 2003В В· Respiratory infection is extremely common and a major cause of morbidity and mortality worldwide. The airway epithelium has an important role in host defense against infection and this is illustrated in this review by considering infection by respiratory viruses. Background: Airway epithelial cells are critical in host defense against bacteria including Mycoplasma pneumoniae (Mp) in chronic obstructive pulmonary disease (COPD) and asthma. ОІ2-agonists are mainstay of COPD and asthma therapy, but whether ОІ2-agonists directly affect airway epithelial host defense functions is unclear.
