Asthma and Allergies
In fact, the toughening and thickening of lung tissue seen in the lower airway in asthmatics has been connected with repeated bouts of allergies in the upper airways. The tissue changes are probably due to free radical scarring caused by the responder cells—neutrophils, T cells, and other leukocytes drawn to the inflamed site by histamines and other chemoattractants.26
In February 2004, researchers duplicated the characteristic smooth muscle thickening in asthmatic airways by repeatedly exposing rats to allergens and noting the changes in lung architecture. T cells, macrophages, eosinophils, lymphocytes, and neutrophils in lung fluid increased dramatically, resulting in the characteristic changes seen in the airway walls of asthmatics.26 New studies such as this reinforce the importance of controlling seasonal and year-round allergies; failure to control these conditions presents the very real danger of causing permanent structural changes to lung tissue.
