Lung Macrophages and Asthma. Mainly, three classes of macrophages are identified in the lung tissue: bronchial macrophages (BMs), alveolar macrophages (AMs), and interstitial macrophages (IMs). BMs are isolated from induced sputum, while AMs are found in alveoli lumen, presiding a nonspecific innate defense mechanism.lveolar macrophages (AMs), one of the prominent immune system cells found in the airways, have been implicated in the development and progression of asthma. AMs constitute a unique subset of pulmonary macrophages, which serve as a first line of defense against foreign invaders to the lung tissue.
