The deficiency of α1-antitrypsin (AAT) is secondary to misfolding and polymerization of the abnormal Z-AAT in liver cells and is associated with lung emphysema. Alveolar macrophages (AMs) produce AAT; however, it is not known whether Z-AAT can polymerize in AMs, further decreasing lung AAT and promoting lung inflammation. Our intention was to investigate whether AAT polymerizes in human AMs and to study the possible relation between polymerization and degree of lung inflammation.

Abstract
The deficiency of α1-antitrypsin (AAT) is secondary to misfolding and polymerization of the abnormal Z-AAT in liver cells and is associated with lung emphysema. Alveolar macrophages (AMs) produce AAT; however, it is not known whether Z-AAT can polymerize in AMs, further decreasing lung AAT and promoting lung inflammation. Our intention was to investigate whether AAT polymerizes in human AMs and to study the possible relation between polymerization and degree of lung inflammation.File in questo prodotto:
