The formation of ordered Z α 1 ‐antitrypsin polymers is central to liver disease in α 1 ‐antitrypsin deficiency. The nascent α 1 ‐antitrypsin folds via the M* intermediate to native monomer or becomes incorporated into a soluble polymer that can be secreted, degraded or precipitate as insoluble inclusions. We describe the kinetics of the clearance of Z α 1 ‐antitrypsin polymers and show that they can be abolished with a small molecule preventing the formation of M*.
