KF4 Anti-Chymotrypsin-like Elastase 1 Antibody and Purified Alpha-1 Antitrypsin Have Similar but Not Additive Efficacy in Preventing Emphysema in Murine Alpha-1 Antitrypsin Deficiency.

Alpha-1 antitrypsin (AAT) deficiency is the most common genetic cause of emphysema. Chymotrypsin-like Elastase 1 (CELA1) is a serine protease neutralized by AAT and is important in emphysema progression. Cela1-deficiency is protective in a murine models of AAT-deficient emphysema.
