Z-AAT impairs organelle homeostasis and reduces adaptive response to lipids in alpha-1 antitrypsin deficiency models
Alpha-1 antitrypsin deficiency (AATD) caused by the Z variant leads to hepatic accumulation of misfolded AAT polymers and liver disease. Although proteotoxic stress is well established, its impact on lipid metabolism, mitochondrial function, and organelle homeostasis remains incompletely understood. The effects of Z-AAT accumulation were investigated in Z-HepG2 cells and 3D patient-derived ZZ…
