RT Journal Article T1 NAFLD and AATD Are Two Diseases with Unbalanced Lipid Metabolism: Similarities and Differences A1 Pérez Luz, Sara A1 Matamala, Nerea A1 Gómez-Mariano, Gema A1 Janciauskiene, Sabina A1 Martínez-Delgado, Beatriz AB Non-alcoholic fatty liver disease (NAFLD) is a type of steatosis commonly associated with obesity, dyslipidemia, hypertension, and diabetes. Other diseases such as inherited alpha-1 antitrypsin deficiency (AATD) have also been related to the development of liver steatosis. The primary reasons leading to hepatic lipid deposits can be genetic and epigenetic, and the outcomes range from benign steatosis to liver failure, as well as to extrahepatic diseases. Progressive hepatocellular damage and dysregulated systemic immune responses can affect extrahepatic organs, specifically the heart and lungs. In this review, we discuss the similarities and differences between the molecular pathways of NAFLD and AATD, and the putative value of hepatic organoids as novel models to investigate the physio pathological mechanisms of liver steatosis.
