Akkumulation von Eisen und α1-antitrypsin als hepatozelluläre Initiatoren der Leberfibrose

Wir wollen die Rolle von Eisenüberladung und α1-antitrypsin (AAT)-Mutation als human-relevante Leberfibrose-Initiatoren analysieren. Die Bedeutung der lysosomalen Dysfunktion wird in Hepcidin-Knockouts (KOs, Modell der Eisenüberladung) und AAT-mutierten Tieren untersucht, die mit p62 oder CHOP KOs verpaart wurden. Tierexperimente werden durch Evaluation der AAT Patienten vervollständigt, um die Mechanismen der Krankheitsentwicklung sowie die Rolle von modifizierenden Faktoren wie Übergewicht oder Alkoholkonsum zu adressieren.
