Die entzündliche Fettleber-Erkrankung (NASH) und der daraus resultierende Leberkrebs werden durch autoaggressive T-Zellen angetrieben. Wissenschaftlerinnen und Wissenschaftler aus dem Deutschen Krebsforschungszentrum (DKFZ) zeigen nun, was hinter diesem zerstörerischen Verhalten steckt. Sowohl bei Mäusen als auch bei Menschen mit NASH fanden sie eine gesteigerte Anzahl aktivierter B-Zellen im Magen-Darm-Trakt. Die B-Zellen fördern die Entstehung von Leberkrebs mit einer Doppelstrategie: Über direkten Zell-Zell-Kontakt aktivieren sie autoaggressive T-Zellen. Zusätzlich produzieren die B-Zellen Antikörper der Klasse IgA, die bestimmte Immunzellen aktivieren und dadurch die Leberfibrose antreiben. Werden die B-Zellen ausgeschaltet, so bilden sich bei Mäusen Entzündung und Fibrose zurück und es entstehen weniger und qztotxkq Gpmfxmdpidlz.
