Ph.D candidate (f/m/d) (65 %)

initially for a duration of 36 months

Project description :

Metabolic dysfunction-associated steatotic liver disease (MASLD) is characterized by accumulation of lipid droplets in the liver and represents a major cause of chronic liver disease. MASLD harbors the risk of progression to steatohepatitis and even to a life-threatening end stage disease, such as hepatocellular carcinoma (HCC). A critical step driving the progression of a “benign” MAFLD to steatohepatitis is the infiltration of monocytes/macrophages in the liver and the subsequent formation of macrophage crowns surrounding lipid droplets (lipogranulomas). The project aims at understanding the mechanisms underlying lipogranuloma formation and resolution and their relevance for disease progression. The project is part of the research unit FOR5889 “dangerhep” recently funded by the Deutsche Forschungsgemeinschaft (DFG), including also outstanding principal investigators from the Universities of Düsseldorf, Stuttgart and Tübingen.
