Zusammenfassung
The IL6/gp130 signalling in hepatocytes is protective in ConA hepatitis. To determine the cellular transducers in the IL6/gp130 dependend liver protection we generated mice with hepatocyte specific deletions for gp130 STAT or RAS signalling to differentiate the IL6/gp130 downstream cascades in this model. For the functional characterisation of these new transgenic mice, we isolated primary hepatocytes from ΔSTAT and ΔRAS mice, stimulated them with IL6 and analyzed the gp130 dependend STAT activation and the RAS/MAPK signalling. No STAT activation was observed in ΔSTAT primary hepatocytes after IL6, however ERK p…
