Zusammenfassung
HBV-specific CD8 T cells responses are considered to be targeted directly against HBV-infected hepatocytes leading to development of hepatitis. However, previous work by Schirmbeck et al revealed that CD8 T cells recognizing a peptide in the context of H2Kb, which is exclusively presented by cross-presenting cells, leads to elevated ALT levels. This supported the hypothessis that recognition of antigen on non-hepatocytes leads to CTL-mediated liver disease. To directly investigate the role of non-parenchymal liver cells in initiating of hepatitis, we employed transgenic mouse lines with cell-type specific expres…
