ABSTRACT
The autoimmune liver disease primary biliary cirrhosis (PBC) is characterised by autoantibodies reactive with the pyruvate dehydrogenase complex (PDC). Observations from both human and murine settings suggest, however, that the key effecter immune response directed at the target biliary epithelial cells is T-cell, as opposed to antibody, mediated. Activated B-cells primed to bovine PDC are able to present mouse PDC-derived autoepitopes, thereby priming autoreactive T-cell responses. B-cells primed to foreign antigen but cross reactive with self drive the breakdown of T-cell tolerance to self-PDC seen in PBC.

    Primary biliary cirrhosis (PBC) is characterized by antimitochondrial antibodies (AMAs) that react with the lipoyl-containing E2 subunits of 2-oxoacid dehydrogenase complexes such as BCOADC and PDC. The lipoyl domains of E2 contain the major epitopes essential for immunopathology. However, the...
