An autoimmune marker, anti-mitochondrial antibody (AMA), is found in almost all patients with PBC; although other diseases may be associated with positive AMA, in PBC the antibody is directed against the pyruvate dehydrogenase complex (so-called M2 type of AMA), particularly to dihydrolipoamide acetyltransferase (E2) and E3-binding protein (107).
