abstract：:Antimicrosomal antibodies in inflammatory liver diseases all seem to be directed against members of the cytochrome P450 family of proteins. These autoantigens seem to be genetically polymorphic, the autoantibodies are inhibitory, and the autoepitopes are generally conserved among species. Anti-P450 autoantibodies shar...
