Recently, we replaced the lipoic acid moiety of PDC-E2 with a battery of synthetic structures designed to mimic a xenobiotically modified lipoyl hapten on a 12-aa peptide that was found within the immunodominant autoepitope of PDC-E2 and demonstrated that AMA in PBC reacted against several organic modified mimotopes as well as, or sometimes significantly better than, the native lipoyl domain. Based on this data, we immunized rabbits with one such xenobiotic organic compound, 6-bromohexanoate, coupled to BSA. One hundred percent of immunized rabbits developed AMA that have each and every characteristic of human AMAs with reactivity against PDC-E2, E2 subunit of branched chain 2-oxo-acid dehydrogenase, and E2 subunit of 2-oxoglutarate dehydrogenase complex. The rabbit AMA also inhibited enzymatic function of PDC-E2 and, importantly, binds to peptide sequences not present in the xenobiotic carrier immunogen. In contrast, BSA-immunized controls did not produce such activity. Our observation that animals immunized with a xenobiotic BSA complex produce autoantibodies that react not only with the xenobiotic, but also with mitochondrial autoantigens recognized by autoimmune PBC sera, suggests that environmental xenobiotic agents can be a risk factor for the induction of PBC.<\/jats:p>","DOI":"10.4049\/jimmunol.170.10.5326","type":"journal-article","created":{"date-parts":[[2014,4,20]],"date-time":"2014-04-20T19:31:23Z","timestamp":1398022283000},"page":"5326-5332","source":"Crossref","is-referenced-by-count":101,"title":["Immunization with a Xenobiotic 6-Bromohexanoate Bovine Serum Albumin Conjugate Induces Antimitochondrial Antibodies"],"prefix":"10.1093","volume":"170","author":[{"given":"Patrick S C","family":"Leung","sequence":"first","affiliation":[{"name":"Division of Rheumatology, Allergy and Clinical Immunology, School of Medicine, University of California , Davis, CA 95616"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chao","family":"Quan","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of California , Davis, CA 95616"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ogyi","family":"Park","sequence":"additional","affiliation":[{"name":"Division of Rheumatology, Allergy and Clinical Immunology, School of Medicine, University of California , Davis, CA 95616"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Judy","family":"Van de Water","sequence":"additional","affiliation":[{"name":"Division of Rheumatology, Allergy and Clinical Immunology, School of Medicine, University of California , Davis, CA 95616"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark J","family":"Kurth","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of California , Davis, CA 95616"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael H","family":"Nantz","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of California , Davis, CA 95616"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aftab A","family":"Ansari","sequence":"additional","affiliation":[{"name":"Department of Pathology, Emory University School of Medicine , Atlanta, GA 30322"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ross L","family":"Coppel","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Monash University , Clayton, Victoria ,","place":["Australia"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kit S","family":"Lam","sequence":"additional","affiliation":[{"name":"Division of Hematology\/Oncology, University of California, Sacramento Medical Center , Sacramento, CA 95817"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M Eric","family":"Gershwin","sequence":"additional","affiliation":[{"name":"Division of Rheumatology, Allergy and Clinical Immunology, School of Medicine, University of California , Davis, CA 95616"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2003,5,15]]},"reference":[{"key":"2026020210073730200_R1","volume-title":"Liver Biopsy Interpretation","year":"1980"},{"key":"2026020210073730200_R2","first-page":"210","volume-title":"Immunol.
