Such immunized rabbits develop high-titer Abs to pyruvate dehydrogenase complex (PDC)-E2, the major autoantigen of primary biliary cirrhosis. In efforts to map the fine specificity of these autoantibodies, rabbits were immunized biweekly with 6-bromohexanoate-BSA and screened for reactivity using a unique xenobiotic-peptide-agarose microarray platform with an emphasis on identifying potential structures that mimic the molecular image formed by the association of lipoic acid with the immunodominant PDC-E2 peptide. Essentially, a total of 23 xenobiotics and lipoic acid were coupled to the 12-mer peptide backbones, PDC, a mutant PDC, and albumin. As expected, we succeeded in breaking tolerance using this small organic molecule coupled to BSA. However, unlike multiple experimental methods of breaking tolerance, we report in this study that, following continued immunization, the rabbits recover tolerance. With repeated immunization, the response to the rPDC-E2 protein increased with a gradual reduction in autoantibodies against the lipoic acid-peptide, i.e., the primary tolerance-breaking autoantigen. Detailed analysis of this system may provide strategies on how to restore tolerance in patients with autoimmune disease.<\/jats:p>","DOI":"10.4049\/jimmunol.172.10.6444","type":"journal-article","created":{"date-parts":[[2014,4,20]],"date-time":"2014-04-20T20:55:35Z","timestamp":1398027335000},"page":"6444-6452","source":"Crossref","is-referenced-by-count":51,"title":["Xenobiotic-Induced Loss of Tolerance in Rabbits to the Mitochondrial Autoantigen of Primary Biliary Cirrhosis Is Reversible"],"prefix":"10.1093","volume":"172","author":[{"given":"Katsushi","family":"Amano","sequence":"first","affiliation":[{"name":"Division of Rheumatology, Allergy, and Clinical Immunology, University of California , Davis, CA 95616"},{"name":"Division of Gastroenterology and Hepatology, Department of Internal Medicine, Jikei University School of Medicine , Tokyo ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrick S C","family":"Leung","sequence":"additional","affiliation":[{"name":"Division of Rheumatology, Allergy, and Clinical Immunology, University of California , Davis, CA 95616"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qingchai","family":"Xu","sequence":"additional","affiliation":[{"name":"University of California Davis Cancer Center, Division of Hematology and Oncology, Department of Internal Medicine, University of California at Davis , Sacramento, CA 95817"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan","family":"Marik","sequence":"additional","affiliation":[{"name":"University of California Davis Cancer Center, Division of Hematology and Oncology, Department of Internal Medicine, University of California at Davis , Sacramento, CA 95817"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chao","family":"Quan","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of California , Davis, CA 95616"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark J","family":"Kurth","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of California , Davis, CA 95616"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael H","family":"Nantz","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of California , Davis, CA 95616"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aftab A","family":"Ansari","sequence":"additional","affiliation":[{"name":"Department of Pathology, Emory University , Atlanta, GA 30322"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kit S","family":"Lam","sequence":"additional","affiliation":[{"name":"University of California Davis Cancer Center, Division of Hematology and Oncology, Department of Internal Medicine, University of California at Davis , Sacramento, CA 95817"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mikio","family":"Zeniya","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology and Hepatology, Department of Internal Medicine, Jikei University School of Medicine , Tokyo ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ross L","family":"Coppel","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Monash University , Clayton, Victoria ,","place":["Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M Eric","family":"Gershwin","sequence":"additional","affiliation":[{"name":"Division of Rheumatology, Allergy, and Clinical Immunology, University of California , Davis, CA 95616"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2004,5,15]]},"reference":[{"key":"2026020211272838400_R1","first-page":"129","volume-title":"Immunol.
