Introduction: Organ-specific autoimmune diseases are believed to result from immune responses generated against self-antigens specific to each organ. However, when such responses target antigens expressed promiscuously in multiple tissues, then the immune-mediated damage may be wide spread.
Methods: In this report, we describe a mitochondrial protein, branched chain α-ketoacid dehydrogenase kinase (BCKDk) that can act as a target autoantigen in the development of autoimmune inflammatory reactions in both heart and liver.
Results: We demonstrate that BCKDk protein contains at least nine immunodominant epitopes, three of which, BCKDk 71–90, BCKDk 111–130 and BCKDk 141–160, …
