Identification of an Epitope from Adenine Nucleotide Translocator 1 That Induces Inflammation in Heart in A/J Mice.

ABSTRACT: Heart failure, a leading cause of death in humans, can emanate from myocarditis. Although most individuals with myocarditis recover spontaneously, some develop chronic dilated cardiomyopathy. Myocarditis may result from both infectious and noninfectious causes, including autoimmune responses to cardiac antigens. In support of this notion, intracellular cardiac antigens, like cardiac myosin heavy chain-α, cardiac troponin-I, and adenine nucleotide translocator 1 (ANT₁), have been identified as autoantigens in cardiac autoimmunity. Herein, we demonstrate that ANT₁ can induce autoimmune myocarditis in A/J mice by generating autoreactive T cells. We show that ANT₁ encompasses multiple immunodominant epitopes (namely, ANT₁ 21-40, ANT₁ 31-50
