| Popis: | In recent years, various myositis-specific and myositis-associated autoantibodies have been identified in idiopathic inflammatory myopathies, including dermatomyositis (DM), anti-synthetase syndrome (ASS), immune-mediated necrotizing myopathy (IMNM), and inclusion body myositis (IBM). These autoantibodies exhibit unique characteristics in terms of organ involvement, severity, and treatment response, making their understanding crucial for accurate diagnosis and effective therapy. This review provides a comprehensive overview of the clinical features of recently discovered myositis-specific and associated autoantibodies, while exploring their potential roles in the pathogenesis and exacerbation of myositis. Key findings include the production of anti-TIF1γ antibodies in model mice, the upregulation of Mi2-related genes in anti-Mi2 antibody-positive dermatomyositis muscle tissue, and Jo-1 antigen-induced T cell activation, shedding light on whether disease mechanisms are driven by autoantibodies or autoantigens. |
