Understanding the Immunopathogenesis of Autoimmune Disorders: A Comprehensive Review

Autoimmune disorders comprise a broad category of illnesses marked by abnormal immune reactions against self‑antigens, resulting in persistent inflammation and tissue damage. This comprehensive review examines the complex mechanisms underlying the development of autoimmune disease, focusing on immunopathogenesis. We discuss the interplay between genetic predispositions, environmental triggers, and pathogens in the initiation and perpetuation of autoimmunity. Key cytokines and inflammatory pathways are highlighted to illustrate their roles in disease progression. We then explore the distinct pathogenic mechanisms of organ‑speciϐic autoimmune disorders, including autoimmune thyroid diseases, autoimmune hemolytic anemia, neuromyelitis optica, idiopathic inflammatory myopathies, and inflammatory bowel disease, while also reviewing the influence of gut microbiome dysbiosis on immune function. Lastly, we address biomarker identiϐication for early detection, current therapeutic strategies, and emerging treatments that target novel pathways. By integrating ϐindings from diverse studies, this review provides a holistic understanding of the immunological landscape of autoimmune disorders, paving the way for improved diagnostic and therapeutic options
