摘要 B cells play a pivotal role in the pathogenesis of autoimmune diseases.Although previous studies have shown many genetic polymorphisms associated with B-cell activation in patients with various autoimmune disorders,progress in epigenetic research has revealed new mechanisms leading to B-cell hyperactivation.Epigenetic mechanisms,including those involving histone modifications,DNA methylation,and noncoding RNAs,regulate B-cell responses,and their dysregulation can contribute to the pathogenesis of autoimmune diseases.Patients with autoimmune diseases show epigenetic alterations that lead to the initiation and perpetuation of autoimmune inflammation.Moreover,many clinical and animal model studies have shown the promising potential of epigenetic therapies for patients.In this review,we present an up-to-date overview of epigenetic mechanisms with a focus on their roles in regulating functional B-cell subsets.Furthermore,we discuss epigenetic dysregulation in B cells and highlight its contribution to the development of autoimmune diseases.Based on clinical and preclinical evidence,we discuss novel epigenetic biomarkers and therapies for patients with autoimmune disorders.
