While trace metals such as selenium (Se), zinc (Zn), and copper (Cu) are essential for the regulation of immune and inflammatory responses, excessive or imbalanced exposure can disrupt physiological homeostasis. In contrast, exposure to heavy metals including lead (Pb), mercury (Hg), cadmium (Cd), and nickel (Ni) poses significant risks to joint health and has been increasingly associated with progressive joint tissue deterioration. Accumulating evidence indicates that metal-induced toxicity disrupts cellular homeostasis by promoting reactive oxygen species (ROS)-mediated oxidative stress and impairing key cellular processes, including apoptosis, ferroptosis, mitochondrial dysfunction, and endoplasmic reticulum (ER) stress. Moreover, heavy metals may interfere with the autophagy–lysosomal pathway, a critical mechanism for maintaining cellular integrity and immune balance. This review underscores the importance of understanding the complex interactions between heavy and trace metal exposure and their roles in cellular dysfunction and joint tissue degeneration. Elucidating the molecular mechanisms underlying metal-induced toxicity is essential for the development of targeted therapeutic strategies and effective preventive interventions aimed at mitigating RA progression.</div></div>","PeriodicalId":8664,"journal":{"name":"Autoimmunity reviews","volume":"25 3","pages":"Article 104003"},"PeriodicalIF":8.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146137055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditionally, given the intracellular nature of their targets, myositis autoantibodies were thought to be non-pathogenic. However, this idea is now being challenged based on data from recent and older studies showing that autoantibodies reach their intracellular targets <em>in vivo</em> and exert functional pathogenic effects. In this review, we summarize experimental evidence supporting a model of pathogenic autoantibody internalization in the skeletal muscle of different inflammatory myopathies.

We discuss possible mechanisms of autoantibody entry, as well as the diagnostic, prognostic, and therapeutic implications of this model.
