While autoimmune disorders are characterized by lymphocyte-driven antigen-specific responses, autoinflammatory diseases are driven by chronic activation of the innate immune system. However, to date, both groups of disorders lack clear understanding for their onset and the functional mechanisms conducive to their pathology and have few efficacious, safe, and/or curative treatment options for patients. The SH2 domain–containing protein tyrosine phosphatase (SHP2), the protein encoded by the <em>PTPN11</em> gene, is a nodal enzyme involved in embryogenesis, development, proliferation, differentiation, and survival of cells. Mutations in <em>PTPN11</em> are associated with the development of congenital disorders as well as several types of cancers. Recently, links between autoimmunity and genetic developmental disorders have also revealed a key role for SHP2 activity in autoimmune–autoinflammatory pathophysiology. Its association with these disorders has begun to unravel the molecular mechanisms that contribute to the onset of autoimmunity. In this review, we will discuss the emergent role of SHP2 in autoimmunity and the current known and unknown molecular mechanisms of its regulation in these processes and propose the translational impact it may have as a therapeutic in the near future.</div></div>","PeriodicalId":52156,"journal":{"name":"Current Opinion in Physiology","volume":"45 ","pages":"Article 100833"},"PeriodicalIF":2.5,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144230197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The first known mito-ncRNAs that exit mitochondria were those generated from the control regions of the mitochondrial genome. Recent evidence suggests that this phenomenon is broader, encompassing multiple mitochondrial sense and antisense transcripts and mito-tRNAs. mito-ncRNAs are regulated by the proliferative state of the cell, physiological stresses, and viral infections. Both within and outside the organelle, mito-ncRNAs serve as scaffolds for protein complex assembly, as modulators of promoter occupancy, heterochromatin states, nucleolar functions, and spliceosome selectivity, and as precursors and regulators of miRNA networks.
