Inflammatory myopathies

Characterised intron retention profiles in muscle tissue of idiopathic inflammatory myopathy subtypes

Ann Rheum DisPublished Mechanistic study

Authors' conclusion

This study revealed distinct IRs and specific splicing factors associated with IIM subtypes, which might be contributing to the pathogenesis of IIM.
