Background: Idiopathic inflammatory myopathies (IIM) are a heterogeneous group of autoimmune disorders with uncertain pathogenesis. Interferon (IFN)-λ has recently been described as an important mediator of immune responses. The main purpose of this study is to find out whether IFN-λ is involved in IIM.

Dermatomyositis (DM) is a rare autoimmune disease defined by the presence of characteristic cutaneous findings, an increased cancer risk, and variable extracutaneous pathology involving the muscles, lungs, gastrointestinal tract, heart, and/or joints. Although the pathogenesis of DM remains incompletely understood, the discovery of myositis-specific autoantibodies has been an important step forward in understanding disease heterogeneity in DM and stratifying risk for extracutaneous disease and malignancy. Moreover, the recent elucidation of key immunologic drivers of DM has laid the groundwork for the development of novel, targeted treatments in the DM therapeutic pipeline.

Autoantibodies are important for the diagnosis of autoimmune interstitial lung disease (ILD). Standard immunoassays have limitations, including their qualitative nature and/or a narrow dynamic range of detection, hindering the usefulness of autoantibodies as biomarkers of disease activity. Here, the luciferase immunoprecipitation system (LIPS) was evaluated for measuring myositis-specific and other lung-related autoantibodies in 25 subjects with idiopathic inflammatory myopathies (IIM), 26 with Sjögren's disease (SjD), and 10 healthy volunteers.

Dermatomyositis (DM) is a rare autoimmune systemic disorder manifesting with typical skin rashes and proximal muscle weakness. A specific clinical DM subset is characterized by the presence of the anti-melanoma differentiation-associated protein 5 (MDA5) autoantibodies. These patients are usually burdened by a severe clinical phenotype exhibiting a poor prognosis.

Regression (total or partial) is a common phenomenon in melanoma. From a pathogenic perspective, it is highly complex and only partially understood, involving aspects of both the tumor and the individual. One of the determining factors is the clonal selection of the tumor, wherein some clones within the tumor survive while others perish.
