Antibody-secreting cells are important for the pathophysiology of SLE and RA, but researchers have been unable to determine how these cells are activated. A new technique is able to distinguish between naïve autoreactive B cells and established antibody secreting cells…
In recent years, scientists and clinicians have learned a great deal about autoantibodies occurring in idiopathic inflammatory myopathies (IIMs). These new discoveries have reshaped our understanding of distinct clinical phenotypes in IIMs. Scientists continue to learn more about how these autoantibodies shape pathophysiology, diagnosis, disease monitoring, prognosis and optimum treatment. Moving forward, these autoantibodies will…
A study in mice provides insight into the maturation of the self-reactive B cell response, contextualizing the epitope spreading observed in autoimmune disease. Researchers found that clonal expansion of wild type B cells in autoreactive germinal centers appeared to be at the heart of epitope spreading and the consequent autoimmune response…
Research in The New England Journal of Medicine has opened new avenues for exploring the pathophysiology of disease flares in rheumatoid arthritis.1 Through longitudinal genomic analysis, researchers have identified a naive B cell signature prior to rheumatoid arthritis flares, as well as a type of mesenchymal cell, that may play an important role in flare…
