A study published in Nature Biomedical Engineering reports a new biomimetic lubricant that can help restore cartilage in rats with post-traumatic osteoarthritis.
The results of several retrospective studies have reported that systemic treatment in patients with psoriasis reduces the risk of incident psoriatic arthritis (PsA). Although encouraging from a prevention perspective, such studies are limited in their ability to provide a conclusive understanding of PsA risk, preventing a clear picture from emerging.
In this Review, the authors provide an introduction to machine learning and discuss the use of this approach in rheumatic autoimmune inflammatory diseases, including the classification of patients based on medical records or molecular characteristics, identification of novel biomarkers or drug repurposing candidates and prediction of disease progression or onset.
In this timely Review, the authors compare and contrast two forms of childhood inflammatory vasculitis: Kawasaki disease and the coronavirus disease 2019 (COVID-19)-associated multisystem inflammatory syndrome in children, highlighting epidemiological, clinical and immunological differences that suggest they should be classified as distinct syndromes.
Regulatory T (Treg) cells have crucial roles in peripheral tolerance and limiting inflammation, and IL-2 is an important cytokine for Treg cell differentiation, activity and homeostasis. In this Review, Kolios, Tsokos and Klatzmann provide an overview of Treg cell and IL-2 involvement in rheumatic diseases and how modulating IL-2 signalling and Treg cell biology might provide novel treatment avenues.
