Infection with malaria parasites can prevent progression to severe kidney disease in lupus-prone mice by preventing the migration of CCL17-producing dendritic cells to the kidneys.
An engineered protein that blocks CCR6–CCL20 signalling was able to prevent and treat skin, joint and entheseal inflammation in an IL-23-dependent mouse model of psoriatic arthritis.
In a new study, researchers have engineered exosomes that could be used to modulate the macrophage population in the synovium and promote resolution of arthritis.
Sensation of mechanical stimuli by chondrocytes is critical to cartilage homeostasis and osteoarthritis development. The earliest responses in chondrocyte mechanotransduction pathways involve calcium influx and changes in mitochondrial function, which occur in seconds to minutes. Deeper understanding of these events can elucidate new therapeutic targets for early intervention to prevent osteoarthritis.
Underrepresentation of patients with non-white skin in rheumatology educational resources impairs practitioners’ competence in caring for patients with skin of colour and reduces patients’ confidence in the medical system. Medical publishers and educators should reconsider how to promote equal representation and care of patients with all skin types.
Lyme arthritis, a manifestation of Lyme disease, can sometimes persist in a chronic post-infectious disease. In this Review, the authors argue that post-infectious Lyme arthritis could act as a model to improve understanding of other forms of chronic arthritis.
Genome editing technology, such as CRISPR–Cas, has great potential in the study of rheumatic disease genetics, including in discovering disease-associated genes and regulatory regions, in validating causal variants and in characterizing important cell types and cell states.
Advances in understanding the pathogenic mechanisms of primary Sjögren syndrome (pSS) and the development of new outcome measures are aiding drug development for this disease. This Review describes current treatments and highlights promising candidates for future therapies for pSS.
Tumour necrosis factor (TNF) inhibitors are effective treatments for autoimmune and rheumatic diseases. Here, Salomon reviews the complex pro-inflammatory and regulatory roles of TNF, highlighting its effects on the expansion, differentiation and suppressive function of regulatory T cells and their implications for the design of future anti-TNF agents.
