Despite the transformative potential of treatments for systemic autoinflammatory diseases, these conditions remain underfunded and understudied. Urgent, coordinated action among stakeholders is needed to overcome regulatory and research barriers, as is innovation and advocacy for the development of effective therapies for these rare diseases.
The peptide hormone adropin, which is downregulated in dermal fibroblasts in patients with systemic sclerosis (SSc), inhibits TGFβ-mediated fibrosis in in vitro and ex vivo models of human skin, and has potential for the treatment of SSc.
EULAR’s 2023 updated recommendations for the non-pharmacological treatment of hip and knee osteoarthritis reiterates and confirms, in an abbreviated form, what we have known for more than a decade. Unfortunately, the abbreviated format of the updated recommendations lacks specificity and clinical usefulness. More detailed guidance could have facilitated wider uptake and improved care.
In this Review, the current landscape of tissue engineering for repair of articular cartilage is discussed, with reference to advances in cell sources, bioactive stimuli and the use of scaffolds, and with consideration of the challenges that result from the inflammatory articular environments in osteoarthritis and rheumatoid arthritis.
Relapsing polychondritis, a rare inflammatory disorder that affects cartilaginous structures, presents challenges in diagnosis owing to overlapping symptoms with other conditions. This Review provides a clinical update on relapsing polychondritis, emphasizing the importance of distinguishing this disease from similar conditions.
Granzyme serine proteases are known for their perforin-dependent cytotoxic activities, but evidence also indicates that they have a range of non-cytotoxic, pro-inflammatory intracellular and extracellular functions. In this Review, the authors discuss granzyme biology with an emphasis on its involvement in rheumatic disease pathology.
In this Review, Knight and Erkan consider how the 2023 ACR–EULAR classification criteria for antiphospholipid syndrome (APS) can guide future research to subphenotype APS by understanding its pathophysiology, paving the way for the personalized and proactive management of individuals with APS.
