The image shows knee articular cartilage from a chondrocyte-specific Bmal1-knockout mouse. The tissue was stained with safranin O and fast green. Deletion of the transcription factor brain and muscle Arnt-like protein 1 (BMAL1, also known as aryl hydrocarbon receptor nuclear translocator-like protein 1), a core component of the circadian clock, results in the loss of circadian rhythm and leads to degeneration of knee cartilage. The circadian clock controls the rhythmic expression of several hundred genes in cartilage and its function can be affected by inflammation and ageing, both of which are risk factors for osteoarthritis. Studies of the circadian clock will help us better understand cartilage physiology in health and disease.

  • Current guidelines for the treatment of osteoarthritis involve exercise and lifestyle modifications as well as pharmaceutical therapeutics for effective pain management. Is this message reaching patients, and are they exercising enough?

  • Seropositive RA can present with two different types of autoantibodies that have distinct features: anti-citrullinated protein antibodies (ACPAs) and rheumatoid factors (RFs). With a single-cell approach, researchers provide evidence that the underlying B cell subsets of these autoantibody specificities develop in parallel by different mechanisms.

  • A variety of comorbidities of gout exist, but most of these associations are not causally linked. Mendelian randomization analysis of genome-wide association study data now suggests that iron overload might increase serum uric acid levels and hence the risk of gout flares.

  • Environmental changes can sometimes be too rapid for genetic adaptation and result in a mismatch between our genetics and the environment. Osteoarthritis should be considered a mismatch disease owing to a rapid increase in prevalence that is associated with the modern lifestyle, diet and patterns of physical activity.
