Arthritis affects millions of people, but the underlying causes are still not fully understood. What makes the immune system that normally protects us suddenly attack our joints? And why do arthritis flares seem to arrive without warning?

In this episode, we explore how certain immune cells or signals might be responsible for switching inflammation on.

We hear from Garvan's Dr Etienne Masle-Farquhar, who is mapping these processes in both rheumatoid arthritis and osteoarthritis, with the goal of predicting flares earlier and guiding more effective treatment.
