Rheumatoid arthritis (RA) is an autoimmune condition that leads to joint inflammation. Lee et al. (see the Perspective by Firestein) identify a new regulator of the cellular organization of the synovium that might also provide a potential therapeutic target for inflammatory arthritis. Mice lacking the cell adhesion molecule cadherin-11 showed significantly reduced growth of the synovium and were resistant to the development of an experimentally induced RA-like condition. Joint inflammation in mice could be inhibited with a monoclonal antibody to cadherin-11.
