Advances in our understanding of immune cell receptors and the development of biologic agents targeting them have revolutionized the treatment of rheumatoid arthritis (RA). Now, inhibitors of kinases integral to the signalling pathways downstream of these receptors have been added to the therapeutic armamentarium. This Review discusses the signalling pathways and small-molecule inhibitors of their component kinases that have already shown, or are predicted to show, promise in the treatment of RA.
