JAKi significantly increased osteoblast function but showed no direct effects on osteoclasts. JAK signalling has emerged as an important therapeutic target for inflammatory disease, and the immunomodulation of JAK inhibition is well defined. Less well understood is the influence of this new class of drugs on bone homeostasis. This is important, as cytokine dysregulation triggers bone loss, and periarticular erosions contribute to the pathogenesis of RA. This study investigated the effect of B...

Single cytokine inhibition, e.g. TNFα or IL-6, has fundamentally improved the therapeutic armamentarium for the treatment of RA; yet clinically meaningful responses are achieved in only about half of RA patients treated. In addition, it is now well established that the pathogenesis of RA involves multiple mechanisms of cell activation and cell recruitment. These two factors have led to the emergence of the concept of dual specificity, sparking interest in the biologic arena, with a foc...
