Global Molecular Effects of Tocilizumab Therapy in Rheumatoid Arthritis Synovium

The molecular similarities between the effects of TCZ, RTX, and MTX therapies in the RA synovium indicate that B cell- and IL-6-dependent pathways play synergistic roles in the pathogenesis of the disease, in particular through activation of T cell responses. Moreover, these results open perspectives for the individualization of therapeutic decisions, based on a better knowledge of the synovial molecular effects of each type of RA therapy.
