Targeting B cells for current and potential therapeutic approaches in RA. (A) Therapeutic approaches already approved in human. (B) Therapeutic approaches under evaluation in human. (C) Potential therapeutic approaches (only tested in mouse model of CIA or in experiments in vitro). Figure 5 summarizes the drugs or cells that target B cells to treat RA. These drugs or cells are either approved in the clinical trial phase of RA, or we believe that they may be used for RA treatment. Jaks, Janus kinases; IL-21R, IL-21 receptor; IL-6R, IL-6 receptor; BAFFR, B cell activating factor receptor; BCMA, B cell maturation antigen; TACI, transmembrane activator and calcium modulator; BTK, Bruton’s tyrosine kinase; anti-FITC CAR-T cell, antifluorescein isothiocyanate chimeric antigen receptor T cells.
