Consequently therapeutic targeting of B cells is gaining prominence in our clinical armamentarium for an ever expanding array of autoimmune and neoplastic disorders. Therefore it is of great importance to understand the mechanism of action of B cell depletion. Given that the ideal consequence of B cell depletion would be the subsequent re-establishment of immunologic tolerance a detailed analysis of the properties of the emerging repertoire will be required. The results presented by Rouziere and coworkers in their study of rheumatoid arthritis patients shed some light on this question and are discussed in this commentary. As reflected in the work by Rouziere and coworkers 1 B cells have become a major therapeutic target for autoimmune diseases. This prominence stems from two convergent developments. One of these is the understanding that in addition to conventional antibody dependent effects B cells also play important regulatory and potentially pathogenic roles through antibody independent mechanisms including antigen presentation T cell activation and polarization dendritic cell regulation and cytokine and chemokine production 2 . Moreover mounting clinical evidence strongly supports the therapeutic benefit of targeting B cells in an array of .
