Autoantibodies to double-stranded DNA (dsDNA), produced by auto-reactive plasma cells (PC), are a hallmark of systemic lupus erythematosus (SLE) and play a key role in disease pathogenesis. Recent data suggests that auto-reactive PC accumulate not only in lymphoid tissues but also in the inflamed kidney in lupus nephritis. We hypothesized that the variable efficacy of anti-CD20 (rituximab) mediated B cell depletion (BCD) in SLE may be related to the absence of an effect on auto-reactive PCs in the kidney. Here we report that an enrichment of auto-reactive dsDNA antibody secreting cells (ASC) in the kidney of lupus-prone mice (up to 40% of the ASCs) coincided with a progressive increase in splenic germinal centers (GC) and PCs and an increase in renal expression for PC survival factors (BAFF, APRIL and IL6) and PC attracting chemokines (CXCL12). Short-term treatment with anti-CD20 (4 weeks), neither decreased anti-dsDNA nor IgG ASCs in different anatomical locations. However, long-term treatment (12 weeks) significantly reduced both IgG- and dsDNA specific ASCs. In addition, long-term treatment substantially decreased splenic GC- and PC generation and unexpectedly reduced the expression for PC survival factors in the kidney. These results suggest that prolonged BCD may alter the PC survival niche in the kidney, regulating the accumulation and maintenance of auto-reactive PCs.
