MSC2360844 treatment in the IFNα-accelerated SLE model led to a decrease in numbers of ASCs (Figure 6F), CD138+ plasma cells, IgG+ class-switched B cells (Table 2) in the spleen as well as a decrease in IgG2 depositions in the kidney (Figure 6D). This evidence concerns the gene SDC1 and systemic lupus erythematosus.
