immune system
• B cells are resistant to Fas-mediated programmed cell death compared to controls
• increase in percentage of splenic plasma cells
• IgM and IgG deposits are seen in the kidneys
• CpG treatment enhances production of IgG dsDNA antibodies in serum as well as deposition of IgG in renal glomeruli, indicating development of autoimmune disease
