immune system
increased mature B cell number ( J:188560 )
• much greater frequency of IgA+ B cells in mesenteric lymph nodes and Peyer's patches compared to age matched controls
• significantly greater frequency and number of IgA+ B cells in the spleen in young mice immunized with a T cell dependent antigen
abnormal B cell physiology ( J:188560 )
• moderate increase in NKKB activation following induction
abnormal class switch recombination ( J:188560 )
• expression analysis indicates a defect in the negative regulation of class switching to IgA
increased IgA level ( J:188560 )
• production of antigen specific IgA in immunized mice is enhanced compared to similarly treated controls
• starting at 12 weeks of age serum IgA levels are increased in unimmunized mice compared to aged match controls
increased IgM level ( J:188560 )
• production of antigen specific IgM in immunized mice is moderately enhanced compared to similarly treated controls
increased anti-nuclear antigen antibody level ( J:188560 )
• higher serum titers of the autoantibody antinuclear antigen at 8 months of age

renal/urinary system
increased urine protein level ( J:188560 )
• at 8 months of age
abnormal kidney physiology ( J:188560 )
• prominent deposition of antibodies in the kidney glomeruli at 8 months of age a sign of nephropathy

homeostasis/metabolism
increased urine protein level ( J:188560 )
• at 8 months of age

hematopoietic system
increased mature B cell number ( J:188560 )
• much greater frequency of IgA+ B cells in mesenteric lymph nodes and Peyer's patches compared to age matched controls
