immune system
• 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
|
• moderate increase in NKKB activation following induction
|
• expression analysis indicates a defect in the negative regulation of class switching to IgA
|
• 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
|
• production of antigen specific IgM in immunized mice is moderately enhanced compared to similarly treated controls
|
• higher serum titers of the autoantibody antinuclear antigen at 8 months of age
|
• at 8 months of age
|
renal/urinary system
• at 8 months of age
|
• prominent deposition of antibodies in the kidney glomeruli at 8 months of age a sign of nephropathy
|
homeostasis/metabolism
• at 8 months of age
|
• at 8 months of age
|
• at 8 months of age
