immune system
• mice have severe splenomegaly by 10 months of age with cellularity at least 3-fold greater than in controls
• increases size is from an increased number of memory CD4+ T cells and B cells
• increased mature B cell numbers are found in the spleen of 10 month old mice
• increased memory/effector (CD4+ CD44+) T cells are found in the spleen of 10 month old mice
• sera levels of IgG1 are 10-fold higher in mice 10 months of age
• sera levels of IgM are 10-fold higher in mice 10 months of age
• a large amount of anti-dsDNA IgM and IgG1 is found in the sera of 10 month old mice
• a large amount of anti-histone IgM and IgG1 is found in the sera of 10 month old mice
