immune system
• hyperresponsive to surface IgM crosslinking agents
• enhanced proliferative response to T cell receptor stimulation, even in younger mice
• kappa and lambda light chain levels elevated
• in older mice
• elevated IgG1 levels in older mice
• although normal in young mice, after 1 year of age, secondary lymph nodes become grossly enlarged
• expanded numbers of T and B lymphocytes
• disrupted architecture
• 3-6X increase of single positive T lymphocytes
• 2-3X increase of B220+ B lymphocytes
• rarely is enlarged in young mice
• increased autoantibodies to nuclear antigens
• heavy infiltration of lymphocytes into various organs in older mice
• clusters of lymphocytes in liver parenchyma
• immunoglobulin complex deposited in glomeruli
• perivascular and interalveolar infiltration of mononuclear cells

growth/size/body
• start to show signs of wasting at 15-16 months of age

hematopoietic system
• expanded numbers of T and B lymphocytes
• hyperresponsive to surface IgM crosslinking agents
• enhanced proliferative response to T cell receptor stimulation, even in younger mice
• kappa and lambda light chain levels elevated
• in older mice
• elevated IgG1 levels in older mice

liver/biliary system
• clusters of lymphocytes in liver parenchyma

respiratory system
• perivascular and interalveolar infiltration of mononuclear cells

renal/urinary system
• immunoglobulin complex deposited in glomeruli
