immune system
• dendritic cell number increases with age in the spleen
• mice exhibit histological changes in the spleen
• loss of follicular architecture is associated with splenomegaly
• splenomegaly is associated with loss of follicular architecture
• dendritic cells are spread throughout the periarteriolar lymphoid sheath
• mice have hyperimmunoglobulinemia
• elevation in anti-nuclear antibodies occurs as early as 8 weeks in some mice and by 12 to 16 weeks in most mice

liver/biliary system
• mice exhibit histological changes in the liver
• polymorphic infiltrate, including Itgax+ dendritic cells and various
• leukocytes, is found around central veins in the liver

cellular
• bone marrow dendritic cells are resistant to apoptosis following stimulation with LPS and exposure to CT26 carcinoma cells transfected with human FasL
• splenic dendritic cells are resistant to apoptosis in vivo initiated by cognate OT-1 T cells

hematopoietic system
• dendritic cell number increases with age in the spleen
• mice exhibit histological changes in the spleen

• mice have hyperimmunoglobulinemia

growth/size/body
