Gt(ROSA)26Sortm2(Lmp1/CD40)Uzs/Gt(ROSA)26Sor+ Cd19tm1(cre)Cgn/Cd19+ mice develop mono- and oligoclonal lymphomas

immune system
• at 8 weeks
• extreme in mice older than 12 months showing signs of disease
• 3.5-fold at 8 weeks
• 20- to 40-fold in mice older than 12 months showing signs of disease
• 8 times more in the spleen
• 4-fold in lymph nodes
• increased percent of IgM+IgD+ B cells in the spleen and lymph nodes
• however, absolute numbers in the bone marrow are normal
• 3 times more in the spleen
• prolonged survival in vitro
• Ig class switch recombination is achieved in the presence of IL4 indicating constitutive CD40 signaling
• activated B cells in the spleen and lymph node
• activated T cells with a shift toward activated and memory-type T cells
• in mice older than 12 months showing signs of disease
• following immunization with hapten conjugated to the carrier chicken gammaglobulin, mice exhibit reduced recruitment/maintenance of B cells within the germinal centers of the spleen compared with wild-type mice

neoplasm
• with extreme splenomegaly, enlarged inguinal lymph nodes, hepatomegaly and nodular infiltrates in the kidney, lung and liver in mice older than 12 months showing signs of disease

liver/biliary system
• in mice older than 12 months showing signs of disease

hematopoietic system
• at 8 weeks
• extreme in mice older than 12 months showing signs of disease
• 3.5-fold at 8 weeks
• 20- to 40-fold in mice older than 12 months showing signs of disease
• 8 times more in the spleen
• 4-fold in lymph nodes
• increased percent of IgM+IgD+ B cells in the spleen and lymph nodes

growth/size/body
• in mice older than 12 months showing signs of disease
• at 8 weeks
