immune system
• mice develop progressive splenomegaly with age and die at ~6 months of age: mutants have 8-12 times the number of splenic CD4+ cells compared to wild-type
• double knockouts generate significant proportions of double positive and Cd4+CD8- T cells compared to Lcp knockouts; these populations are significantly lower than those expected in wild-type or Cbl-null mice
• expression of CD3 or Tcrb is decreased on thymic CD4+CD8- cells compared to wild-type cells; expression of CD4 and CD69 is increased on double positive and single positive CD4 thymocytes relative to wild-type
• mutants have elevated levels of CD4+ T cells in the spleen and lymph nodes of 6 week old mice compared to wild-type or Cbl-null mice; numbers are ~10x the number observed in wild-type or Cbl-null mice at 24 weeks of age
• many more CD4+ cells produce Il-2, Il-4 and Ifng compared to wild-type
• extensive lymphocyte infiltration is observed in the liver of mutants; lymphocytes are observed as clusters around hepatic parenchyma
• extensive lymphocyte infiltration is observed in the lungs of mutants; lymphocytes are observed as clusters around pulmonary vessels and bronchioles
