hematopoietic system
abnormal thymus development ( J:91369 )
• Cbl inactivation in Lat deficient mice partially rescues thymic development; ~24% double positive and and 7% CD4 single positive cells are detected in the thymi of double mutants but not in Lat-null animals
thymus hypoplasia ( J:91369 )
• thymus cellularity of double knockout mice is 5% that of wild-type
increased CD4-positive, alpha-beta T cell number ( J:91369 )
• 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

immune system
enlarged spleen ( J:91369 )
• 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
abnormal T cell differentiation ( J:91369 )
• 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
increased CD4-positive, alpha-beta T cell number ( J:91369 )
• 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
abnormal cytokine secretion ( J:91369 )
• many more CD4+ cells produce Il-2, Il-4 and Ifng compared to wild-type
liver inflammation ( J:91369 )
• extensive lymphocyte infiltration is observed in the liver of mutants; lymphocytes are observed as clusters around hepatic parenchyma
lung inflammation ( J:91369 )
• extensive lymphocyte infiltration is observed in the lungs of mutants; lymphocytes are observed as clusters around pulmonary vessels and bronchioles
