mortality/aging
• mice die of a wasting autoimmune disease starting 15 weeks after transfer of nave wild-type CD4 T cells

immune system
• proportion of and absolute number of CD117++ double negative (CD44+CD25-) cells among thymocytes is reduced
• severe block in T cell development
• T cells are absent in these mice
• with increasing age, the number of thymic B cells remains constant, however proportion of pro/pre-B cells is decreased with time
• mice exhibit symptoms of an autoimmune disorder starting 12 weeks after transfer of nave wild-type CD4 T Cells
• however, mice fail to develop signs of wasting disease after transfer of wild-type CD25-positive CD4 T cells

hematopoietic system
• proportion of and absolute number of CD117++ double negative (CD44+CD25-) cells among thymocytes is reduced

neoplasm
• leukemia tumor development penetrance is 87%
• mice intraperitonally injected with MMLV show accelerated pre-B-cell leukemia formation compared to controls
• 40% of mice develop B-cell acute lymphoblastic leukemia
• however, mice do not develop T-cell acute lymphoblastic leukemia, myeloid leukemia, or mixed B-cell/myeloid leukemia
• B-cell leukemia development is accelerated compared to single Tg(Tcrb-TCF3/PBX1)23Gusa transgenic mice
• B-cell tumors are B220+/CD43-/CD19+/IgM-/Pax5+, indicating a pre-B-cell phenotype, and contain IgH chain rearrangements, mostly of the kappa light chain
