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
|
