immune system
increased T cell apoptosis ( J:140121 )
• massive cell death of double negative as well as CD4+ and/or CD8+ thymocytes occur in these mice
thymus hypoplasia ( J:140121 )
• thymic cellularity is reduced by about 5-fold compared to transgenic Rag1 null mice
decreased double-positive T cell number ( J:140121 )
• double-positive T cells are absent in the thymus
arrested T cell differentiation ( J:140121 )
• T cells are arrested in the DN3 stage
