immune system
• the majority of T cells in the thymus are arrested at the double positive stage
• single positive T cells are virtually absent
• however, the TCR transgene rescues the arrestment of T cells in the double negative stage that occurs in Rag2 deficient background
• mature CD4 T cells are severely reduced in the spleen
• mature CD8 T cells are virtually absent in the spleen
