• the presence of the transgene prevents the splenomegaly, the large number of T cells, and high circulating levels of IL-17 normally found in Il2ratm1Dw homozygotes
increased activated T cell number ( J:151722 )
• high expression of CD44 and CD69 suggests the transgene does not prevent the aberrant activation of peripheral T cells
