 In addition , the proliferative advantage of p12 ( I ) - transduced PBMCs was evident mainly at low concentrations of IL - 2 .
IL - 2

 Partial inhibition of p50 and p105 expression by NF - kappa B1 antisense oligonucleotides significantly reduced T - cell proliferation and CD25 / IL - 2R alpha cell surface expression .
IL - 2R

 These results demonstrate that glucocorticoids inhibit preactivated T cells by down - regulating signal transduction through IL - 2R .

IL - 2R
