text: Interestingly, two categories of clones were distinguished based on the effects of GCS on IL-2 production and IL-2R alpha expression and proliferation; 1) In low IL-2 producers << DEX >> blocked IL-2 production and decreased [[ IL-2R alpha ]] expression and proliferation; 2) In high IL-2 producers DEX inhibited IL-2 production partially and enhanced IL-2R alpha expression and proliferation.
