Upregulation of interleukin-2 (IL-2)synthesis in accessory cell-depleted T cells by ${\text{O}}_2^{·-}$ or H₂O₂. IL-2 production in Concanavalin-A-stimulated accessory cell-depleted T cell populations in the presence of an ${\text{O}}_2^{-}$-generating system (left panel) or hydrogen peroxide (right panel). For experimental details see Roth & Dröge (1987).
