Gold-containing drugs continue to be used in the treatment of rheumatoid arthritis, but their mode of action remains unknown. One model to explain gold action is that gold-containing compounds can alter free radical production in cells of the immune system, but direct evidence for this hypothesis has been lacking. In this study we show that auranofin can(More)
We have previously demonstrated that auranofin, at nanomolar concentrations, enhances T cell activation, as measured by IL-2 release and Tac expression. However, it is not clear how enhanced T cell activation might be related to therapeutic value, since rheumatoid arthritis is widely believed to be associated with overactivation of the immune response.

Auranofin, 30–300 nM causes a concentration-dependent potentiation of phytohaemagglutinin (PHA)-induced interleukin-2 (IL-2) release from human peripheral blood mononuclear cells in culture. At concentrations of auranofin between 1 and 3 μM, PHA-stimulated IL-2 release was inhibited, and the drug is cytotoxic at these concentrations. At concentrations of(More)
