Differential regulation of interleukin-12 and interleukin-10 by heat shock response in murine peritoneal macrophages
2001
Heat shock response is a conserved stress response and has been shown to have anti-inflammatory effects. We investigated the effect of heat shock response on LPS-induced production of IL-12 and IL-10, which are two important cytokines playing contradictory roles in regulation of immune response, by murine peritoneal macrophages. The data showed that induction of heat shock response strongly suppressed LPS-induced production of IL-12 while augmented that of IL-10, suggesting the pleiotropic effects of heat shock response on immune regulatory gene expression. Also, the novel observation on up-regulation of IL-10 by heat shock response adds to the mechanism by which heat shock response exerts its anti-inflammatory effects. (C) 2001 Academic Press.
