IL-1beta is an endogenous pyrogen that is induced during systemic lipopolysaccharide (LPS)- or IL-1-induced fever. We have examined the fever and cytokine responses following i.p. injection of IL-1 agonists, IL-1alpha and IL-1beta, and compared these with response to LPS (i.p.) in wild-type and IL-1beta-deficient mice. The IL-1beta deficient mice appear to(More)
Stably transfected HEK-293 cells express on their surface the murine type II IL-1 receptor (mIL-1RII) as demonstrated by FACS analysis using the mAb 4E2, however binding of [125I]-hrIL-1beta to these cells is nearly absent. Saturable high affinity binding of [125I]-hrIL-1beta is observed when the murine IL-1 receptor accessory protein (mIL-1RAcP) is(More)
The insulin secreting rat Rinm5F cells are often used to study the cytotoxic actions of interleukin-1 (IL-1) on pancreatic beta-cells. We demonstrate here that Rinm5F insulinoma cells express both type I and type II interleukin-1 receptor (IL-1R) mRNAs and gene products. IL-1R agonists, recombinant murine IL-1 alpha (rmIL-1 alpha, 10 ng/ml) and recombinant(More)
The endogenous pyrogen interleukin-1 (IL-1) is considered as one of the key molecules in orchestrating the host response of injury and inflammation. IL-1 exerts its effects upon binding to the type I IL-1 receptor (IL-1RI). The IL-1-IL-1RI complex is further thought to associate with the IL-1 receptor accessory protein (IL-1RAcP), which is suggested to be(More)
The interleukin-1 (IL-1) system possesses two distinct receptors (type I and type II) which, together with the accessory protein, mediate a multitude of responses to IL-1 alpha and IL-1 beta, including fever. So far, no receptor subtype-specific ligands have been described. Since both types of IL-1 receptors occur in the thermoregulatory areas it was(More)
The cytokine interleukin 1 (IL-1) plays an important role in the activation of the hypothalamus-pituary-adrenal (HPA)-axis and interleukin 6 (IL-6) production during infection or inflammation. Which of the interleukin-1 receptor types mediates these effects is not known. To investigate this issue a pharmacological approach was chosen by using recently(More)
