1 In A549 pulmonary cells, the dexamethasone- and budesonide-dependent repression of interleukin-1beta-induced prostaglandin E2 release was mimicked by the steroid antagonist, RU486. Budesonide interleukin 1 beta Homo sapiens
2 Conversely, whereas dexamethasone and budesonide were highly effective inhibitors of interleukin-1beta-induced cyclooxygenase (COX)/prostaglandin E synthase (PGES) activity and COX-2 expression, RU486 (<1 microm) was a poor inhibitor, but was able to efficiently antagonize the effects of dexamethasone and budesonide. Budesonide interleukin 1 beta Homo sapiens
