1 The Induction of Pro-IL-1beta by Lipopolysaccharide Requires Endogenous Prostaglandin E2 Production. Dinoprostone interleukin 1 beta Homo sapiens
2 PGE2 has been shown to increase the transcription of pro-IL-1beta. Dinoprostone interleukin 1 beta Homo sapiens
3 However, recently it has been demonstrated that PGE2 can block the maturation of IL-1beta by inhibiting the NLRP3 inflammasome in macrophages. Dinoprostone interleukin 1 beta Homo sapiens
4 These apparently conflicting results have led us to reexamine the effect of PGE2 on IL-1beta production. Dinoprostone interleukin 1 beta Homo sapiens
5 We have found that in murine bone marrow-derived macrophages, PGE2 via the cAMP/protein kinase A pathway is potently inducing IL-1beta transcription, as well as boosting the ability of LPS to induce IL-1beta mRNA and pro-IL-1beta while inhibiting the production of TNF-alpha. Dinoprostone interleukin 1 beta Homo sapiens
6 We also examined the effect of endogenously produced PGE2 on IL-1beta production. Dinoprostone interleukin 1 beta Homo sapiens
7 By blocking PGE2 production with indomethacin, we made a striking finding that endogenous PGE2 is essential for LPS-induced pro-IL-1beta production, suggesting a positive feedback loop. Dinoprostone interleukin 1 beta Homo sapiens
8 By blocking PGE2 production with indomethacin, we made a striking finding that endogenous PGE2 is essential for LPS-induced pro-IL-1beta production, suggesting a positive feedback loop. Dinoprostone interleukin 1 beta Homo sapiens
9 In primary human monocytes, where LPS alone is sufficient to induce mature IL-1beta, PGE2 boosted LPS-induced IL-1beta production. Dinoprostone interleukin 1 beta Homo sapiens
10 In primary human monocytes, where LPS alone is sufficient to induce mature IL-1beta, PGE2 boosted LPS-induced IL-1beta production. Dinoprostone interleukin 1 beta Homo sapiens
11 Because PGE2 mediates the pyrogenic effect of IL-1beta, these effects might be especially relevant for the role of monocytes in the induction of fever. Dinoprostone interleukin 1 beta Homo sapiens
12 A positive feedback loop from IL-1beta and back to PGE2, which itself is induced by IL-1beta, is likely to be operating. Dinoprostone interleukin 1 beta Homo sapiens
13 A positive feedback loop from IL-1beta and back to PGE2, which itself is induced by IL-1beta, is likely to be operating. Dinoprostone interleukin 1 beta Homo sapiens
