1 Prostaglandin E2 inhibits IL-23 and IL-12 production by human monocytes through down-regulation of their common p40 subunit. Dinoprostone interleukin 23 subunit alpha Homo sapiens
2 PGE2 has been shown to elevate the IL-23 production by dendritic cells (DC). Dinoprostone interleukin 23 subunit alpha Homo sapiens
3 Monocytes are also producers of IL-23 but the effect of PGE2 on IL-23 production by human monocytes has hardly been investigated. Dinoprostone interleukin 23 subunit alpha Homo sapiens
4 We show here that PGE2 blocks the production of IL-23 by LPS-stimulated monocytes in an IL-10 and IL-1beta independent manner. Dinoprostone interleukin 23 subunit alpha Homo sapiens
5 These effects of PGE2 were cAMP-dependent since the cAMP enhancer forskolin strongly reduced IL-23 and IL-12 production by monocytes. Dinoprostone interleukin 23 subunit alpha Homo sapiens
6 Taken together, PGE2 acts in an anti-inflammatory manner by lowering IL-23 production by monocytes while it has the opposite effect in DC. Dinoprostone interleukin 23 subunit alpha Homo sapiens
