1 PGE2 Elevates IL-23 Production in Human Dendritic Cells via a cAMP Dependent Pathway. Dinoprostone interleukin 23 subunit alpha Homo sapiens
2 Whether this differential effect of PGE2 on IL-23 production is cell-type- or species-specific has not been investigated in detail. Dinoprostone interleukin 23 subunit alpha Homo sapiens
3 The present study was designed to investigate the effect of PGE2 on IL-23 production in human DCs and the possible underlying mechanisms. Dinoprostone interleukin 23 subunit alpha Homo sapiens
4 Our results demonstrated that PGE2 promoted zymosan-induced IL-23 production in a concentration dependent manner. Dinoprostone interleukin 23 subunit alpha Homo sapiens
5 In addition, it was found that PGE2 is also able to elevate MyD88-mediated IL-23 p19 promoter activity. Dinoprostone interleukin 23 subunit alpha Homo sapiens
6 More importantly, ELISA data demonstrated that db-cAMP, a cAMP analog, and forskolin, an adenylate cyclase activator, can mimic the effect of PGE2 on zymosan-induced IL-23 production, and rp-cAMP, a protein kinase A (PKA) inhibitor, can block the effect of PGE2. Dinoprostone interleukin 23 subunit alpha Homo sapiens
7 More importantly, ELISA data demonstrated that db-cAMP, a cAMP analog, and forskolin, an adenylate cyclase activator, can mimic the effect of PGE2 on zymosan-induced IL-23 production, and rp-cAMP, a protein kinase A (PKA) inhibitor, can block the effect of PGE2. Dinoprostone interleukin 23 subunit alpha Homo sapiens
8 Moreover, PGE2 can increase zymosan-induced expression of the mRNA levels of both p19 and p40 subunits, which was mimicked by db-cAMP and forskolin. Dinoprostone interleukin 23 subunit alpha Homo sapiens
9 Our data suggest that PGE2 elevates the production of IL-23 in human Mo-DCs via a cAMP dependent pathway. Dinoprostone interleukin 23 subunit alpha Homo sapiens
