1 Thus, we tested the hypothesis that histamine inhibits the release of a proinflammatory cytokine, namely TNF, by stimulating the release of an anti-inflammatory cytokine, IL-10. Histamine interleukin 10 Homo sapiens
2 Histamine treatment (10-5 M) increased the release of IL-10 from unstimulated (2.2-fold) and LPS-stimulated (1. Histamine interleukin 10 Homo sapiens
3 Unstimulated AMs, NR8383, express few copies of IL-10 mRNA, as tested by quantitative PCR, but expression of IL-10 was increased by 1.5-fold with histamine treatment. Histamine interleukin 10 Homo sapiens
4 Moreover, the stimulation of IL-10 release by histamine was abrogated by pretreatment with anti-PGE2 or the NO synthase inhibitor, Nomega-nitro-l -arginine methyl ester. Histamine interleukin 10 Homo sapiens
5 Thus, histamine increases the synthesis and release of IL-10 from AMs through PGE2 and NO production. Histamine interleukin 10 Homo sapiens
