1 Terbutaline (10(-6) M to 10(-8) M) suppressed MAPK (p42/p44, p38), NF-kappa B (p50, p65), and TNF-alpha promoter activity in a dose-dependent way that was prevented by the beta(2)-adrenoceptor antagonist, ICI118,551. Terbutaline interferon induced protein 44 Homo sapiens
2 In summary, the downregulation of TNF-alpha transcription by terbutaline was mediated by an inhibitory effect of beta(2)-adrenoceptor activation on MAPK (p42/p44, p38) and NF-kappa B (p50/p65), which were exerted through a cAMP-PKA pathway and a cAMP-independent mechanism. Terbutaline interferon induced protein 44 Homo sapiens
