1 Tristetraprolin mediates anti-inflammatory effects of nicotine in lipopolysaccharide-stimulated macrophages. Nicotine ZFP36 ring finger protein Homo sapiens
2 Here we show that in LPS-stimulated human macrophages the anti-inflammatory action of nicotine is mediated by TTP. Nicotine ZFP36 ring finger protein Homo sapiens
3 Nicotine induced activation of STAT3 enhanced STAT3 binding to the TTP promoter, increased TTP promoter activity, and increased TTP expression resulting in the suppression of LPS-stimulated TNF-alpha production. Nicotine ZFP36 ring finger protein Homo sapiens
4 Nicotine induced activation of STAT3 enhanced STAT3 binding to the TTP promoter, increased TTP promoter activity, and increased TTP expression resulting in the suppression of LPS-stimulated TNF-alpha production. Nicotine ZFP36 ring finger protein Homo sapiens
5 Nicotine induced activation of STAT3 enhanced STAT3 binding to the TTP promoter, increased TTP promoter activity, and increased TTP expression resulting in the suppression of LPS-stimulated TNF-alpha production. Nicotine ZFP36 ring finger protein Homo sapiens
6 Overexpression of a dominant negative mutant of STAT3 (R382W) or down-regulation of STAT3 by siRNA abolished nicotine-induced TTP expression and suppression of LPS-stimulated TNF-alpha production. Nicotine ZFP36 ring finger protein Homo sapiens
7 However, siRNA to TTP abrogated these effects of nicotine. Nicotine ZFP36 ring finger protein Homo sapiens
8 In this experiment, we are reporting for the first time the involvement of TTP in the cholinergic anti-inflammatory cascade consisting of nicotine-STAT3-TTP-dampening inflammation. Nicotine ZFP36 ring finger protein Homo sapiens
9 In this experiment, we are reporting for the first time the involvement of TTP in the cholinergic anti-inflammatory cascade consisting of nicotine-STAT3-TTP-dampening inflammation. Nicotine ZFP36 ring finger protein Homo sapiens
