Although these studies raise the possibility that IL-17A may influence allergic disease, the mechanism remains unknown. We previously demonstrated that IL-17A mediates CC chemokine (CCL11) production from human airway smooth muscle (ASM) cells. In this study, we demonstrate that STAT3 activation is critical in IL-17A-mediated CCL11 expression in ASM cells. IL-17A mediated a rapid phosphorylation of STAT3 but not STAT6 or STAT5 in ASM cells. Interestingly, transient transfection with wild-type or mutated CCL11 promoter constructs showed that IL-17A-mediated CCL11 expression relies on the STAT6 binding site. However, STAT3 but not STAT6 in vivo binding to the CCL11 promoter was detected following IL-17A stimulation of ASM cells. Overexpression of DN STAT3 (STAT3\u03b2) abolishes IL-17A-induced CCL11 promoter activity. This effect was not observed with STAT6 DN or the STAT3 mutant at Ser727. Interestingly, disruption of STAT3 activity with the SH2 domain binding peptide, but not with control peptide, results in a significant reduction of IL-17A-mediated STAT3 phosphorylation and CCL11 promoter activity. IL-17A-mediated CCL11 promoter activity and mRNA were significantly diminished in STAT3- but not STAT6-silenced ASM cells. Finally, IL-17A-induced STAT3 phosphorylation was sensitive to pharmacological inhibitors of JAK2 and ERK1\/2. Taken together, our data provide the first evidence of IL-17A-mediated gene expression via STAT3 in ASM cells. Collectively, our results raise the possibility that the IL-17A\/STAT3 signaling pathway may play a crucial role in airway inflammatory responses.<\/jats:p>","DOI":"10.4049\/jimmunol.0801882","type":"journal-article","created":{"date-parts":[[2009,3,5]],"date-time":"2009-03-05T20:01:20Z","timestamp":1236283280000},"page":"3357-3365","source":"Crossref","is-referenced-by-count":65,"title":["Critical Role for STAT3 in IL-17A-Mediated CCL11 Expression in Human Airway Smooth Muscle Cells"],"prefix":"10.1093","volume":"182","author":[{"given":"Ali","family":"Saleh","sequence":"first","affiliation":[{"name":"Department of Immunology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lianyu","family":"Shan","sequence":"additional","affiliation":[{"name":"Department of Immunology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew J","family":"Halayko","sequence":"additional","affiliation":[{"name":"Department of Physiology, University of Manitoba , Winnipeg, Manitoba,","place":["Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sam","family":"Kung","sequence":"additional","affiliation":[{"name":"Department of Immunology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdelilah S","family":"Gounni","sequence":"additional","affiliation":[{"name":"Department of Immunology"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2009,3,15]]},"reference":[{"key":"2026012807051599300_R1","first-page":"713","article-title":"Cytokines induce airway smooth muscle cell hyperresponsiveness to contractile agonists.","volume-title":"Thorax","year":"1998"},{"key":"2026012807051599300_R2","first-page":"209","article-title":"Mechanisms of inflammation-mediated airway smooth muscle plasticity and airways remodeling in asthma.","volume-title":"Respir.
