Acute stimulation of nucleotide-binding oligomerization domain 2 (NOD2), the Crohn\u2019s disease\u2013associated sensor of bacterial peptidoglycan, induces cytokines. However, chronic NOD2 stimulation in macrophages decreases cytokines upon pattern recognition receptor (PRR) restimulation; cytokine attenuation to PRR stimulation is similarly observed in intestinal macrophages. The role for the transcriptional repressors Twist1 and Twist2 in regulating PRR-induced cytokine outcomes is poorly understood and has not been reported for NOD2. We found that Twist1 and Twist2 were required for optimal cytokine downregulation during acute and, particularly, chronic NOD2 stimulation of human macrophages. Consistently, Twist1 and Twist2 expression was increased after chronic NOD2 stimulation; this increased expression was IL-10 and TGF-\u03b2 dependent. Although Twist1 and Twist2 did not coregulate each other\u2019s expression, they cooperated to enhance binding to cytokine promoters after chronic NOD2 stimulation. Moreover, Twist1 and Twist2 contributed to enhance expression and promoter binding of the proinflammatory inhibitor c-Maf and the transcriptional repressor Bmi1. Restoring c-Maf and Bmi1 expression in Twist-deficient macrophages restored NOD2-induced cytokine downregulation. Furthermore, with chronic NOD2 stimulation, Twist1 and Twist2 contributed to the decreased expression and cytokine promoter binding of the transcriptional activators activating transcription factor 4, C\/EBP\u03b1, Runx1, and Runx2. Knockdown of these transcriptional activators in Twist-deficient macrophages restored cytokine downregulation after chronic NOD2 stimulation. Finally, NOD2 synergized with additional PRRs to increase Twist1 and Twist2 expression and Twist-dependent pathways. Therefore, after chronic NOD2 stimulation Twist1 and Twist2 coordinate the regulation of both transcriptional activators and repressors, thereby mediating optimal cytokine downregulation.<\/jats:p>","DOI":"10.4049\/jimmunol.1402808","type":"journal-article","created":{"date-parts":[[2015,5,28]],"date-time":"2015-05-28T12:50:29Z","timestamp":1432817429000},"page":"217-226","source":"Crossref","is-referenced-by-count":23,"title":["Twist1 and Twist2 Contribute to Cytokine Downregulation following Chronic NOD2 Stimulation of Human Macrophages through the Coordinated Regulation of Transcriptional Repressors and Activators"],"prefix":"10.1093","volume":"195","author":[{"given":"Shasha","family":"Zheng","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Yale University , New Haven, CT 06520"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matija","family":"Hedl","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Yale University , New Haven, CT 06520"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Clara","family":"Abraham","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Yale University , New Haven, CT 06520"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2015,7,1]]},"reference":[{"key":"2025030703393706300_r1","doi-asserted-by":"crossref","first-page":"2066","DOI":"10.1056\/NEJMra0804647","article-title":"Inflammatory bowel disease","volume":"361","author":"Abraham","year":"2009","journal-title":"N.
