The molecular mechanisms whereby these pathogenic factors are regulated during the disease are not fully understood. We report in this article that a member of the TNF-\u03b1\u2013induced protein 8 (TNFAIP8) family called TIPE2 (TNFAIP8-like 2) plays a crucial role in regulating commensal bacteria dissemination and inflammatory cell function in experimental colitis induced by dextran sodium sulfate (DSS). Following DSS treatment, TIPE2-deficient mice, or chimeric mice that are deficient in TIPE2 only in their hematopoietic cells, lost less body weight and survived longer than wild-type controls. Consistent with this clinical observation, TIPE2-deficient mice exhibited significantly less severe colitis and colonic damage. This was associated with a marked reduction in the colonic expression of inflammatory cytokines, such as TNF-\u03b1, IL-6, and IL-12. Importantly, the ameliorated DSS-induced colitis in TIPE2\u2212\/\u2212 mice also was associated with reduced local dissemination of commensal bacteria and a weaker systemic inflammatory response. Combined with our previous report that TIPE2 is a negative regulator of antibacterial immunity, these results indicate that TIPE2 promotes colitis by inhibiting mucosal immunity to commensal bacteria.<\/jats:p>","DOI":"10.4049\/jimmunol.1400415","type":"journal-article","created":{"date-parts":[[2014,6,28]],"date-time":"2014-06-28T04:11:48Z","timestamp":1403928708000},"page":"1064-1070","source":"Crossref","is-referenced-by-count":45,"title":["Critical Roles of TIPE2 Protein in Murine Experimental Colitis"],"prefix":"10.1093","volume":"193","author":[{"given":"Yunwei","family":"Lou","sequence":"first","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, University of Pennsylvania Perelman School of Medicine , Philadelphia, PA, 19104"},{"name":"Department of Immunology, Shandong University School of Medicine , Ji\u2019nan 250012 ,","place":["People\u2019s Republic of China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Honghong","family":"Sun","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, University of Pennsylvania Perelman School of Medicine , Philadelphia, PA, 19104"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Samantha","family":"Morrissey","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, University of Pennsylvania Perelman School of Medicine , Philadelphia, PA, 19104"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Porturas","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, University of Pennsylvania Perelman School of Medicine , Philadelphia, PA, 19104"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Suxia","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Immunology, Shandong University School of Medicine , Ji\u2019nan 250012 ,","place":["People\u2019s Republic of China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xianxin","family":"Hua","sequence":"additional","affiliation":[{"name":"Department of Cancer Biology, University of Pennsylvania Perelman School of Medicine , Philadelphia, PA, 19104"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Youhai H","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, University of Pennsylvania Perelman School of Medicine , Philadelphia, PA, 19104"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2014,8,1]]},"reference":[{"key":"2025030707275772600_r1","doi-asserted-by":"crossref","first-page":"514","DOI":"10.1172\/JCI30587","article-title":"The fundamental basis of inflammatory bowel disease","volume":"117","author":"Strober","year":"2007","journal-title":"J.
