The MUC2 mucin is the primary constituent of intestinal mucus and plays critical protective roles against luminal microbes and other noxious agents. In this study, we investigated whether MUC2 helps maintain CD8 T cell tolerance toward intestinal luminal Ags by gavaging wild-type and Muc2\u2212\/\u2212 mice with a model Ag and monitoring immune responses posttreatment. We report that orally delivered OVA rapidly disseminates through the blood of Muc2\u2212\/\u2212 (but not control) mice and causes immune activation of Ag-specific CD8 T cells at both local and distal sites. Further, the administration of oral OVA to Muc2\u2212\/\u2212 mice led to its presentation by thymic dendritic cells and the deletion of Ag-specific thymocytes. Collectively, our findings suggest that intestinal mucus helps limit the shaping of the TCR repertoire of developing thymocytes by intestinal luminal Ags.<\/jats:p>","DOI":"10.4049\/jimmunol.1900687","type":"journal-article","created":{"date-parts":[[2020,6,15]],"date-time":"2020-06-15T19:45:13Z","timestamp":1592250313000},"page":"329-334","source":"Crossref","is-referenced-by-count":4,"title":["Cutting Edge: Intestinal Mucus Limits the Clonal Deletion of Developing T Cells Specific for an Oral Antigen"],"prefix":"10.1093","volume":"205","author":[{"given":"Kevin","family":"Tsai","sequence":"first","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, University of British Columbia , Vancouver, British Columbia V6T 1Z4 ,","place":["Canada"]},{"name":"British Columbia Children\u2019s Hospital Research Institute , Vancouver, British Columbia V5Z 4H4 ,","place":["Canada"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5711-5624","authenticated-orcid":false,"given":"Yu-Hsuan","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, University of British Columbia , Vancouver, British Columbia V6T 1Z4 ,","place":["Canada"]},{"name":"British Columbia Children\u2019s Hospital Research Institute , Vancouver, British Columbia V5Z 4H4 ,","place":["Canada"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Caixia","family":"Ma","sequence":"additional","affiliation":[{"name":"British Columbia Children\u2019s Hospital Research Institute , Vancouver, British Columbia V5Z 4H4 ,","place":["Canada"]},{"name":"Department of Pediatrics, University of British Columbia , Vancouver, British Columbia V6H 3V4 ,","place":["Canada"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0122-3746","authenticated-orcid":false,"given":"Troy A","family":"Baldwin","sequence":"additional","affiliation":[{"name":"Department of Medical Microbiology and Immunology, University of Alberta , Edmonton, Alberta T6G 2S2 ,","place":["Canada"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4847-1285","authenticated-orcid":false,"given":"Kenneth W","family":"Harder","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Immunology, University of British Columbia , Vancouver, British Columbia V6T 1Z3 ,","place":["Canada"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1345-6747","authenticated-orcid":false,"given":"Bruce A","family":"Vallance","sequence":"additional","affiliation":[{"name":"British Columbia Children\u2019s Hospital Research Institute , Vancouver, British Columbia V5Z 4H4 ,","place":["Canada"]},{"name":"Department of Pediatrics, University of British Columbia , Vancouver, British Columbia V6H 3V4 ,","place":["Canada"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8794-6306","authenticated-orcid":false,"given":"John J","family":"Priatel","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, University of British Columbia , Vancouver, British Columbia V6T 1Z4 ,","place":["Canada"]},{"name":"Department of Pediatrics, University of British Columbia , Vancouver, British Columbia V6H 3V4 ,","place":["Canada"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2020,7,15]]},"reference":[{"key":"2025030417504305300_r1","doi-asserted-by":"crossref","first-page":"1982","DOI":"10.1097\/MIB.0000000000000392","article-title":"Extraintestinal manifestations of inflammatory bowel disease","volume":"21","author":"Vavricka","year":"2015","journal-title":"Inflamm.
