Description:
Exposure to microbes during early childhood is associated with protection from immune-mediated diseases such as inflammatory bowel disease (IBD) and asthma. Here, we show that in germ-free (GF) mice, invariant natural killer T (iNKT) cells accumulate in the colonic lamina propria and lung, resulting in increased morbidity in models of IBD and allergic asthma as compared with that of specific pathogen-free mice. This was associated with increased intestinal and pulmonary expression of the chemokine ligand CXCL16, which was associated with increased mucosal iNKT cells. Colonization of neonatal-but not adult-GF mice with a conventional microbiota protected the animals from mucosal iNKT accumulation and related pathology. These results indicate that age-sensitive contact with commensal microbes is critical for establishing mucosal iNKT cell tolerance to later environmental exposures.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3437652/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3437652/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Olszak, Torsten -- An, Dingding -- Zeissig, Sebastian -- Vera, Miguel Pinilla -- Richter, Julia -- Franke, Andre -- Glickman, Jonathan N -- Siebert, Reiner -- Baron, Rebecca M -- Kasper, Dennis L -- Blumberg, Richard S -- AI090102/AI/NIAID NIH HHS/ -- DK034854/DK/NIDDK NIH HHS/ -- DK44319/DK/NIDDK NIH HHS/ -- DK51362/DK/NIDDK NIH HHS/ -- DK53056/DK/NIDDK NIH HHS/ -- DK88199/DK/NIDDK NIH HHS/ -- P30 DK034854/DK/NIDDK NIH HHS/ -- R01 DK044319/DK/NIDDK NIH HHS/ -- R01 DK088199/DK/NIDDK NIH HHS/ -- R37 DK044319/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2012 Apr 27;336(6080):489-93. doi: 10.1126/science.1219328.
