These conditions suggest that pTreg cell differentiation could be restricted to precise locations such as mucosal surfaces where they may regulate immune responses to harmless antigens such as commensal microbiota and prevent allergic inflammation. Supporting these ideas, \u201cstudies using Rag-1-deficient T-B monoclonal mice sufficient or deficient in FOXP3 demonstrated that TCR transgenic pTreg cells were sufficient to establish mucosal tolerance and control allergic inflammation induced by the model antigen recognized by the TCR\u201d<\/li><\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/edukemy.com\/free-resources-for-upsc?utm_source=Blog&amp;utm_medium=Banner&amp;utm_campaign=Resources\" target=\"_blank\" rel=\"noreferrer noopener\"><img decoding=\"async\" width=\"1280\" height=\"300\" data-src=\"https:\/\/edukemy.com\/blog\/wp-content\/uploads\/2024\/06\/18.png\" alt=\"\" class=\"wp-image-42398 lazyload\" data-srcset=\"https:\/\/edukemy.com\/blog\/wp-content\/uploads\/2024\/06\/18.png 1280w, https:\/\/edukemy.com\/blog\/wp-content\/uploads\/2024\/06\/18-1170x274.png 1170w, https:\/\/edukemy.com\/blog\/wp-content\/uploads\/2024\/06\/18-585x137.png 585w\" data-sizes=\"(max-width: 1280px) 100vw, 1280px\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" style=\"--smush-placeholder-width: 1280px; --smush-placeholder-aspect-ratio: 1280\/300;\" \/><\/a><\/figure>\n\n\n\n<p>For UPSC Prelims Resources,&nbsp;<a href=\"https:\/\/edukemy.com\/upsc-cse-prelims-resource-centre\" target=\"_blank\" rel=\"noreferrer noopener\">Click here<\/a><\/p>\n\n\n\n<p>For Daily Updates and Study Material:<\/p>\n\n\n\n<p>Join our Telegram Channel \u2013&nbsp;<a href=\"https:\/\/t.me\/WithEdukemy4IAS\" target=\"_blank\" rel=\"noreferrer noopener\">Edukemy for IAS<\/a><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>1.
