Summary, Etc.  
요약Mucosal infections, such as those that cause disease in the gastrointestinal and respiratory tracts, account for millions of deaths annually. One way to combat mucosal infections is through mucosal-administered vaccines. Mucosal vaccines offer benefits over systemic vaccines because they can elicit mucosal-specific protection, have less risk of disease transmission, and are lower in cost. Despite these benefits, there remain a limited number of mucosal vaccines, which often have limited long-term efficacy. This is partially due to the lack of licensed mucosal adjuvants. Potential targets for mucosal adjuvants are unconventional T cells, including mucosal-associated invariant T (MAIT) cells. MAIT cells are innate-like αβ T cells whose T cell receptor (TCR) recognizes riboflavin synthesis intermediates presented on the MHC-I-related protein 1 (MR1). MAIT cells are enriched in human blood and mucosal surfaces and are potent producers of pro-inflammatory cytokines and cytotoxic molecules. Recent studies have highlighted a potential role for MAIT cells in B cell help. However, the mechanisms of MAIT-B cell help and whether MAIT cells may be suitable targets for mucosal vaccine adjuvants remain unknown. This dissertation uncovers a novel MAIT population with the capacity for B cell help, and uses mouse and organoid models to study the adjuvant potential of MAIT ligands in mucosal vaccination.Chapter 2 identifies a population of CXCR5-expressing T follicular helper-like MAIT cells (MAITFH). MAITFH cells are enriched near germinal centers of human tonsils and express B cell help co-stimulatory markers and cytokines, including interleukin-21. MAIT cells are further shown to be sufficient to rescue pathogen-specific IgA antibody responses following adoptive transfer into T cell-deficient mice vaccinated with live Vibrio cholerae. Chapter 3 investigates whether the MAIT ligand, 5-OP-RU, is an effective adjuvant for mucosal vaccines in vivo. MAIT ligand treatment significantly expanded MAIT cells in intranasal live V. cholerae and V. cholerae polysaccharide vaccine models. Ligand adjuvanted mice had moderately higher mucosal polysaccharide-specific IgG, which was associated with lung MAIT cell frequency in the polysaccharide vaccine model. However, no differences in humoral immunity were reported with the live V. cholerae vaccine. Preliminary experiments presented in Chapter 4 confirm the adjuvant limitations of MAIT ligand in a human tonsil organoid model while discussing the potential for developing MAIT ligand-polysaccharide conjugate vaccines.
