MAIT Cells in Health and Disease
Annual Review of Immunology, 2020Mucosal-associated invariant T (MAIT) cells have been attracting increasing attention over the last few years as a potent unconventional T cell subset. Three factors largely account for this emerging interest. Firstly, these cells are abundant in humans, both in circulation and especially in some tissues such as the liver.

Immunology and Cell Biology, 2018 AbstractMucosal associated invariant T cells (MAIT cells) bear a T cell receptor (TCR) that specifically targets microbially derived metabolites. Functionally, they respond to bacteria and yeasts, which possess the riboflavin pathway, essential for production of such metabolites and which are presented on MR1.

MAIT cells in infectious diseases
Current Opinion in Immunology, 2017In humans, MAIT cells represent the most abundant T cell subset reacting against bacteria. Their frequency in the blood is decreased in a large variety of infectious diseases of either bacterial or viral origin. MAIT cells accumulate at the site of bacterial infection and are protective in experimental infection models.

MAIT cell subtypes in multiple sclerosis
Journal of Neuroimmunology, 2020In patients with multiple sclerosis (MS) and healthy controls (HC) we studied circulating MAIT cells and MAIT cell subtypes expressing CXCR3 and CCR6 by flow cytometry. Absolute numbers of MAIT cells and specifically Tc17-like MAIT cells were lower in patients with primary progressive MS (PPMS) than in controls. Low numbers of Tc17-like MAIT cells were

MAIT cells as attractive vaccine targets
FEBS Letters, 2019Mucosal‐associated invariant T (MAIT) cells are a subset of T cells that perform innate‐like immunity functions upon recognition of small molecule vitamin B metabolites presented by the MHC, class I‐related protein‐1 (MR1). MAIT cells are profuse in humans, but especially abundant in blood, liver, lungs, and mucosal layers.

MAIT cell development in mice and humans
Molecular Immunology, 2021MAIT cells arise in the thymus following rearrangement of a T cell receptor (TCR) reactive against microbial vitamin B2-derived metabolites presented by the MHC-Ib molecule, MR1. Mechanisms that are conserved in mammals ensure the frequent production of MR1-restricted TCRs and the intra-thymic differentiation of MR1-restricted thymocytes into effector ...

Role of MAIT cells in metabolic diseases
Molecular Immunology, 2021MAIT cells are innate-like T cells that are enriched in mucosal sites and tissues including adipose tissue and liver. They play an important role in immunity against microbial pathogens. Recently, it has been reported that MAIT cells could also be important in metabolic diseases and can be involved in setting up and maintaining chronic inflammation. In

Interactions Between MAIT Cells and Dendritic Cells
2019Mucosal-associated invariant T (MAIT) cells recognize intermediates of the vitamin B2 biosynthetic pathway present in a variety of bacteria, presented by the monomorphic MR1 molecules. Because of their central role in shaping adaptive immunity through interaction with dendritic cells (DCs) and B cells, their manipulation can be of translational ...
