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.

Commensal bacteria at mucosal surfaces can remotely control the thymic maturation of mucosal-associated invariant T cells through the production of microbial factors that enter the circulation and are taken up by thymic cells.

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 ...

The biology and functional importance of MAIT cells
Nature Immunology, 2019In recent years, a population of unconventional T cells called 'mucosal-associated invariant T cells' (MAIT cells) has captured the attention of immunologists and clinicians due to their abundance in humans, their involvement in a broad range of infectious and non-infectious diseases and their unusual specificity for microbial riboflavin-derivative ...

MAIT cells and MR1-antigen recognition
Current Opinion in Immunology, 2017Mucosal-associated invariant T cells (MAIT cells) are innate-like T cells that recognise antigens presented by the monomorphic MHC-I related molecule, MR1. Distinct from the conventional MHC-restricted T cell system, MR1 presents small-molecule precursors, derived from microbial biosynthesis of riboflavin, to activate the innate MAIT cell effector ...

Deficiency in Peripheral MAIT Cells But Not in Intrahepatic MAIT Cells in Humans with CHBV Infection
SSRN Electronic Journal, 2019Background: Chronic hepatitis B virus (CHBV) infection is a major cause of liver diseases. Mucosal-associated invariant T (MAIT) cells are important for antiviral immunity in the liver, but the distinction between intrasinusoidal MAIT cells and peripheral MAIT cells in patients with CHBV infection remains unclear.

AbstractIn humans, MAIT cells represent the most abundant T‐cell subset reacting against bacteria. MAIT cells belong to the evolutionarily conserved family of “preset” T cells that includes also NKT cells. Both subsets are selected by double positive thymocytes leading to common features such as PLZF expression.

MAIT Cell Activation by Fungal Pathogens
2019MAIT cells can recognize and respond to several pathogens in a distinct manner. However, many studies are focused on activation by bacteria and by viruses, while reports about molds and MAIT cells are rare. Here, we describe a method to investigate MAIT cell interaction with filamentous fungi from Aspergillus and Mucorales species.

Activation and Function of iNKT and MAIT Cells
2015Over the last two decades, it has been established that peptides are not the only antigens recognized by T lymphocytes. Here, we review information on two T lymphocyte populations that recognize nonpeptide antigens: invariant natural killer T cells (iNKT cells), which respond to glycolipids, and mucosal associated invariant T cells (MAIT cells), which ...

Reprogramming of MAIT Cells to Pluripotency and Redifferentiation
2019Reprogramming differentiated cells into induced pluripotent stem cells (iPSCs) consists in dedifferentiation of the cells into the pluripotent state, i.e., stem cells. Since T cells play a pivotal role in our immune system, T cell reprogramming into iPSCs and subsequent redifferentiation of iPSCs toward the original cells hold a great promise for ...
