MAIT Cells Suppress IgE‐Mediated Asthma via IFNγ‐Dependent B Cell Regulation

Allergy, EarlyView.
In this study, we demonstrate that MAIT cell antagonism during sensitization and challenge with HDM worsens the development of airway hyperreactivity without effects on type 2 or 17 associated cytokine production or lung inflammation. Rather, MAIT cells appear to regulate HDM‐induced asthma through direct inhibition of IgE production.

An overview on the identification of MAIT cell antigens [PDF]

Immunology & Cell Biology, 2018
AbstractMucosal associated invariant T (MAIT) cells are restricted by the monomorphic MHC class I‐like molecule, MHC‐related protein‐1 (MR1). Until 2012, the origin of the MAIT cell antigens (Ags) was unknown, although it was established that MAIT cells could be activated by a broad range of bacteria and yeasts, possibly suggesting a conserved Ag ...

Hantaan virus infection induces human mucosal-associated invariant T cell pyroptosis through IRE1α pathway

Communications Biology
Hantaan virus (HTNV) triggers an epidemic of hemorrhagic fever with renal syndrome (HFRS), which is predominantly prevalent in Asia. Mucosal-associated invariant T (MAIT) cells, categorized as innate-like T lymphocytes, perform crucial functions in the ...

Sex discrepancy in the reduction of mucosal‐associated invariant T cells caused by obesity

Immunity, Inflammation and Disease, 2021
Introduction Gut microbiota has been reported to contribute to obesity and the pathology of obesity‐related diseases but the underlying mechanisms are largely unknown.

A Unified Machine Learning Model for Relapse Prediction in Clinical Stage I Testicular Cancer

Andrology, EarlyView.
ABSTRACT Background Approximately one‐fourth of patients with clinical stage I testicular cancer relapse. For decades, risk stratification has been based on different tumor characteristics for seminomas and non‐seminomas. Previous studies primarily used Cox proportional‐hazards models and included only a limited number of variables.

Characterisation of mucosal associated invariant T-cells and MR1 in ruminants [PDF]

, 2010
Mucosal associated invariant T-cells (MAIT) are a phylogenetically conserved subset of alpha/beta T-cells with natural killer-like (NK) activity. MAIT are defined by the expression of an invariant T-cell receptor alpha (TCRα) chain; in mice and humans ...

Infection control in the brain and the eye

Acta Ophthalmologica, EarlyView.
Abstract The Central Nervous System (CNS), comprising the brain and the eye, is considered to have a ‘privileged’ mechanism for dealing with immunological challenge (immune privilege, IP). CNS IP has been revealed through experiments using foreign protein antigens and cell and tissue alloantigens (grafts), but evidence for a role for IP in modulating ...

HIV-Infected Children Have Lower Frequencies of CD8+ Mucosal-Associated Invariant T (MAIT) Cells that Correlate with Innate, Th17 and Th22 Cell Subsets. [PDF]

PLoS ONE, 2016
Mucosal-associated invariant T cells (MAIT) are innate T cells restricted by major histocompatibility related molecule 1 (MR1) presenting riboflavin metabolite ligands derived from microbes.

Mucosal-associated invariant T cells in patients with axial spondyloarthritis

Frontiers in Immunology, 2023
BackgroundSeveral studies implicate Th17-cells and its cytokine (IL-17) in disease pathogenesis of spondyloarthritis (SpA), with available evidence supporting a pathogenic role of CD8+ T-cells.

Characterising MAIT cells in human mucosal cancers

, 2021
Mucosal associated invariant T cells (MAIT cells) are MR1-restricted T cells that regulate the local immune milieu with cytotoxic and cytokine responses.
