CXCL16 Stimulates Antigen-Induced MAIT Cell Accumulation but Trafficking During Lung Infection Is CXCR6-Independent

Frontiers in Immunology, 2020
Mucosa-associated invariant T (MAIT) cells are a unique T cell subset that contributes to protective immunity against microbial pathogens, but little is known about the role of chemokines in recruiting MAIT cells to the site of infection.

B Cells Control Mucosal-Associated Invariant T Cell Responses to Salmonella enterica Serovar Typhi Infection Through the CD85j HLA-G Receptor

Frontiers in Immunology, 2021
Mucosal-associated invariant T (MAIT) cells are an innate-like population of T cells that display a TCR Vα7.2+ CD161+ phenotype and are restricted by the nonclassical MHC-related molecule 1 (MR1).

Monocytes with trained immunity–like signatures are associated with acute anterior uveitis in ankylosing spondylitis

Interdisciplinary Medicine, EarlyView.
In ankylosing spondylitis‐acute anterior uveitis (AS‐AAU), trained immunity monocytes (Mono‐TI) differentiate into macrophages in the eye, retaining trained immunity features. Mono‐TI cells secrete pro‐inflammatory cytokines and chemokines, including IL‐1β, TNF‐α, and CCL3.

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 ...

Herpes simplex virus type 1 impairs mucosal-associated invariant T cells

mBio
Herpes simplex virus type 1 (HSV-1) is a highly successful pathogen that infects mucosal sites and adopts an arsenal of strategies to manipulate host immunity.

MAIT cells are reduced in frequency and functionally impaired in human T lymphotropic virus type 1 infection: Potential clinical implications. [PDF]

PLoS ONE, 2017
HTLV-1 infection is associated with several inflammatory disorders, including the neurodegenerative condition HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). It is unclear why a minority of infected subjects develop HAM/TSP.

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.

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.
