Biological functions of MAIT cells in tissues

Molecular Immunology, 2021
Mucosal associated invariant T (MAIT) cells have a recognised innate-like capacity for antibacterial host defence, consequent on the specificity of their T cell receptor (TCR) for small molecule metabolites produced by a range of prokaryotic and fungal species, their effector memory phenotype, and their expression of cytotoxic molecules.

MAIT cells in metabolic diseases

Molecular Metabolism, 2019
Metabolic diseases represent a wide category of alterations affecting metabolism. These pathologies are notably marked by inflammation that implicates the immune system. Mucosal Associated Invariant (MAI)T cells are immune cells expressing a semi-invariant TCR able to recognize bacterial and fungal vitamin B metabolites.

Monkeying around with MAIT Cells: Studying the Role of MAIT Cells in SIV and Mtb Co-Infection [PDF]

Viruses, 2021
There were an estimated 10 million new cases of tuberculosis (TB) disease in 2019. While over 90% of individuals successfully control Mycobacterium tuberculosis (Mtb) infection, which causes TB disease, HIV co-infection often leads to active TB disease.

CD4+/CD8+ mucosa-associated invariant T cells foster the development of endometriosis: a pilot study

Reproductive Biology and Endocrinology, 2019
Background Immune dysregulation is one of the mechanisms to promote endometriosis (EMS). Various T cell subpopulations have been reported to play different roles in the development of EMS.

Peripheral and intestinal mucosal-associated invariant T cells in premature infants with necrotizing enterocolitis

Frontiers in Pharmacology, 2022
Background: Necrotizing enterocolitis (NEC) is a potentially fatal inflammatory gastrointestinal disease in preterm infants with unknown pathogenesis. Mucosal-associated invariant T (MAIT) cells primarily accumulate at sites where exposure to microbes is

Human MAIT Cell Activation In Vitro [PDF]

, 2019
Mucosal-associated invariant T (MAIT) cells are an abundant innate-like T cell subset in humans, enriched in mucosal tissues and the liver. MAIT cells express a semi-invariant T cell receptor (TCR) and recognize microbial-derived riboflavin metabolites presented on the MHC Class I-like molecule MR1. In addition to activation via the TCR, MAIT cells can

Clinicopathological and predictive value of MAIT cells in non-small cell lung cancer for immunotherapy

Journal for ImmunoTherapy of Cancer, 2023
Background Immune-checkpoint inhibitors (ICIs) remain ineffective in a large group of non-small cell lung cancer (NSCLC) patients. Mucosal-associated invariant T (MAIT) cells, a population of unconventional innate-like T lymphocytes abundant in the human

The role of mucosal associated invariant T cells in antimicrobial immunity

Frontiers in Immunology, 2015
Mucosal associated invariant T (MAIT) cells are an innate-like T cell subset prevalent in humans and distributed throughout the blood and mucosal sites. Human MAIT cells are defined by the expression of the semi-invariant TCRα chain TRAV1-2/TRAJ12/20/33 ...

Hyper-Expression of PD-1 Is Associated with the Levels of Exhausted and Dysfunctional Phenotypes of Circulating CD161++TCR iVα7.2+ Mucosal-Associated Invariant T Cells in Chronic Hepatitis B Virus Infection

Frontiers in Immunology, 2018
Mucosal-associated invariant T (MAIT) cells, defined as CD161++TCR iVα7.2+ T cells, play an important role in the innate defense against bacterial infections, and their functionality is impaired in chronic viral infections.
