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.

A Stable Isopterin Mimic of a Potent Bacterial Stimulant of T Cells

Chemistry – A European Journal, EarlyView.
A microbial metabolite covalently binds immunological protein MR1 to potently activate specific lymphocytes called MAIT cells, but it is too unstable for biological applications. Here, using synthesis, assays, protein crystallography, and computer modelling, we report a water‐stable analogue that activates reporter cells expressing the MAIT T cell ...

MAIT cells: new guardians of the liver [PDF]

Clinical & Translational Immunology, 2016
The liver is an important immunological organ that remains sterile and tolerogenic in homeostasis, despite continual exposure to non‐self food and microbial‐derived products from the gut. However, where intestinal mucosal defenses are breached or in the presence of a systemic infection, the liver acts as a second 'firewall', because of its enrichment ...

Mucosal-Associated Invariant T Cells Develop an Innate-Like Transcriptomic Program in Anti-mycobacterial Responses

Frontiers in Immunology, 2020
Conventional T cells exhibit a delayed response to the initial priming of peptide antigens presented by major histocompatibility complex (MHC) proteins.

Monocyte inflammation and adaptive immune dysfunction in severe Klebsiella pneumoniae pneumonia

iMeta, EarlyView.
Severe Klebsiella pneumoniae pneumonia combines intense inflammation with failure to control infection, yet the cellular basis is unclear. Using a severity‐focused single‐cell atlas of 708,894 peripheral blood mononuclear cells from 100 individuals, complemented by plasma protein measurements and flow cytometry, we show that disease severity redirects ...

Natural Polysaccharides for Rheumatoid Arthritis Therapy: Mechanism, Drug Delivery and Clinical Application

Phytotherapy Research, EarlyView.
Schematic overview of the experimental models, therapeutic mechanisms, drug delivery systems, and clinical potential of natural polysaccharides in rheumatoid arthritis. ABSTRACT Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized primarily by chronic synovitis.

Single‐Cell Profiling Links T‐Cell Accumulation and TH2/TH17 Dynamics to Eosinophilic Esophagitis (EoE) Activity in Children

Allergy, EarlyView.
Active EoE is associated with more and deeper epithelial eosinophil, mast cell, and T cell infiltration; inactive EoE resembles controls. During remission, PPI treatment leaves more tissue resident CD3+ T‐cells than TS. In active EoE, TH2 cells, IL‐10hi Tregs, and CD8+ cytotoxic T cells are enriched, while TH17 cells are relatively depleted.

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 ...

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.
