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

Monocyte inflammation and adaptive immune dysfunction in severe Klebsiella pneumoniae pneumonia
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 ...

Varicella Zoster Virus disrupts MAIT cell polyfunctional effector responses.
Mucosal-associated invariant T (MAIT) cells are unconventional T cells that respond to riboflavin biosynthesis and cytokines through TCR-dependent and -independent pathways, respectively.

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

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.

Chronic HIV infection causes systemic immune activation and dysregulation, resulting in the impairment of most T-cell subsets including MAIT cells. Multiple human cohort studies demonstrate MAIT cells are selectively depleted in the peripheral blood and ...

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.

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

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