Human MAIT cells endowed with HBV specificity are cytotoxic and migrate towards HBV-HCC while retaining antimicrobial functions

JHEP Reports, 2021
Background & Aims: Virus-specific T cell dysfunction is a common feature of HBV-related hepatocellular carcinoma (HBV-HCC). Conventional T (ConT) cells can be redirected towards viral antigens in HBV-HCC when they express an HBV-specific receptor ...

CD95 co-stimulation blocks activation of naive T cells by inhibiting T cell receptor signaling [PDF]

, 2009
CD95 is a multifunctional receptor that induces cell death or proliferation depending on the signal, cell type, and cellular context. Here, we describe a thus far unknown function of CD95 as a silencer of T cell activation.

Structural and biophysical insights into the role of CD4 and CD8 in T cell activation

Frontiers in Immunology, 2013
T cell receptors (TCRs) recognize peptides presented by MHC molecules (pMHC) on an antigen-presenting cell (APC) to discriminate foreign from self antigens and initiate adaptive immune responses.

Cooperative binding of T cell receptor and CD4 to peptide-MHC enhances antigen sensitivity

Nature Communications, 2022
It is known that the T cell co-receptor CD4 greatly enhances the capacity of T cell receptor (TCR) signalling, triggered by the peptide-bound MHC molecule.

Dual‐Receptor T Cells Expressing One Self‐Restricted TCR [PDF]

Scandinavian Journal of Immunology, 1997
During thymic development, T cells rearrange and express genes encoding clonotypic T‐cell receptors (TCR), and undergo selective events involving interactions between TCR and thymic major histocompatibility complex (MHC) molecules. Recent studies indicate that up to 30% of peripheral T cells may express two TCR, that both TCR on these cells are ...

Activation of the Hedgehog signaling pathway in T-lineage cells inhibits TCR repertoire selection in the thymus and peripheral T-cell activation [PDF]

, 2007
TCR signal strength is involved in many cell fate decisions in the T-cell lineage. Here, we show that transcriptional events induced by Hedgehog (Hh) signaling reduced TCR signal strength in mice.

Visualization and phenotyping of proinflammatory antigen-specific T cells during collagen-induced arthritis in a mouse with a fixed collagen type II-specific transgenic T-cell receptor beta-chain [PDF]

, 2010
Introduction: The Vbeta12-transgenic mouse was previously generated to investigate the role of antigen-specific T cells in collagen-induced arthritis (CIA), an animal model for rheumatoid arthritis. This mouse expresses a transgenic collagen type II (CII)

RNA Helicase DDX21 Controls CD4+ T Cell Proliferation and Promotes Inflammatory Bowel Disease via Translational Control

Advanced Science, EarlyView.
ABSTRACT Inflammatory bowel disease (IBD) is characterized by dysregulated T cell responses. RNA helicases, including DExD‐box helicase 21 (DDX21), are pivotal in RNA metabolism, but their role in T cell‐mediated pathology during IBD remains unclear. Here, we demonstrate that DDX21 expression in CD4+ T cells correlates with cell cycle and translation ...
