Inherited immunodeficiencies associated with proximal and distal defects in T cell receptor signaling and co-signaling

open access: yesBiomedical Journal, 2022
T lymphocytes are central cells of adaptive immunity. Activation of T lymphocytes by the antigen receptor of T cells (TCR) and co-stimulatory molecules involve specific signaling components and cascades.

Tuning of in vivo cognate B-T cell interactions by Intersectin 2 is required for effective anti-viral B cell immunity

open access: yeseLife, 2018
Wiskott-Aldrich syndrome (WAS) is an immune pathology associated with mutations in WAS protein (WASp) or in WASp interacting protein (WIP). Together with the small GTPase Cdc42 and other effectors, these proteins participate in the remodelling of the ...

Dynamic changes of mmp-9 plasma levels correlate with jvc reactivation and immune activation in natalizumab-treated multiple sclerosis patients [PDF]

open access: yes, 2019
The aim of the study was to investigate the changes of matrix metalloproteinase (MMP)-2 and MMP-9 plasma levels during natalizumab treatment and their correlation with JC virus (JCV) reactivation and T-lymphocyte phenotypic modifications in peripheral ...

Loss of RASGRP1 in humans impairs T‐cell expansion leading to Epstein‐Barr virus susceptibility

open access: yesEMBO Molecular Medicine, 2018
Inherited CTPS1, CD27, and CD70 deficiencies in humans have revealed key factors of T‐lymphocyte expansion, a critical prerequisite for an efficient immunity to Epstein–Barr virus (EBV) infection.

Can follicular helper T cells be targeted to improve vaccine efficacy? [version 1; referees: 3 approved]

open access: yesF1000Research, 2016
The success of most vaccines relies on the generation of antibodies to provide protection against subsequent infection; this in turn depends on a robust germinal centre (GC) response that culminates in the production of long-lived antibody-secreting ...

Coordinating Cytoskeleton and Molecular Traffic in T Cell Migration, Activation, and Effector Functions

open access: yesFrontiers in Cell and Developmental Biology, 2020
Dynamic localization of receptors and signaling molecules at the plasma membrane and within intracellular vesicular compartments is crucial for T lymphocyte sensing environmental cues, triggering membrane receptors, recruiting signaling molecules, and ...

T-follicular regulatory cells expand to control germinal center plasma cell output but fail to curb autoreactivity

open access: yesiScience
Summary: Autoantibodies generated in germinal centers (GCs) contribute to the pathogenesis of autoimmune diseases. GCs are controlled by specialized FoxP3+ T-follicular regulatory cells (Tfr), but their role in established autoimmunity is unclear.

RNA editing generates cellular subsets with diverse sequence within populations

open access: yesNature Communications, 2016
RNA editing rate detected from bulk RNA-seq data can vary widely. Here, by constructing a hierarchical Bayesian model, the authors report substantial variance in editing signatures detected by RNA-seq data from both single cells and a cognate bulk sample.

Cellular Stress in the Context of an Inflammatory Environment Supports TGF-β-Independent T Helper-17 Differentiation

open access: yesCell Reports, 2017
T helper-17 (Th17) cells are associated with inflammatory disorders and cancer. We report that environmental conditions resulting in cellular stress, such as low oxygen, glucose, and isotonic stress, particularly enhance the generation of Th17 cells ...

Self-renewal of double-negative 3 early thymocytes enables thymus autonomy but compromises the β-selection checkpoint

open access: yesCell Reports, 2021
Summary: T lymphocyte differentiation in the steady state is characterized by high cellular turnover whereby thymocytes do not self-renew. However, if deprived of competent progenitors, the thymus can temporarily maintain thymopoiesis autonomously.
