Selective and cross-reactive SARS-CoV-2 T cell epitopes in unexposed humans

open access: yesScience, 2020
Preexisting immune response to SARS-CoV-2 Robust T cell responses to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus occur in most individuals with coronavirus disease 2019 (COVID-19). Several studies have reported that some people

A novel CCM2 gene mutation associated with family cerebral cavernous malformation

open access: yesFrontiers in Aging Neuroscience, 2016
Background: Cerebral cavernous malformations (CCMs) are common vascular malformations that predominantly arise in the central nervous system and are mainly characterized by enlarged vascular cavities without intervening brain parenchyma.

Human naive CD8 T cells down-regulate expression of the WNT pathway transcription factors lymphoid enhancer binding factor 1 and transcription factor 7 (T cell factor-1) following antigen encounter in vitro and in vivo [PDF]

open access: yes, 2006
The transcription factors lymphoid enhancer binding factor 1 (LEF1) and transcription factor 7 (TCF7) (T cell factor-1 (TCF-1)) are downstream effectors of the WNT signaling pathway, which is a critical regulator of T cell development in the thymus.

Metabolic regulation of regulatory T cell development and function [PDF]

open access: yes, 2014
It is now well established that the effector T cell (Teff) response is regulated by a series of metabolic switches. Quiescent T cells predominantly require ATP-generating processes, whereas proliferating Teff require high metabolic flux through growth ...

Destabilizing the autoinhibitory conformation of Zap70 induces up-regulation of inhibitory receptors and T cell unresponsiveness. [PDF]

open access: yes, 2017
Zap70 plays a critical role in normal T cell development and T cell function. However, little is known about how perturbation of allosteric autoinhibitory mechanisms in Zap70 impacts T cell biology.

Controlling the Immune Suppressor: Transcription Factors and MicroRNAs Regulating CD73/NT5E

open access: yesFrontiers in Immunology, 2018
The NT5E (CD73) molecule represents an ecto-5′-nucleotidase expressed on the cell surface of various cell types. Hydrolyzing extracellular adenosine monophosphate into adenosine and inorganic phosphate, NT5E performs numerous homeostatic functions in ...

Downregulation of HMGB1 in thymoma cells affects T cell differentiation

open access: yesCentral European Journal of Immunology, 2023
Introduction: Thymoma is the most common anterior mediastinal tumor and is closely associated with myasthenia gravis (MG). Our previous study showed that the expression of Th17 cells increased and the expression of Treg decreased in MG-associated thymoma

IL-23 drives a pathogenic T cell population that induces autoimmune inflammation

open access: yesJournal of Experimental Medicine, 2005
Interleukin (IL)-23 is a heterodimeric cytokine composed of a unique p19 subunit, and a common p40 subunit shared with IL-12. IL-12 is important for the development of T helper (Th)1 cells that are essential for host defense and tumor suppression.

Peptide Super-Agonist Enhances T-Cell Responses to Melanoma

open access: yesFrontiers in Immunology, 2019
Recent immunotherapeutic approaches using adoptive cell therapy, or checkpoint blockade, have demonstrated the powerful anti-cancer potential of CD8 cytotoxic T-lymphocytes (CTL).

Tethering of vesicles to the Golgi by GMAP210 controls LAT delivery to the immune synapse

open access: yesNature Communications, 2019
The immune synapse at the interface between T cells and antigen-presenting cells manifests intense vesicular trafficking, but how the vesicles are sorted is still unclear.
