In-depth analysis of human virus-specific CD8+ T cells delineates unique phenotypic signatures for T cell specificity prediction

open access: yesCell Reports, 2023
Summary: Following viral infection, the human immune system generates CD8+ T cell responses to virus antigens that differ in specificity, abundance, and phenotype.

CD8 Co-Receptor Enhances T-Cell Activation without Any Effect on Initial Attachment

open access: yesCells, 2021
The scanning of surrounding tissues by T lymphocytes to detect cognate antigens requires high speed, sensitivity and specificity. T-cell receptor (TCR) co-receptors such as CD8 increase detection performance, but the exact mechanism remains incompletely ...

Non-antigen specific CD8+ T suppressor lymphocytes

open access: yesClinical and Experimental Medicine, 2004
The homeostasis of peripheral immune system function is maintained by the activity of regulatory lymphocytes. Among these cells, a subset of CD8+CD28- T suppressor lymphocytes has recently been characterized for the capacity to mediate their effects without antigen restriction.

Analysis of TCR Repertoire and PD-1 Expression in Decidual and Peripheral CD8+ T Cells Reveals Distinct Immune Mechanisms in Miscarriage and Preeclampsia

open access: yesFrontiers in Immunology, 2020
CD8+ T cells, the most abundant T cell subset in the decidua, play a critical role in the maintenance of pregnancy. The majority of decidual CD8+ T cells have an effector memory phenotype, while those in the peripheral blood display a naive phenotype. An

Dendritic Cells and CD8 T Cell Immunity in Tumor Microenvironment

open access: yesFrontiers in Immunology, 2018
Dendritic cells (DCs) play a central role in the regulation of the balance between CD8 T cell immunity vs. tolerance to tumor antigens. Cross-priming, a process which DCs activate CD8 T cells by cross-presenting exogenous antigens, plays a critical role ...

Autoregulatory CD8 T cells depend on cognate antigen recognition and CD4/CD8 myelin determinants [PDF]

open access: yesNeurology Neuroimmunology & Neuroinflammation, 2015
To determine the antigenic determinants and specific molecular requirements for the generation of autoregulatory neuroantigen-specific CD8(+) T cells in models of multiple sclerosis (MS).We have previously shown that MOG35-55-specific CD8(+) T cells suppress experimental autoimmune encephalomyelitis (EAE) in the C57BL/6 model.

Proteogenomic identification of an immunogenic antigen derived from human endogenous retrovirus in renal cell carcinoma

open access: yesJCI Insight, 2023
CD8+ T cells can recognize tumor antigens displayed by HLA class I molecules and eliminate tumor cells. Despite their low tumor mutation burden, immune checkpoint blockade (ICB) is often beneficial in patients with renal cell carcinoma (RCC). Here, using

Antigen delivery to dendritic cells shapes human CD4+ and CD8+ T cell memory responses to Staphylococcus aureus. [PDF]

open access: yesPLoS Pathogens, 2017
Intracellular persistence of Staphylococcus aureus favors bacterial spread and chronic infections. Here, we provide evidence for the existence of human CD4+ and CD8+ T cell memory against staphylococcal antigens.

Antigen and Memory CD8 T Cells: Were They Both Right? [PDF]

open access: yesAllergy, Asthma, and Clinical Immunology, 2007
Abstract Picture yourself as a researcher in immunology. To begin your project, you ask a question: Do CD8 T cells require antigen to maintain a memory response? This question is of prime importance to numerous medical fields. In chronologic order, you digest the literature, but unfortunately, you hit a major stumbling block in the 1990s. The

Quantitation of antigen-specific CD8+ T-cell responses

open access: yesImmunology Letters, 1999
Enumeration of antigen-specific CD8+ T-cells has traditionally been largely dependent on the use of techniques that require a period of expansion in vitro. However the recent emergence of methods that can be used directly ex vivo to quantify antigen-specific CD8+ T cells has prompted a re-evaluation of the magnitude of viral-specific cellular immune ...
