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

Cells, 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 ...

Antigen-specific acquired immunity in human brucellosis: implications for diagnosis, prognosis, and vaccine development. [PDF]

, 2012
Brucella spp., are Gram negative bacteria that cause disease by growing within monocyte/macrophage lineage cells. Clinical manifestations of brucellosis are immune mediated, not due to bacterial virulence factors.

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

Frontiers 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

Cognate Antigen Stimulation Generates Potent CD8+ Inflammatory Effector T Cells [PDF]

Frontiers in Immunology, 2013
Inflammatory reactions are believed to be triggered by innate signals and have a major protective role by recruiting innate immunity cells, favoring lymphocyte activation and differentiation, and thus contributing to the sequestration and elimination of the injurious stimuli.

Cytotoxic CD8⁺T cells target citrullinated antigens in rheumatoid arthritis

Nature Communications, 2022
AbstractThe immune mechanisms that mediate synovitis and joint destruction in rheumatoid arthritis (RA) remain poorly defined. Although increased levels of CD8+T cells have been described in RA, their role in pathogenesis remains unclear. Here we perform single cell transcriptome and T cell receptor (TCR) sequencing of CD8+T cells derived from anti ...

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

JCI 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

Apoptotic epitope-specific CD8+ T cells and interferon signaling intersect in chronic hepatitis C virus infection [PDF]

, 2015
CD8(+) T cells specific to caspase-cleaved antigens derived from apoptotic T cells represent a principal player in chronic immune activation (CIA). Here, we found that both apoptotic epitope (AE)-specific and hepatitis C virus (HCV)-specific CD8(+) T ...

CD8 T cell ignorance or tolerance to islet antigens depends on antigen dose [PDF]

Proceedings of the National Academy of Sciences, 1999
There are two major mechanisms reported to prevent the autoreactivity of islet-specific CD8+T cells: ignorance and tolerance. When ignorance is operative, naïve autoreactive CD8+T cells ignore islet antigens and recirculate without causing damage, unless activated by an external stimulus. In the case of tolerance, CD8+T cells are deleted.

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

PLoS 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.
