Comparison of dynamic changes in the peripheral CD8+ T cells function and differentiation in ESCC patients treated with radiotherapy combined with anti-PD-1 antibody or concurrent chemoradiotherapy

Frontiers in Immunology, 2022
ObjectiveThe systematic immune status of cancer patients undergoing immunotherapy is little known. We prospectively identified the function and differentiation traits of peripheral CD8+ T cells based on our phase 1b clinical trial (NCT03222440) of ...

CD8+ Regulatory T Cells

Annual Review of Immunology
A wide variety of suppressive pathways have been investigated in efforts to understand the basis for immune tolerance. Although the contribution of CD4 + regulatory T cells (Tregs) to self-tolerance has been extensively studied, less attention has been given to CD8 +

Understanding memory CD8 + T cells [PDF]

Immunology Letters, 2017
Memory CD8+ T cells were originally thought to exist as two populations (effector and central memory). In recent years, a third population called resident memory T cells has been discovered and further to this these populations are being divided into different subtypes. Understanding the function and developmental pathways of memory CD8+ T cells is key

HIV-Specific CD8+ T Cells Exhibit Reduced and Differentially Regulated Cytolytic Activity in Lymphoid Tissue

Cell Reports, 2017
Summary: Elimination of lymphoid tissue reservoirs is a key component of HIV eradication strategies. CD8+ T cells play a critical role in control of HIV, but their functional attributes in lymph nodes (LNs) remain unclear.

PD-L1+CD8+ T cells enrichment in lung cancer exerted regulatory function and tumor-promoting tolerance

iScience, 2022
Summary: Immunotherapy targeting checkpoint blockade to rescue T cells from exhaustion has become an essential therapeutic strategy in treating cancers. Till now, little is known about the PD-L1 graphic pattern and characteristics in CD8+ T cells.

Natural killer cells promote early CD8 T cell responses against cytomegalovirus. [PDF]

, 2007
Understanding the mechanisms that help promote protective immune responses to pathogens is a major challenge in biomedical research and an important goal for the design of innovative therapeutic or vaccination strategies.

CD40L Expression Allows CD8+ T Cells to Promote Their Own Expansion and Differentiation through Dendritic Cells

Frontiers in Immunology, 2017
CD8+ T cells play an important role in providing protective immunity against a wide range of pathogens, and a number of different factors control their activation.

Characterization of CD8 T cell responses in Mycobacterium Tuberculosis infection [PDF]

, 2011
The aim of this project was to compare the breadth and magnitude of CFP10 and ESAT6-specific CD8 T cell responses in individuals with latent Mycobacterium tuberculosis (MTB) infection (LTBI) and active TB disease, and further define MTB-specific CD8 T ...

CD8+ T-cell responses to Theileria parva are preferentially directed to a single dominant antigen:Implications for parasite strain-specific immunity [PDF]

, 2009
Although immunodominance of CD8(+) T-cell responses is a well-recognised feature of viral infections, its role in responses to more antigenically complex pathogens is less clear.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
