Cytomegalovirus Colitis in Primary Hypogammaglobulinemia With Normal CD4+ T Cells: Deficiency of CMV-Specific CD8+ T Cells

Frontiers in Immunology, 2019
CMV colitis has been reported in immunocompromized patients with severe deficiency of CD4+ T cells and T cell functions. In this study we present an extensive immunological analysis in a patient with primary hypogammaglobulinemia and CMV colitis who had ...

CD80 Expressed by CD8+ T Cells Contributes to PD-L1-Induced Apoptosis of Activated CD8+ T Cells

Journal of Immunology Research, 2017
Tumor cells are capable of limiting antitumor CD8+ T cell responses through their cell surface expression of PD-L1. In addition to PD-1 expressed by CD8+ T cells, PD-L1 also binds to CD80 expressed by CD8+ T cells.

Interleukin-7 regulates CD127 expression and promotes CD8+ T cell activity in patients with primary cutaneous melanoma

BMC Immunology, 2022
Background Interleukin (IL)-7 signaling through CD127 is impaired in lymphocytes in cancers and chronic infections, resulting in CD8+ T cell exhaustion. The mechanisms underlying CD8+ T cell responses to IL-7 in melanoma remain not completely elucidated.

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.

Inflaming the CD8+ T Cell Response [PDF]

Immunity, 2006
Although inflammatory cytokines induced by infection or vaccination with adjuvants have long been known to stimulate optimal antigen-presenting cell function, recent evidence indicates that some inflammatory cytokines also act directly on the responding T cells to control their response to infection.

Avidity of influenza-specific memory CD8+ T-cell populations decays over time compromising antiviral immunity [PDF]

, 2012
Decline of cell-mediated immunity is often attributed to decaying T-cell numbers and their distribution in peripheral organs. This study examined the hypothesis that qualitative as well as quantitative changes contribute to the declining efficacy of CD8+

Defining Memory CD8 T Cell [PDF]

Frontiers in Immunology, 2018
CD8 T cells comprising the memory pool display considerable heterogeneity, with individual cells differing in phenotype and function. This review will focus on our current understanding of heterogeneity within the antigen-specific memory CD8 T cell compartment and classifications of memory CD8 T cell subsets with defined and discrete functionalities ...

Diversity in CD8+ T cell differentiation [PDF]

Current Opinion in Immunology, 2009
CD8(+) T cells are key effector cells of the adaptive immune system, however their activity must be tightly regulated to allow pathogen clearance whilst preventing immunopathology and autoimmunity. In this review, we summarise the diversity of responses that CD8(+) T cells make to antigenic stimulation with a focus on how CD8(+) T cell responses are ...

Dichotomous Roles of Programmed Cell Death 1 on HIV-Specific CXCR5+ and CXCR5− CD8+ T Cells during Chronic HIV Infection

Frontiers in Immunology, 2017
BackgroundCXCR5+CD8+ T cells have been demonstrated to play an important role in the control of chronic viral replication; however, the relationship between CXCR5+CD8+ T cells, HIV disease progression, and programmed cell death 1 (PD-1) expression ...

Phenotype and molecular signature of CD8+ T cell subsets in T cell- mediated rejections after kidney transplantation.

PLoS ONE, 2020
We investigated the phenotype and molecular signatures of CD8+ T cell subsets in kidney-transplant recipients (KTRs) with biopsy-proven T cell-mediated rejection (TCMR).
