Intraepithelial CD8-positive T lymphocytes predict survival for patients with serous stage III ovarian carcinomas: relevance of clonal selection of T lymphocytes [PDF]

British Journal of Cancer, 2009
The aim of this study was to investigate the prognostic effect of tumour-infiltrating lymphocytes (TILs) in serous stage III ovarian carcinoma to determine TIL clonality and to correlate this to Her2/neu expression.Formalin-fixed and paraffin-embedded ovarian carcinomas were examined for CD20-, CD3-, CD4- and CD8-positive lymphocytes (n=100), and for ...

CD8-positive T lymphocytes specific for murine cytomegalovirus immediate-early antigens mediate protective immunity [PDF]

Journal of Virology, 1987
We have shown in a murine model system for acute, lethal cytomegalovirus (CMV) disease in the immunocompromised natural host that control of virus multiplication in tissues, protection from virus-caused tissue destruction, and survival are mediated by virus-specific CD8+ CD4-T lymphocytes.

Erythrodermic CD4/CD8 Double-Negative Mycosis Fungoides: A Case Report

Case Reports in Oncology, 2021
Cutaneous T-cell lymphoma (CTCL) describes a group of lymphoproliferative disorders characterized by localization of neoplastic T lymphocytes to the skin. Mycosis fungoides (MF) represents the most common type of CTCL and accounts for ∼60% of all primary

Prolonged enhancement of cytotoxic T lymphocytes in the post-recovery state of severe COVID-19

Journal of Intensive Care, 2021
We evaluated the peripheral blood immune responses of lymphocytes in severe Coronavirus disease 2019 (COVID-19) patients in different stages of recovery using single-cell mass cytometry.

T lymphocytes infiltrating advanced grades of cervical neoplasia. CD8-positive cells are recruited to invasion [PDF]

Cancer, 1995
Impaired cellular immunity appears to be a risk factor for progression of cervical neoplasia, but the immunobiology of neoplastic progression is poorly understood. The objective of this study was to characterize the subpopulations of T lymphocytes that infiltrate various grades of cervical neoplasia including metaplasia to invasive cancer in ...

USE OF TCR Vβ2 REPERTOIRES TO DIFFERENTIATE CD8 T-CELL LYMPHOMAS FROM INFECTIOUS DISEASE REACTIVE LYMPHOCYTOSIS

Hematology, Transfusion and Cell Therapy, 2021
Introduction: Reactive lymphocytosis can be difficult to differentiate from clonal lymphocytosis, especially when it involves CD8 positive T-lymphocytes. Leukemias and lymphomas cause an increase in this population at the expense of replication of clonal

Inflammatory and immune checkpoint markers are associated with the severity of aortic stenosisCentral MessagePerspective

JTCVS Open, 2021
Objective: Aortic stenosis (AS) is a disease characterized by narrowing of the aortic valve (AV) orifice. In relation to this disease, the purpose of this study was to elucidate the relationships among factors such as expression of programmed cell death ...

A murine intestinal intraepithelial NKp46-negative innate lymphoid cell population characterized by group 1 properties [PDF]

, 2017
The Ly49E receptor is preferentially expressed on murine innate-like lymphocytes, such as epidermal V gamma 3 T cells, intestinal intraepithelial CD8 alpha alpha(+) T lymphocytes, and CD49a(+) liver natural killer (NK) cells.

Negative and positive selection of antigen-specific cytotoxic T lymphocytes affected by the α3 domain of MHC I molecules [PDF]

, 1991
THE α1 and α2 domains of major histocompatibility complex (MHC) class I molecules function in the binding and presentation of foreign peptides to the T-cell antigen receptor and control both negative and positive selection of the T-cell repertoire ...
