Age-related decrease of miRNA-92a levels in human CD8⁺ T-cells correlates with a reduction of naïve T lymphocytes

Immunity & Ageing, 2011
MicroRNA (miR)-17-92a expression plays a crucial role in lymphocyte ontogeny. We therefore set out to determine miR-92a expression levels in peripheral blood lymphocytes from healthy subjects to ascertain any association between these levels and ageing ...

CD3+CD4+CD8+ T-LYMPHOCYTES COUNT IN PROGNOSIS OF EARLY KIDNEY ALLOGRAFT DYSFUNCTION

Žurnal Grodnenskogo Gosudarstvennogo Medicinskogo Universiteta, 2020
Background. Double-positive CD3+CD4+CD8+ T-lymphocytes are significant in the immune response to various infectious agents. Pancreatic islet transplantation in the experiment characterizes CD3+CD4+CD8+ as a new biomarker for donor cells rejection ...

Characterizing the immune microenvironment of malignant peripheral nerve sheath tumor by PD-L1 expression and presence of CD8+ tumor infiltrating lymphocytes. [PDF]

, 2016
BackgroundMalignant peripheral nerve sheath tumor (MPNST) is an aggressive sarcoma with few treatment options. Tumor immune state has not been characterized in MPNST, and is important in determining response to immune checkpoint blockade.

Olink Proteomics Analysis Reveals Heterogeneous Responses to FcRn Blockade in Anti‐AChR Antibody‐Positive Myasthenia Gravis: FGF‐19 as a Novel Biomarker

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective This study aimed to systematically observe the clinical manifestations, immune cell subsets, and dynamic changes in serological indicators in patients with myasthenia gravis (MG) before and after efgartigimod (EFG) treatment. Methods We analyzed the baseline data, laboratory parameters, and lymphocyte subset proportions in MG ...

Cytotoxic T lymphocytes in regional lymph nodes in colon cancer

Acta Biomedica Scientifica
Background. The study of the subpopulation composition of cytotoxic T lymphocytes and the expression of co-inhibitory proteins on their surface in regional lymph nodes is necessary for the development of new methods of targeted therapy for colorectal ...

Predominance of weakly cytotoxic, T-betLowEomesNeg CD8+ T-cells in human gastrointestinal mucosa: implications for HIV infection. [PDF]

, 2017
The gastrointestinal mucosa is an important site of HIV acquisition, viral replication, and pathogenesis. Immune cells in mucosal tissues frequently differ in phenotype and function from their non-mucosal counterparts.

In‐Depth Profiling Highlights the Effect of Efgartigimod on Peripheral Innate and Adaptive Immune Cells in Myasthenia Gravis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Myasthenia gravis (MG) is an autoimmune disorder characterized by antibody‐mediated complement activation. Efgartigimod, a neonatal Fc receptor (FcRn) antagonist, is approved for treating generalized MG (gMG). However, its modulatory effects on upstream innate and adaptive immune cells remain largely unexplored.

Effector cell mediated cytotoxicity measured by intracellular Granzyme B release in HIV infected subjects

Biological Procedures Online, 2003
CD8+ cytotoxic T lymphocyte (CTL) activity is currently believed to be one of the key immunologic mechanisms responsible for the prevention or attenuation of HIV-1 infection.

Shared Genetic Effects and Antagonistic Pleiotropy Between Multiple Sclerosis and Common Cancers

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Epidemiologic studies have reported inconsistent altered cancer risk in individuals with multiple sclerosis (MS). Factors such as immune dysregulation, comorbidities, and disease‐modifying therapies may contribute to this variability.
