Frequency over function : raised levels of CD127low/- regulatory T cells in the tumour microenvironment compared with the periphery of head and neck cancer patients [PDF]

, 2014
Objective: Regulatory T cells (Tregs) are known to infiltrate the tumour microenvironment of many cancers, including head and neck malignancies, and are thought to contribute to the host's impaired anti-tumour immune response.

CD4+CD25+ regulatory T lymphocytes in tuberculous pleural effusion

Chinese Medical Journal, 2008
Active suppression by CD4+CD25+ regulatory T lymphocytes plays an important role in the down-regulation of T cell responses to foreign and self-antigens. This study was conducted to analyze whether the CD4+CD25+ regulatory T cells exist and function normally in tuberculous pleural effusion.The percentages of CD4+CD25+ T cells in pleural effusion and ...

Regulatory T-Cells Suppress Cytotoxic T Lymphocyte Responses against Microglia

Cells, 2022
Regulatory T-cells (Tregs) play pivotal roles during infection, cancer, and autoimmunity. In our previous study, we demonstrated a role for the PD-1:PD-L1 pathway in controlling cytolytic responses of CD8+ T lymphocytes against microglial cells presenting viral peptides.

E2A selectively regulates TGF‐β–induced apoptosis in KRAS‐mutant non‐small cell lung cancer

Molecular Oncology, EarlyView.
Ability to induce apoptosis by TGF‐β is frequently lost in advanced lung adenocarcinoma despite intact TGF‐β signaling. We identify E2A as a mutant KRAS–dependent mediator of resistance to TGF‐β–induced apoptosis. TGF‐β induces E2A via SMAD3 in mutant KRAS cells, and E2A silencing restores apoptosis and enhances radiation response in cell lines ...

Investigating age-related dynamics and transcriptional signatures of CD8⁺HLA-DR⁺ regulatory T lymphocytes: perspectives in understanding immune system aging

Медицинская иммунология
The ability of the CD8+HLA-DR+ regulatory T lymphocytes population to regulate the immune response was first described several years ago. It is known that the suppressive effects of these cells depend on intercellular interactions and are mediated by the

Apolipoprotein E-containing HDL decreases caspase-dependent apoptosis of memory regulatory T lymphocytes

Journal of Lipid Research, 2023
Plasma levels of HDL cholesterol are inversely associated with CVD progression. It is becoming increasingly clear that HDL plays important roles in immunity that go beyond its traditionally understood roles in lipid transport. We previously reported that

Immunological backbone of uveal melanoma: is there a rationale for immunotherapy? [PDF]

, 2019
No standard treatment has been established for metastatic uveal melanoma (mUM). Immunotherapy is commonly used for this disease even though UM has not been included in phase III clinical trials with checkpoint inhibitors.

Cell‐cycle‐specific lesion evolution rather than inhibition of double‐strand‐break repair underpins cisplatin radiosensitization

Molecular Oncology, EarlyView.
We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...

IL-24 producing regulatory T and B lymphocytes in endometriosis

Frontiers in Immunology
ProblemUnbalanced production of pro- and anti-inflammatory cytokines by immune cells is a hallmark of endometriosis. IL-24, a member of the IL-10 family, is a pleiotropic cytokine produced by both non-immune cells like astrocytes, keratinocytes ...

Recombinant human PDCD5 (rhPDCD5) protein is protective in a mouse model of multiple sclerosis. [PDF]

, 2015
BackgroundIn multiple sclerosis (MS) and its widely used animal model, experimental autoimmune encephalomyelitis (EAE), autoreactive T cells contribute importantly to central nervous system (CNS) tissue damage and disease progression. Promoting apoptosis
