CD38+CD39+ NK cells associate with HIV disease progression and negatively regulate T cell proliferation

Frontiers in Immunology, 2022
The ectonucleotidases CD38 and CD39 have a critical regulatory effect on tumors and viral infections via the adenosine axis. Natural killer (NK) cells produce cytokines, induce cytotoxic responses against viral infection, and acquire immunoregulatory ...

Autoreactivity Versus Autoimmunity: Characteristics of Autoantigen‐Specific CD4 T Cells in Rheumatoid Arthritis and Health

Arthritis &Rheumatology, EarlyView.
Objective CD4 T cells specific for citrullinated (cit) peptides are key players in rheumatoid arthritis (RA) immunopathogenesis. Characterizing these cells and identifying features of healthy and RA‐associated autoreactivity will provide valuable insight into disease mechanisms and form the basis of immune state biomarkers to facilitate the next ...

Rat pancreas secretes particulate ecto-nucleotidase CD39

, 2003
Udgivelsesdato: 2003-Sep-15In exocrine pancreas, acini release ATP and the excurrent ducts express several types of purinergic P2 receptors. Thereby, ATP, or its hydrolytic products, might play a role as a paracrine regulator between acini and ducts. The

Potential effect of tumor-specific Treg-targeted antibodies in the treatment of human cancers: A bioinformatics analysis

OncoImmunology, 2018
One of the mechanisms of tumor rejection in immune-modulatory treatments is antibody-dependent cell-mediated cytotoxicity (ADCC) of regulatory T cells (Tregs) that infiltrate tumors in which cells expressing activating Fcγ receptors (FcγRs) are present ...

PURINERGIC REGULATION OF BASIC PHYSIOLOGICAL AND PATHOLOGICAL PROCESSES

Медицинская иммунология, 2018
Purinergic signaling has been actively studied over recent years. It happens, due to its involvement in pathogenesis of various diseases and pathologies such as infectious and non-infectious inflammation, tumor growth, graft-versus-host disease ...

Persistent Interleukin‐18 Fuels Expansion of CD38+HLA‐DR+CD8+ T Cells in Still Disease and Macrophage Activation Syndrome

Arthritis &Rheumatology, EarlyView.
Objective Still disease (SD) is an autoinflammatory disorder characterized by remarkably high interleukin‐18 (IL‐18) levels. Increasing evidence suggests that adaptive immunity also contributes to its pathogenesis, particularly in refractory courses. Macrophage activation syndrome (MAS), one of SD's most severe complications, is associated with further

In vitro Study of a Novel Stent Coating Using Modified CD39 Messenger RNA to Potentially Reduce Stent Angioplasty-Associated Complications. [PDF]

PLoS ONE, 2015
Stent angioplasty provides a minimally invasive treatment for atherosclerotic vessels. However, no treatment option for atherosclerosis-associated endothelial dysfunction, which is accompanied by a loss of CD39, is available, and hence, adverse effects ...

Monocyte inflammation and adaptive immune dysfunction in severe Klebsiella pneumoniae pneumonia

iMeta, EarlyView.
Severe Klebsiella pneumoniae pneumonia combines intense inflammation with failure to control infection, yet the cellular basis is unclear. Using a severity‐focused single‐cell atlas of 708,894 peripheral blood mononuclear cells from 100 individuals, complemented by plasma protein measurements and flow cytometry, we show that disease severity redirects ...

Expression of CD39 Is Correlated With HIV DNA Levels in Naïve Tregs in Chronically Infected ART Naïve Patients

Frontiers in Immunology, 2019
Background: Treg cells represent important viral reservoirs during chronic HIV infection. CD39 is closely involved in Treg-mediated immunosuppressive effects. However, CD39 expression on nTregs and mTregs and a relationship with HIV DNA levels during HIV
