Generation and characterization of antagonistic anti-human CD39 nanobodies

Frontiers in Immunology
CD39 is the major enzyme controlling the levels of extracellular adenosine triphosphate (ATP) via the stepwise hydrolysis of ATP to adenosine diphosphate (ADP) and adenosine monophosphate (AMP).

High-dimensional analysis of the adenosine pathway in high-grade serous ovarian cancer

Journal for ImmunoTherapy of Cancer, 2021
Background Hydrolysis of extracellular ATP to adenosine (eADO) is an important immune checkpoint in cancer immunology. We here investigated the impact of the eADO pathway in high-grade serous ovarian cancer (HGSC) using multiparametric platforms.Methods ...

Inosine‐Triphosphate‐Pyrophosphatase Activity as a Potential Predictor of Methotrexate Remission in Juvenile Idiopathic Arthritis

Arthritis &Rheumatology, EarlyView.
Objective Methotrexate (MTX) is the first‐line therapy for juvenile idiopathic arthritis (JIA), but up to 40% of patients do not respond to it. Low inosine triphosphate pyrophosphatase (ITPA) activity has been associated with reduced clinical remission. We investigated the role and underlying mechanisms of ITPA in vitro. Methods ITPA enzymatic activity

Features of parameters of cellular immune depending on the activity of foci of demyelination in children with multiple sclerosis

Медицинская иммунология, 2023
MS is a common disease of the central nervous system that leads to disability and reduced quality of life. The debut of disease in 3-5% of patients occurs in childhood and has a less favorable course compared to adults.

Interleukin‐2 Deprived State of Regulatory T cells and Their Recovery by Low‐Dose Interleukin‐2 in Patients With Inflammatory Myopathies

Arthritis &Rheumatology, EarlyView.
Objective Regeneration and expansion of Treg by low‐dose interleukin‐2 (IL‐2) therapy is considered a potential treatment strategy for a wide range of autoimmune diseases. To provide a pathophysiologically‐based rationale for low‐dose IL‐2 therapy, we investigated whether reversible defects in the Treg–IL‐2 axis emerge in inflammatory myopathies ...

Rat pancreas secretes particulate ecto-nucleotidase CD39

The Journal of Physiology, 2003
In 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 aim of the present study was to elucidate whether this acinar-ductal signalling is regulated by nucleotidase(s), and to ...

Ecto-nucleotidases activities in the contents of ovarian endometriomas: potential biomarkers of endometriosis [PDF]

, 2015
Endometriosis, defined as the growth of endometrial tissue outside the uterus, is a common gynecologic condition affecting millions of women worldwide. It is an inflammatory, estrogen-dependent complex disorder, with broad symptomatic variability, pelvic

5‐Methylcytosine Analysis of miRNAs in Minimal Change Disease

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Minimal change disease (MCD) is a glomerular disorder, which is the most common cause of nephrotic syndrome in children. Additionally, the prevalence of MCD in adults has been increasing in recent years. During protein synthesis, noncoding RNAs can be regulated through a variety of modifications, which helps preserve biological diversity and ...

Identification and Characterization of CD39/Vascular ATP Diphosphohydrolase [PDF]

Journal of Biological Chemistry, 1996
Vascular ATP diphosphohydrolase (ATPDase) is a plasma membrane-bound enzyme that hydrolyses extracellular ATP and ADP to AMP. Analysis of amino acid sequences available from various mammalian and avian ATPDases revealed their close homology with CD39, a putative B-cell activation marker.

Altered CD39 and CD73 Expression in Rheumatoid Arthritis: Implications for Disease Activity and Treatment Response

Biomolecules, 2023
In rheumatoid arthritis (RA) synovium, ATP, and ADP are released, sparking inflammation. Ectoenzymes CD39 and CD73 metabolize these purine nucleotides, generating anti-inflammatory adenosine. Therefore, dysregulated CD39 and CD73 expression may impact RA
