Consequences of the Lack of CD73 and Prostatic Acid Phosphatase in the Lymphoid Organs

Mediators of Inflammation, 2014
CD73, ecto-5′-nucleotidase, is the key enzyme catalyzing the conversion of extracellular AMP to adenosine that controls vascular permeability and immunosuppression.

Features of the oxidation processes and state of microcirculatory channel have persons exposed to low doses of ionizing radiation

Бюллетень сибирской медицины, 2012
We have examined 36 liquidators (participants in emergency clean-up after the Chernobylnuclear accident) many years after the external γ-irradiation (on average (143.0 ± 14.0) mGy for (3.3 ± 0.8) months) and 13 workers of a typical research nuclear ...

Salivary Extracellular Vesicles: Paradigm Shift in Liquid Biopsy Diagnostics

Journal of Extracellular Biology, Volume 5, Issue 7, July 2026.
ABSTRACT Extracellular vesicles (EVs), lipid bilayer nanoparticles released by virtually all cells, serve as essential messengers for intercellular communication. Due to their involvement in several pathophysiological processes, EVs have recently gained considerable attention as potentially diagnostic and prognostic biomarkers for various illnesses ...

Analysis of the NTPDase and ecto-5'-nucleotidase profiles in serum-limited Trichomonas vaginalis

Memorias do Instituto Oswaldo Cruz, 2012
Trichomonas vaginalis is a parasite of the human urogenital tract that causes trichomonosis, the most prevalent non-viral sexually transmitted disease. Ectonucleoside triphosphate diphosphohydrolase (NTPDase) family members, which hydrolyse extracellular

A Novel Polyphosphate‐Degrading Enzyme Confers Growth on Exogenous Polyphosphate in the Archaeon Haloferax volcanii

Environmental Microbiology, Volume 28, Issue 7, July 2026.
A novel polyP‐degrading enzyme with an activity differing from those currently known was found in Haloferax volcanii, conferring the ability for this microbe to grow on extracellular polyP. These findings further our understanding of the potential ecological roles of polyP and how archaea metabolise this essential biopolymer.

Electrophoretic fractionation of 5'-nucleotidase

Clinical Chemistry, 1994
Abstract Human isonucleotidases were separated by electrophoresis on a cellulose acetate membrane. Three 5'-nucleotidase forms, NTP1, NTP2, and NTP3, were resolved with this method and quantified by densitometry. The procedure was not only simple and rapid but also sufficiently precise (between-run CV < 20%) and sensitive ...

Immune‐Driven Expression in Inclusion Body Myositis With T‐Cell Large Granular Lymphocytic Leukemia

Annals of Clinical and Translational Neurology, Volume 13, Issue 6, Page 1196-1205, June 2026.
ABSTRACT Objectives T‐cell large granular lymphocytic leukemia (T‐LGLL), reported in up to 58% of inclusion body myositis (IBM) patients, is a rare leukemia of cytotoxic or less commonly helper T cells. The range of myopathies in T‐LGLL and the impact of coexisting T‐LGLL in IBM are not well understood. Our objectives are to investigate the spectrum of

Feed-Forward Inhibition of CD73 and Upregulation of Adenosine Deaminase Contribute to the Loss of Adenosine Neuromodulation in Postinflammatory Ileitis

Mediators of Inflammation, 2014
Purinergic signalling is remarkably plastic during gastrointestinal inflammation. Thus, selective drugs targeting the “purinome” may be helpful for inflammatory gastrointestinal diseases. The myenteric neuromuscular transmission of healthy individuals is

Chemotherapy Effects on the Activities of Some Purine Metabolic Enzymes in Sera of Ovarian Cancer Patients

مجلة بغداد للعلوم, 2010
Adenosine deaminase (ADA; Ec: 3.5.4.4), 5´- Nucleotidase (5´– NT; Ec: 3.1.3.5), and AMP – amino hydrolase (AMP – deaminase AMPDA; Ec: 3.5.4.6) activities were measured in sera of ovarian cancer patients before surgery, and after chemotherapy.

The 5'-nucleotidase S5nA is dispensable for evasion of phagocytosis and biofilm formation in Streptococcus pyogenes.

PLoS ONE, 2019
5'-nucleotidases are widespread among all domains of life. The enzymes hydrolyze phosphate residues from nucleotides and nucleotide derivatives. In some pathobiontic bacteria, 5'-nucleotidases contribute to immune evasion by dephosphorylating adenosine ...
