Hyperacute Interleukin‐1β Production and Neutrophil Extracellular Trap Formation in the Cerebral Circulation of Stroke Patients with Large Vessel Occlusion

Annals of Neurology, EarlyView.
Acute ischemic stroke due to large vessel occlusion is associated with rapid intravascular immune activation. Analysis of arterial blood sampled distal to the thrombus during mechanical thrombectomy revealed increased extracellular adenosine triphosphate (ATP) and interleukin‐1β (IL‐1β) levels, evidence of inflammasome priming in monocytes, and ...

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

Diabetes‐Induced Dysregulation of Purinergic Signaling in the Bladder Mucosa: Accelerated ATP Hydrolysis and Impaired Adenosine Uptake Promote Underactive Bladder Phenotype

Neurourology and Urodynamics, EarlyView.
ABSTRACT Objective To explore molecular mechanisms underlying excessive extracellular adenosine (ADO) accumulation in the bladder lamina propria (LP) of mice with type 2 diabetes (T2D) induced by a high‐fat, high‐sucrose diet (HFHSD), conceivably leading to bladder underactivity.

Difference in NaCl tolerance of membrane-bound 5′-nucleotidases purified from deep-sea and brackish water Shewanella species [PDF]

, 2017
Shewanella species are widely distributed in sea, brackish, and fresh water areas, growing psychrophilically or mesophilically, and piezophilically or piezo-sensitively. Here, membrane-bound 5′-nucleotidases (NTases) from deep-sea Shewanella violacea and

Targeting Immunometabolism Mediated by CD73 Pathway in EGFR-Mutated Non-small Cell Lung Cancer: A New Hope for Overcoming Immune Resistance

Frontiers in Immunology, 2020
Despite the relevant antitumor efficacy of immunotherapy in advanced non-small cell lung cancer (NSCLC), the results in patients whose cancer harbors activating epidermal growth factor receptor (EGFR) mutations are disappointing.
