Neonatal Seizures and Purinergic Signalling [PDF]

International Journal of Molecular Sciences, 2020
Neonatal seizures are one of the most common comorbidities of neonatal encephalopathy, with seizures aggravating acute injury and clinical outcomes. Current treatment can control early life seizures; however, a high level of pharmacoresistance remains among infants, with increasing evidence suggesting current anti-seizure medication potentiating brain ...

Purinergic Regulation of Neutrophil Function

Frontiers in Immunology, 2018
Purinergic signaling, which utilizes nucleotides (particularly ATP) and adenosine as transmitter molecules, plays an essential role in immune system. In the extracellular compartment, ATP predominantly functions as a pro-inflammatory molecule through ...

Integrating UHPLC-MS/MS quantitative analysis and exogenous purine supplementation to elucidate the antidepressant mechanism of Chaigui granules by regulating purine metabolism

Journal of Pharmaceutical Analysis, 2023
Chaigui granules (CG) are a compound composed of six herbal medicines with significant antidepressant effects. However, the antidepressant mechanism of CG remains unclear. In the present study, we attempted to elucidate the antidepressant mechanism of CG

Purinergic Signaling During Hyperglycemia in Vascular Smooth Muscle Cells

Frontiers in Endocrinology, 2020
The activation of purinergic receptors by nucleotides and/or nucleosides plays an important role in the control of vascular function, including modulation of vascular smooth muscle excitability, and vascular reactivity.

Dysregulation of Astrocytic ATP/Adenosine Release in the Hippocampus Cause Cognitive and Affective Disorders: Molecular Mechanisms, Diagnosis, and Therapy

MedComm
The gliotransmitter adenosine 5'‐triphosphate (ATP) and its enzymatic degradation product adenosine play a major role in orchestrating in the hippocampus cognitive and affective functions via P2 purinoceptors (P2X, P2Y) and P1 adenosine receptors (A1 ...

Purinergic signalling in neuroregeneration

Neural Regeneration Research, 2015
Purinergic signalling, adenosine 5′-triphosphate (ATP) as an extracellular signalling molecule, was proposed in 1972 (Burnstock, 1972). However, it was not generally accepted until the early 1990s when receptors for ATP and its breakdown product adenosine were cloned and characterised (Ralevic and Burnstock, 1998).

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death

FEBS Open Bio, EarlyView.
Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...

Cardiomyocytes HIPK2 regulates myocardial inflammation and heart function through purinergic signaling

Cell Communication and Signaling
Purinergic signaling is critical to myocardial inflammation and function. However, the underlying mechanisms are not well defined. Herein, we identified a protein kinase, homeodomain-interacting protein kinase 2 (HIPK2), as a novel regulator of ...

Purinergic signalling in osteoblasts

Frontiers in Bioscience, 2012
The skeleton is maintained throughout life via the finely tuned actions of osteoblasts and osteoclasts, with disruption in this balance eventually leading to bone disease. The exact mechanisms balancing these actions are not fully known, although several regulatory systems are known to be involved.

Baseline Neuroinflammation Stratifies TSPO‐PET Response to Disease‐Modifying Therapy in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To investigate which baseline clinical and imaging characteristics best predict TSPO‐PET‐measurable reduction in glial activation following treatment of multiple sclerosis (MS), to utilize this information for designing more efficient biomarker‐based clinical trials targeting glial activation.
