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 in scarring

The FASEB Journal, 2015
ABSTRACT Adenosine (ADO) and nucleotides such as ATP, ADP, and uridine 5'‐triphosphate (UTP), among others, may serve as extracellular signaling molecules. These mediators activate specific cell‐surface receptors—namely, purinergic 1 and 2 (P1 and P2)—to modulate crucial pathophysiological responses. Regulation of

Purinergic signaling in kidney disease [PDF]

Kidney International, 2017
Nucleotides are key subunits for nucleic acids and provide energy for intracellular metabolism. They can also be released from cells to act physiologically as extracellular messengers or pathologically as danger signals. Extracellular nucleotides stimulate membrane receptors in the P2 and P1 family. P2X are ATP-activated cation channels; P2Y and P1 are

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.

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 ...

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 ...

A 3D Astrocyte Microenvironment Model Enables Rapid Ca2+‐Resolved Analysis and Therapeutic Modulation of Oxidative Neuroinflammation

Advanced Healthcare Materials, EarlyView.
This work presents ARC‐3D, a soft 3D model that recreates how brain support cells, called astrocytes, react to oxidative stress. The system visualizes rapid calcium changes and inflammatory signals, and shows how the drug KDS12025 can protect cells from damage. ARC‐3D offers a simple, reliable way to study early drivers of brain inflammation.

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 ...

ENTPDase inhibitors: therapeutic potential in infectious, inflammatory, and neuroinflammatory diseases [PDF]

Exploration of Neuroscience
Ectonucleoside triphosphate diphosphohydrolases (ENTPDases), members of the cluster of differentiation 39 (CD39) family, are key regulators of purinergic signaling through the hydrolysis of tri and diphosphate nucleotides.

De Novo Gene Transcription of Connexin Mediates Cytoplasmic Fluid Exchange and Flocking Transitions in Physiological and Cancerous Epithelial Systems

Advanced Science, EarlyView.
EGF‐induced de novo transcription of connexins Cx26 and Cx31 promotes flocking behavior that fluidizes epithelia and enables coordinated collective migration. Connexin‐driven cytoplasmic exchange mechanistically links growth‐factor signaling to invasive dynamics.
