The cellular distribution of P2X7, P2Y6, and P2Y12 during or after pilocarpine-induced status epilepticus and literature review

Brain Circulation
BACKGROUND: When a seizure occurs, the distribution of purine receptors in different cell types at various time points remains poorly understood. Our literature review revealed that P2X7, P2Y6, and P2Y12 are expressed in different cells during epilepsy ...

Gene‐by‐environment effect of house dust mite on purinergic receptor P2Y12 (P2RY12) and lung function in children with asthma [PDF]

Clinical & Experimental Allergy, 2011
SummaryBackgroundDistinct receptors likely exist for leukotriene (LT)E4, a potent mediator of airway inflammation. Purinergic receptor P2Y12 is needed for LTE4‐induced airways inflammation, and P2Y12 antagonism attenuates house dust mite‐induced pulmonary eosinophilia in mice.

VlPAG/DRN Microglia Drive Neuropathic Pain‐Induced Depression via a Defined Neuroimmune Axis

Advanced Science, EarlyView.
Peripheral nerve injury (SNI) induces neuropathic pain, activates midbrain microglia, and triggers an NLRP3–IL‐1β–dependent inflammatory cascade. IL‐1β signals through IL‐1R1 on vlPAG/DRN VGLUT2+ neurons (vlPAG/DRNGlu), inducing hyperexcitability and driving the vlPAG/DRNGlu→BNSTGABA circuit to produce the affective component of neuropathic pain ...

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.

Current status and future perspectives of platelet function‐guided precision antiplatelet therapy for patients with cerebral infarction

Neuroprotection, EarlyView.
Antiplatelet agents target the cyclooxygenase‐1 (COX‐1)/thromboxane A2 (TXA2) and adenosine diphosphate (ADP)‐P2Y12 (cytochrome P450 2C19 [CYP2C19]‐metabolized) platelet activation pathways, resulting in either drug resistance or over‐inhibition. The individualized therapeutic window balances ischemic risk (triggered by high on‐treatment platelet ...

Human brain matters: Navigating the neuropathology of COVID‐19

Brain Pathology, EarlyView.
Severe COVID‐19 is associated with vascular dysregulation and chronic neuroinflammation, leading to axonal injury and neurodegeneration. In long COVID or PASC, persistent alterations in neuroimaging and biofluid biomarkers reflect ongoing neuronal damage and neuroinflammation, contributing to long‐term neurological symptoms including fatigue, cognitive

Mechanosensory Signaling in Enterochromaffin Cells and 5-HT Release: Potential Implications for Gut Inflammation

Frontiers in Neuroscience, 2016
Enterochromaffin cells (EC) synthesize 95% of the body 5-HT and release 5-HT in response to mechanical or chemical stimulation. EC cell 5-HT has physiological effects on gut motility, secretion and visceral sensation.

Blockade of the purinergic P2Y ₁₂ receptor greatly increases the platelet inhibitory actions of nitric oxide [PDF]

Proceedings of the National Academy of Sciences, 2013
Circulating platelets are constantly exposed to nitric oxide (NO) released from the vascular endothelium. This NO acts to reduce platelet reactivity, and in so doing blunts platelet aggregation and thrombus formation. For successful hemostasis, platelet activation and aggregation must occur at sites of vascular injury despite the ...

The potential for biased signalling in the P2Y receptor family of GPCRs

British Journal of Pharmacology, EarlyView.
The purinergic receptor family is primarily activated by nucleotides, and contains members of both the G protein coupled‐receptor (GPCR) superfamily (P1 and P2Y) and ligand‐gated ion channels (P2X). The P2Y receptors are widely expressed in the human body, and given the ubiquitous nature of nucleotides, purinergic signalling is involved with a plethora

The lung is more than an organ of gas exchange: immunocompetency, platelets and implications for drug discovery

British Journal of Pharmacology, EarlyView.
Abstract The lungs have for a long time been recognised as having pharmacological significance as a specific organ to modulate the pharmacokinetics of endogenous substances needed to maintain homeostasis. The lungs are therefore the site of action of certain drugs that act on these homeostatic processes, resulting in systemic effects on the ...
