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

open access: yesFrontiers 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.

CX3CR1 Modulates Migration of Resident Microglia Towards Cortical Laser‐Induced Lesions

open access: yesGlia, Volume 74, Issue 10, October 2026.
CX3CR1 deficiency promotes microglial migration toward CNS injury. Proteomic profiling reveals altered RHO‐mediated cytoskeletal signaling, while in vivo two‐photon imaging demonstrates increased process extension, velocity, and accumulation of Cx3cr1‐deficient microglia at lesion sites. ABSTRACT Microglia are innate immune cells of the central nervous

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

open access: yesProceedings 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 ...

ADP receptors P2Y1, P2Y12 and P2Y13 are differentially regulated in a rat model of multiple sclerosis

open access: yes, 2017
Introduction. Multiple sclerosis (MS) is a chronic disease of central nervous system (CNS), characterized by neuroinflammation, demyelination and neurodegeneration. Despite well-established role of purinergic signaling in MS pathology, the role of ADP as

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

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 20, Page 5999-6006, October 2026.
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 ...

Functional interaction between purinergic receptors: effect of ligands for A2Aand P2Y12receptors on P2Y1receptor function

open access: yesFEBS Letters, 2011
A(2A) adenosine receptor (A(2A)R), P2Y(1) receptor (P2Y(1)R) and P2Y(12) receptor (P2Y(12)R) are predominantly expressed on human platelets. The individual role of each of these receptors in platelet aggregation has been actively reported. Previously, hetero-oligomerization between these three receptors has been shown to occur. Here, we show that Ca(2+)

A trial of type 12 purinergic (P2Y12) receptor inhibition with prasugrel identifies a potentially distinct endotype of patients with aspirin-exacerbated respiratory disease [PDF]

open access: yesJournal of Allergy and Clinical Immunology, 2019
Aspirin-exacerbated respiratory disease (AERD) is characterized by asthma, recurrent nasal polyposis, and respiratory reactions on ingestion of COX-1 inhibitors. Increased numbers of platelet-leukocyte aggregates are present in the sinus tissue and blood of patients with AERD compared with that of aspirin-tolerant patients, and platelet activation can ...

Purinergic-Mediated Calcium Signaling in Quiescent and Activated Hepatic Stellate Cells: Evidence That P2Y1 Receptor Delays Activation

open access: yesCells
Hepatic stellate cells (HSC) play a crucial role in the fibrotic response of the liver when they transdifferentiate from quiescent cells (qHSC) to myofibroblast (MFB).

Microplastics‐Induced Gut Microbiota Dysbiosis Accelerates Alzheimer's‐Like Pathology and Cognitive Decline via the Gut–Brain Axis

open access: yesAdvanced Science, Volume 13, Issue 50, 7 September 2026.
Microplastics (MPs) breach the gut‐brain axis by triggering taurine‐depleting microbiota dysbiosis that accelerates Alzheimer‐like pathology in 5XFAD mice. Taurine supplementation normalizes autophagy, microglial quiescence, and cognition, and plasma taurine inversely tracks cognitive decline in ADNI participants, revealing a readily translatable ...

Microglia and neuroinflammation: An in‐depth analysis from functional diversity to disease mechanisms

open access: yesClinical and Translational Medicine, Volume 16, Issue 9, September 2026.
1. Microglial functions arise from dynamic, context‐dependent programs rather than fixed M1/M2 phenotypes. 2. Inflammatory, interferon‐responsive, phagocytic/lipid‐metabolic and repair‐associated programs coexist across disease stages and brain regions. 3.
