Hypoxia induces purinergic receptor signaling to disrupt endothelial barrier function

open access: yesFrontiers in Physiology, 2022
Blood-brain-barrier permeability is regulated by endothelial junctional proteins and is vital in limiting access to and from the blood to the CNS. When stressed, several cells, including endothelial cells, can release nucleotides like ATP and ADP that ...

Purinergic Signalling: Therapeutic Developments

open access: yesFrontiers in Pharmacology, 2017
Purinergic signalling, i.e., the role of nucleotides as extracellular signalling molecules, was proposed in 1972. However, this concept was not well accepted until the early 1990’s when receptor subtypes for purines and pyrimidines were cloned and ...

Impact of sleep insufficiency and recovery on cancer development

open access: yesSleep Research, EarlyView.
Abstract Sleep plays a critical role in overall health, and modern lifestyles, such as shift work and late‐night activities, can significantly impact sleep condition. Insufficient sleep has been associated with various adverse health outcomes, including an increased risk of tumor development.

Purinergic signaling: a common pathway for neural and mesenchymal stem cell maintenance and differentiation

open access: yesFrontiers in Cellular Neuroscience, 2015
Extracellular ATP, related nucleotides and adenosine are among the earliest signaling molecules, operating in virtually all tissues and cells. Through their specific receptors, namely purinergic P1 for nucleosides and P2 for nucleotides, they are ...

Adenosine—A Regulator of Human Testicular Peritubular Cells

open access: yesAndrology, EarlyView.
ABSTRACT Background Extracellular purines, in particular ATP and adenosine, are regulators of physiological and pathophysiological processes throughout the human body. Roles in the human testis are emerging and include actions on peritubular cells, which form the wall of seminiferous tubules.

Purine and purinergic receptors

open access: yesBrain and Neuroscience Advances, 2018
Adenosine 5′-triphosphate acts as an extracellular signalling molecule (purinergic signalling), as well as an intracellular energy source. Adenosine 5′-triphosphate receptors have been cloned and characterised. P1 receptors are selective for adenosine, a

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

open access: yesBritish 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

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

Purinergic Receptors in Ocular Inflammation

open access: yesMediators of Inflammation, 2014
Inflammation is a complex process that implies the interaction between cells and molecular mediators, which, when not properly “tuned,” can lead to disease.

Purinergic Signaling in Controlling Macrophage and T Cell Functions During Atherosclerosis Development

open access: yesFrontiers in Immunology, 2021
Atherosclerosis is a hardening and narrowing of arteries causing a reduction of blood flow. It is a leading cause of death in industrialized countries as it causes heart attacks, strokes, and peripheral vascular disease.
