Resetting intrinsic purinergic modulation of neural activity: an associative mechanism? [PDF]

open access: yes, 2002
The purines, ATP and adenosine, control the rundown and termination of swimming in the Xenopus embryo. This intrinsic purinergic modulation, unavoidably present during every swimming episode, could lead to stereotyped inflexible behavior and consequently

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

Ontogeny of purinergic receptor-regulated Ca2+ signaling in mouse cortical collecting duct epithelium [PDF]

open access: yes, 2002
Changes in ATP-induced increase in {[}Ca2+], during collecting duct ontogeny were studied in primary monolayer cultures of mouse ureteric bud (UB) and cortical collecting duct (CCD) cells by Fura-PE3 fluorescence ratio imaging.

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

The developmental journey of therapies targeting purine receptors: from basic science to clinical trials

open access: yes, 2022
Since the discovery of ATP as an extracellular signalling molecule in 1972, purinergic signalling, mediated by extracellular purines and pyrimidines has been identified in virtually all mammalian tissues and is implicated in regulating fundamental ...

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.

Quantifying Heteromer Partitioning Reveals Inflammation‐Dependent Redistribution of Microglial Adenosine A2A and Cannabinoid CB2 Receptors

open access: yesGlia, Volume 74, Issue 9, September 2026.
Proinflammatory activation reorganizes microglial A2A and CB2 receptors, promoting their incorporation into stable heteromers and blocking agonist‐induced redistribution. The results reveal those heteromers as potential therapeutic targets in inflammatory contexts.

Role of adenosine A2a receptor in cancers and autoimmune diseases

open access: yesImmunity, Inflammation and Disease, 2023
Adenosine receptors are P1 class of purinergic receptors that belong to G protein‐coupled receptors. There are 4 subtypes of adenosine receptors, namely A1, A2A, A2B, and A3. A2AR has a high affinity for the ligand adenosine.
