Purines, Purinergic Receptors, and Cancer [PDF]

open access: yesCancer Research, 2012
AbstractPurines were long thought to be restricted to the intracellular compartment, where they are used for energy transactions, nucleic acid synthesis, and a multiplicity of biochemical reactions. However, it is now clear that both adenosine and adenosine triphosphate are (i) abundant biochemical components of the tumor microenvironment, (ii) potent ...

Changes in P2Y Purinergic Receptor Expression in the Ciliary Body in a Murine Model of Glaucoma

open access: yesFrontiers in Pharmacology, 2017
Glaucoma is a neuropathology, often accompanied by an elevated intraocular pressure (IOP), which can lead to blindness. Since DBA/2J mice develop glaucoma, several studies of the physiopathology of glaucoma have been reported in this animal model.

Purinergic and Adenosinergic Signaling in Pancreatobiliary Diseases

open access: yesFrontiers in Physiology, 2022
Adenosine 5'-triphosphate (ATP), other nucleotides, and the nucleoside analogue, adenosine, all have the capacity to modulate cellular signaling pathways.

Purinergic Signaling in Neuroinflammation

open access: yes, 2023
It is currently apparent that extracellular ATP's physiological effect is mediated by its interaction with specific purinergic receptors. All purinergic receptors are divided into P1-purinoreceptors and P2-purinoreceptors. Each of the subtypes is divided

Purinergic receptors in cognitive disturbances

open access: yesNeurobiology of Disease, 2023
Purinergic receptors (Rs) of the ATP/ADP, UTP/UDP (P2X, P2Y) and adenosine (A1, A2A)-sensitive classes broadly interfere with cognitive processes both under quasi normal and disease conditions. During neurodegenerative illnesses, high concentrations of ATP are released from the damaged neuronal and non-neuronal cells of the brain; then, this ATP is ...

Pharmacochemistry of the platelet purinergic receptors [PDF]

open access: yesPurinergic Signalling, 2011
Platelets contain at least five purinergic G protein-coupled receptors, e.g., the pro-aggregatory P2Y(1) and P2Y(12) receptors, a P2Y(14) receptor (GPR105) of unknown function, and anti-aggregatory A(2A) and A(2B) adenosine receptor (ARs), in addition to the ligand-gated P2X1 ion channel.

Role of Pannexin-1 hemichannels and purinergic receptors in the pathogenesis of human diseases

open access: yesFrontiers in Physiology, 2014
In the last decade several groups have determined the key role of hemichannels formed by pannexins or connexins, extracellular ATP and purinergic receptors in physiological and pathological conditions.

Purinergic mechanosensory transduction and visceral pain [PDF]

open access: yes, 2009
In this review, evidence is presented to support the hypothesis that mechanosensory transduction occurs in tubes and sacs and can initiate visceral pain.

Purinergic and Calcium Signaling in Macrophage Function and Plasticity

open access: yesFrontiers in Immunology, 2014
In addition to a fundamental role in cellular bioenergetics, the purine nucleotide adenosine triphosphate (ATP) plays a crucial role in the extracellular space as a signaling molecule.

Purinergic Signaling and Related Biomarkers in Depression

open access: yesBrain Sciences, 2020
It is established that purinergic signaling can shape a wide range of physiological functions, including neurotransmission and neuromodulation. The purinergic system may play a role in the pathophysiology of mood disorders, influencing neurotransmitter ...
