Purine and purinergic receptors [PDF]

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 breakdown product of adenosine 5′-triphosphate after degradation by ectonucleotidases.

Purinergic receptors in the splanchnic circulation [PDF]

open access: yesPurinergic Signalling, 2008
There is considerable evidence that purines are vasoactive molecules involved in the regulation of blood flow. Adenosine is a well known vasodilator that also acts as a modulator of the response to other vasoactive substances. Adenosine exerts its effects by interacting with adenosine receptors.

Purinergic signaling in the gastrointestinal tract [PDF]

open access: yes, 2011
Geoffrey Burnstock completed a BSc at King's College London and a PhD at University College London. He held postdoctoral fellowships with Wilhelm Feldberg (National Institute for Medical Research), Edith Bülbring (University of Oxford) and C.

Long-term (trophic) purinergic signalling: purinoceptors control cell proliferation, differentiation and death [PDF]

open access: yes, 2010
The purinergic signalling system, which uses purines and pyrimidines as chemical transmitters, and purinoceptors as effectors, is deeply rooted in evolution and development and is a pivotal factor in cell communication.

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.

Purinergic receptor mediated calcium signalling in urothelial cells [PDF]

open access: yes, 2019
Non-neuronal ATP released from the urothelium in response to bladder stretch is a key modulator of bladder mechanosensation. Whilst non-neuronal ATP acts on the underlying bladder afferent nerves to facilitate sensation, there is also the potential for ...

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 ...

Identification of atropine-and P2X1 receptor antagonist-reistant, neurogenic contractions of the urinary bladder [PDF]

open access: yes, 2007
Acetylcholine and ATP are excitatory cotransmitters in parasympathetic nerves. We used P2X1 receptor antagonists to further characterize the purinergic component of neurotransmission in isolated detrusor muscle of guinea pig urinary bladder.

Pharmacological characterization of P2X1 and P2X3 purinergic receptors in bovine chondrocytes [PDF]

open access: yes, 2008
SummaryObjectiveThe aim of the present study is that of characterizing, for the first time in a quantitative way, from a biochemical, physico chemical and functional point of view P2X1 and P2X3 purinergic receptors in bovine chondrocytes.

Activation of the P2Y2 receptor regulates bone cell function by enhancing ATP release [PDF]

open access: yes, 2017
Bone cells constitutively release ATP into the extracellular environment where it acts locally via P2 receptors to regulate bone cell function. Whilst P2Y2 receptor stimulation regulates bone mineralisation, the functional effects of this receptor in ...
