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 ...

Purines as potential morphogens during embryonic development [PDF]

open access: yes, 2012
Components of purinergic signalling are expressed in the early embryo raising the possibility that ATP, ADP and adenosine may contribute to the mechanisms of embryonic development.

Purinergic and muscarinic modulation of the cell cycle and calcium signaling in the chick retinal ventricular zone [PDF]

open access: yes, 2002
Spontaneous calcium transients occur in the ventricular zone of the chick retina and result from the endogenous release of neurotransmitters in the absence of action potentials.

Expression of P2 nucleotide receptors varies with age and sex in murine brain microglia

open access: yesJournal of Neuroinflammation, 2009
Microglia are implicated in multiple neurodegenerative disorders, many of which display sexual dimorphisms and have symptom onsets at different ages. P2 purinergic receptors are critical for regulating various microglial functions, but little is known ...

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.

New insights into purinergic receptor signaling in neuronal differentiation, neuroprotection, and brain disorders [PDF]

open access: yes, 2007
Ionotropic P2X and metabotropic P2Y purinergic receptors are expressed in the central nervous system and participate in the synaptic process particularly associated with acetylcholine, GABA, and glutamate neurotransmission. As a result of activation, the

P2X4 purinergic receptor loss alters macrophage homeostasis, cytokine secretion, and phagocytosis in a myeloid-specific P2X4 purinergic receptor knockout mouse

open access: yesFrontiers in Immunology
IntroductionThe P2X4 purinergic receptor is robustly expressed on tumor-associated macrophages; however, the role of P2X4 purinergic receptors on macrophages is not fully defined.

Adenosine-mediated modulation of ventral horn interneurons and spinal motoneurons in neonatal mice [PDF]

open access: yes, 2015
The authors are grateful for support from the Wellcome Trust.Neuromodulation allows neural networks to adapt to varying environmental and biomechanical demands. Purinergic signalling is known to be an important modulatory system in many parts of the CNS,

The Potential of Purinergic Signaling to Thwart Viruses Including SARS-CoV-2

open access: yesFrontiers in Immunology, 2022
A long-shared evolutionary history is congruent with the multiple roles played by purinergic signaling in viral infection, replication and host responses that can assist or hinder viral functions.

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.
