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

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 signaling in infection and autoimmune disease

open access: yesBiomedical Journal, 2016
Purinergic signaling plays a key role in inflammatory processes and modulates immune responses against a variety of bacterial and eukaryotic parasites.

Purinergic Signalling: Therapeutic Developments [PDF]

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 ...

Bradykinin increases resensitization of purinergic receptor signaling in glioma cells [PDF]

open access: yesCancer Cell International, 2010
Background Purinergic receptor-mediated signaling plays an important role in the function of glial cells, including glial tumor cells. Bradykinin is also an important paracrine mediator which is highly expressed in brain tumors and may correlate with ...

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.

Painful Purinergic Receptors [PDF]

open access: yesThe Journal of Pharmacology and Experimental Therapeutics, 2008
Multiple P2 receptor-mediated mechanisms exist by which ATP can alter nociceptive sensitivity following tissue injury. Evidence from a variety of experimental strategies, including genetic disruption studies and the development of selective antagonists, has indicated that the activation of P2X receptor subtypes, including P2X(3), P2X(2/3), P2X(4) and ...

Purinergic Receptors in Ocular Inflammation [PDF]

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. When inflammation affects the eye, it can produce severe disorders affecting the superficial and internal parts of the visual organ.

Purinoreceptors and ectonucleotidases control ATP-induced calcium waveforms and calcium-dependent responses in microglia: Roles of P2 receptors and CD39 in ATP-stimulated microglia

open access: yesFrontiers in Physiology, 2023
Adenosine triphosphate (ATP) and its metabolites drive microglia migration and cytokine production by activating P2X- and P2Y- class purinergic receptors.

Alterations of Purinergic Receptors Levels and Their Involvement in the Glial Cell Morphology in a Pre-Clinical Model of Autism Spectrum Disorders

open access: yesBrain Sciences, 2023
Recent data suggest that defects in purinergic signalling are a common denominator of autism spectrum disorders (ASDs), though nothing is known about whether the disorder-related imbalance occurs at the receptor level.

Purinergic Receptors: Elucidating the Role of these Immune Mediators in HIV-1 Fusion

open access: yesViruses, 2020
Purinergic receptors are inflammatory mediators activated by extracellular nucleotides released by dying or injured cells. Several studies have described an important role for these receptors in HIV-1 entry, particularly regarding their activity on HIV-1
