Purine and purinergic receptors in health and disease. [PDF]
MedComm (2020), 2023 AbstractPurines and purinergic receptors are widely distributed throughout the human body. Purine molecules within cells play crucial roles in regulating energy metabolism and other cellular processes, while extracellular purines transmit signals through specific purinergic receptors.

Purinergic receptors in airway hydration. [PDF]
Biochem Pharmacol, 2021 Airway epithelial purinergic receptors control key components of the mucociliary clearance (MCC), the dominant component of pulmonary host defense. In healthy airways, the periciliary liquid (PCL) is optimally hydrated, thus acting as an efficient lubricant layer over which the mucus layer moves by ciliary force.

The Role of Purinergic Receptors in the Circadian System. [PDF]
Int J Mol Sci, 2020 The circadian system is an internal time-keeping system that synchronizes the behavior and physiology of an organism to the 24 h solar day. The master circadian clock, the suprachiasmatic nucleus (SCN), resides in the hypothalamus. It receives information about the environmental light/dark conditions through the eyes and orchestrates peripheral ...

Role of purinergic receptors in the Alzheimer's disease. [PDF]
Purinergic Signal, 2018 AbstractEtiology of the Alzheimer’s disease (AD) is not fully understood. Different pathological processes are considered, such as amyloid deposition, tau protein phosphorylation, oxidative stress (OS), metal ion disregulation, or chronic neuroinflammation. Purinergic signaling is involved in all these processes, suggesting the importance of nucleotide

Purinergic Receptors in Ocular Inflammation [PDF]
Mediators 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.

Painful Purinergic Receptors [PDF]
The 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 ...

Epilepsia Open, EarlyView., 2022 Abstract The International League Against Epilepsy/American Epilepsy Society (ILAE/AES) Joint Translational Task Force initiated the TASK3 working group to create common data elements (CDEs) for various aspects of preclinical epilepsy research studies, which could help improve the standardization of experimental designs.

Red blood cell endothelial nitric oxide synthase: A major player in regulating cardiovascular health
British Journal of Pharmacology, EarlyView., 2023 Abstract Red blood cells (RBCs) have traditionally been seen as simple carriers of gases and nutrients in the body. One important non‐canonical function of RBCs in the cardiovascular system is the regulation of nitric oxide (NO) metabolism. It has been shown that RBCs can scavenge NO, transport NO metabolites and produce NO in hypoxic conditions ...

Purinergic receptors in airway epithelia [PDF]
Current Opinion in Pharmacology, 2009 Nucleotides and nucleosides within the airway surface liquid regulate mucociliary clearance (MCC) activities, the primary innate defense mechanism that removes foreign particles and pathogens from airway surfaces. Nucleotide and nucleoside actions in the airways are mediated mainly by two purinergic receptor subtypes, the Gq-coupled ATP/UTP-sensing ...

Purinergic mechanosensory transduction and visceral pain [PDF]
, 2009 In this review, evidence is presented to support the hypothesis that mechanosensory transduction occurs in tubes and sacs and can initiate visceral pain.
