Adenosine Inhibits the Excitatory Synaptic Inputs to Basal Forebrain Cholinergic, GABAergic and Parvalbumin Neurons in mice [PDF]

Frontiers in Neurology, 2013
Coffee and tea contain the stimulants caffeine and theophylline. These compounds act as antagonists of adenosine receptors. Adenosine promotes sleep and its extracellular concentration rises in association with prolonged wakefulness, particularly in the ...

Anti-inflammatory preconditioning by agonists of adenosine A1 receptor. [PDF]

PLoS ONE, 2008
BackgroundAdenosine levels rise during inflammation and modulate inflammatory responses by engaging with four different G protein-coupled receptors. It is suggested that adenosine exhibits pro-inflammatory effects through its A(1) receptor (A(1)R), and ...

Multisite Model of Allosterism for the Adenosine A1 Receptor [PDF]

Journal of Chemical Information and Modeling, 2020
ABSTRACTDespite being a target for about one-third of approved drugs, G protein-coupled receptors (GPCRs) still represent a tremendous reservoir for therapeutic strategies against countless diseases. For example, several cardiovascular and central nervous systems conditions could benefit from clinical agents that activate the adenosine 1 receptor (A1R),

Rapid Eye Movement Sleep Deprivation Combined With Fluoxetine Protects Against Depression-Induced Damage and Apoptosis in Rat Hippocampi via A1 Adenosine Receptor

Frontiers in Psychiatry, 2021
Background: Rapid eye movement sleep deprivation (REMSD) and fluoxetine affect depression, yet the detailed molecular mechanisms were not clear.Methods: Rat depression chronic unpredictable stress was constructed, and the body weight of rats was measured.

Deciphering the Agonist Binding Mechanism to the Adenosine A1 Receptor [PDF]

ACS Pharmacology & Translational Science, 2020
ABSTRACTDespite being amongst the most characterized G protein-coupled receptors (GPCRs), adenosine receptors (ARs) have always been a difficult target in drug design. To date, no agonist other than the natural effector and the diagnostic regadenoson has been approved for human use.

Adenosine receptors in GtoPdb v.2021.2 [PDF]

, 2021
Adenosine receptors (nomenclature as agreed by the NC-IUPHAR Subcommittee on Adenosine Receptors [110]) are activated by the endogenous ligand adenosine (potentially inosine also at A3 receptors).

Immunolocalization of A1 Adenosine Receptors in Mammalian Spermatozoa [PDF]

Journal of Histochemistry & Cytochemistry, 2000
The presence of A1 adenosine receptors (A1AR) in mammalian spermatozoa was previously demonstrated by radiochemical and immunochemical detection. This study was performed to investigate the cellular location of the A1AR to determine whether these receptors were somehow connected with ecto-adenosine deaminase and to evaluate their function in calcium ...

Mitochondrial stress in advanced fibrosis and cirrhosis associated with chronic hepatitis B, chronic hepatitis C, or nonalcoholic steatohepatitis

Hepatology, EarlyView., 2022
Adaptive mitochondrial mechanisms allow mitochondrial resilience and prevent the worsening of fibrosis, while deregulation of these mechanisms promotes the progression from no/minimal‐mild (F0‐F2) fibrosis to advanced fibrosis and cirrhosis (F3‐F4). Abstract Background and Aims Hepatitis B virus (HBV) infection causes oxidative stress (OS) and alters ...

Adenosine stimulates the basolateral 50 pS K+ channel in renal proximal tubule via adenosine-A1 receptor

Frontiers in Physiology, 2023
Background: The basolateral potassium channels play an important role in maintaining the membrane transport in the renal proximal tubules (PT) and adenosine receptors have been shown to regulate the trans-epithelial Na+ absorption in the PT.
