A polycystin-type transient receptor potential (Trp) channel that is activated by ATP

Biology Open, 2017
ATP and ADP are ancient extra-cellular signalling molecules that in Dictyostelium amoebae cause rapid, transient increases in cytosolic calcium due to an influx through the plasma membrane.

Dual Action of Dipyridamole in Experimental Rheumatoid Arthritis: Suppression of Joint Inflammation and Upregulation of Muscle Anabolism via Adenosine and AMPK pathways

Arthritis &Rheumatology, Accepted Article.
Introduction Rheumatoid sarcopenia, characterized by the progressive loss of skeletal muscle mass and function, is a frequent comorbidity in rheumatoid arthritis (RA), linked to prolonged, severe systemic inflammation. Purinergic signaling (adenosine, AMP, and ATP) plays a crucial role in inflammation, myogenesis, and muscle hypertrophy.

Purinergic Signaling in Liver Disease [PDF]

Digestive Diseases, 2014
Adenosine triphosphate (ATP) is essential for the myriad of metabolic processes upon which life is based and is known widely as the universal energy currency unit of intracellular biologic reactions. ATP, adenosine diphosphate, adenosine, as well as other purines and pyrimidines also serve as ubiquitous extracellular mediators which function through ...

Exosome as bioactive nanovesicle for diagnostic and therapeutic applications in periodontitis

BMEMat, EarlyView.
This review introduces the mechanism that exosomes participate in the pathogenesis of periodontitis and their potential as biomarkers for early diagnosis and summarizes the application of cell‐ or plant‐derived exosomes or engineered exosomes in periodontitis or periodontal regeneration while proposing the perspective of translational application of ...

Highlights in Purinergic Signalling [PDF]

Purinergic Signalling, 2009
It has become increasingly clear that receptors and ion channels in the plasma membrane do not exist and function in isolation, but instead form complexes with other proteins and this can modify their expression and activity. In this study, the authors determined which proteins complex with the P2X2 receptor and characterised the influence of one ...

An emerging role for adenosine and its receptors in bone homeostasis

Frontiers in Endocrinology, 2012
Bone is continually being remodelled and defects in the processes involved lead to bone diseases. Many regulatory factors are known to influence remodelling but other mechanisms, hitherto unknown, may also be involved.

OCT‐Guided Distal Left Main Bifurcation PCI: Mid‐Term Outcomes From a Multicenter South‐Asian Registry

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Optical coherence tomography (OCT)‐guided percutaneous coronary intervention (PCI) enhances treatment of complex coronary artery lesions, including left main (LM) disease, by enabling lesion morphology assessment and stent optimization, thereby reducing major adverse cardiac events (MACE).

[Purinergic signals].

Medicina, 2010
In the last decade evidence accumulated that nucleosides and nucleotides of both uridine and adenine can act as extracellular signaling factors. Their action is mediated by two main types of surface receptors commonly known as purinergic. P1 receptors are metabotropic and activated by adenosine, whereas receptors for nucleotides (ATP, ADP, UTP and UDP)

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues

ESC Heart Failure, Volume 12, Issue 2, Page 1059-1080, April 2025.
Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...

Modulatory effect of iron chelators on adenosine deaminase activity and gene expression in Trichomonas vaginalis

Memorias do Instituto Oswaldo Cruz, 2015
Trichomonas vaginalis is a flagellate protozoan that parasitises the urogenital human tract and causes trichomoniasis. During the infection, the acquisition of nutrients, such as iron and purine and pyrimidine nucleosides, is essential for the survival ...
