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 Signaling During Hyperglycemia in Vascular Smooth Muscle Cells

Frontiers in Endocrinology, 2020
The activation of purinergic receptors by nucleotides and/or nucleosides plays an important role in the control of vascular function, including modulation of vascular smooth muscle excitability, and vascular reactivity.

SLC25A4high Hepatocytes Enhance Lifestyle Intervention Response in MASLD by Recruiting Eating Macrophages

Advanced Science, EarlyView.
SLC25A4high hepatocytes drive metabolic‐associated steatotic liver disease (MASLD) remission by recruiting lipid‐eating macrophages. The hepatocyte Slc25a4/PANX1/ATP/P2ry12 axis mediates find‐me signaling that triggers macrophage recruitment and efferocytosis, while recruited macrophages secrete GDF15 to activate hepatocyte PPARα and promote fatty acid

Clock Genes Regulate Ca2+ Signaling and Mitochondrial Bioenergetics to Inhibit Sjögren Disease

Arthritis &Rheumatology, EarlyView.
Objective Although Ca2+ signaling and metabolism have been identified as key determinants for the development of Sjögren disease (SjD), the intricate connection between them and salivary gland physiology remains poorly understood. Methods Fluorescence‐based Ca2+ imaging, RNA sequencing, and mitochondrial activity were used to investigate the effects of

Purinergic signaling in inflammatory cells: P2 receptor expression, functional effects, and modulation of inflammatory responses

, 2013
Extracellular ATP and related nucleotides promote a wide range of pathophysiological responses via activation of cell surface purinergic P2 receptors. Almost every cell type expresses P2 receptors and/or exhibit regulated release of ATP.

Purinergic receptors in the splanchnic circulation [PDF]

Purinergic Signalling, 2008
There is considerable evidence that purines are vasoactive molecules involved in the regulation of blood flow. Adenosine is a well known vasodilator that also acts as a modulator of the response to other vasoactive substances. Adenosine exerts its effects by interacting with adenosine receptors.

PRDM16 is necessary for sensory neuronal development and differentiation in the trigeminal ganglion

Developmental Dynamics, EarlyView.
Abstract Background Cranial neural crest cells (cNCC) generate craniofacial cartilage, bone, and peripheral neurons and glia, and birth defects arise when the cartilage/neuronal/glial progenitors fail to differentiate. PRDM16 is a transcriptional regulator containing both zinc‐finger and SET domains, implicated in craniofacial development and orofacial

Purinergic signaling via P2X receptors and mechanisms of unregulated ATP release in the outer retina and age-related macular degeneration

Frontiers in Neuroscience, 2023
Age-related macular degeneration (AMD) is a chronic and progressive inflammatory disease of the retina characterized by photoceptor loss and significant central visual impairment due to either choroidal neovascularization or geographic atrophy.

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 ...

Activation of adenosine A_2B receptors enhances ciliary beat frequency in mouse lateral ventricle ependymal cells

Cerebrospinal Fluid Research, 2009
Background Ependymal cells form a protective monolayer between the brain parenchyma and cerebrospinal fluid (CSF). They possess motile cilia important for directing the flow of CSF through the ventricular system.
