Pathophysiological Role of Extracellular Purinergic Mediators in the Control of Intestinal Inflammation

Mediators of Inflammation, 2015
Purinergic mediators such as adenosine 5′-triphosphate (ATP) are released into the extracellular compartment from damaged tissues and activated immune cells. They are then recognized by multiple purinergic P2X and P2Y receptors.

Purinergic Signaling in the Pathophysiology and Treatment of Huntington’s Disease

Frontiers in Neuroscience, 2021
Huntington’s disease (HD) is a devastating, progressive, and fatal neurodegenerative disorder inherited in an autosomal dominant manner. This condition is characterized by motor dysfunction (chorea in the early stage, followed by bradykinesia, dystonia ...

Disengaging the Engine: Histone Deacetylases 1 and 2‐Mediated Acetylation of Hexokinase‐2 Regulates Energy Metabolism in Microglia Following Intracerebral Hemorrhage

Advanced Science, EarlyView.
This study demonstrates that HDAC1/2 knockout in microglia alleviates neurological deficits, preserves white matter, and accelerates hematoma clearance after ICH. HDAC1/2 inhibition reduces HK2 acetylation, shifts metabolism from glycolysis to fatty acid oxidation, reduces inflammation, and enhances phagocytosis.

Purines, Purinergic Receptors, and Cancer [PDF]

Cancer Research, 2012
AbstractPurines were long thought to be restricted to the intracellular compartment, where they are used for energy transactions, nucleic acid synthesis, and a multiplicity of biochemical reactions. However, it is now clear that both adenosine and adenosine triphosphate are (i) abundant biochemical components of the tumor microenvironment, (ii) potent ...

Midbrain PAG Astrocytes Modulate Mouse Defensive and Panic‐Like Behaviors

Advanced Science, EarlyView.
Astrocytes in the midbrain periaqueductal gray (PAG) dynamically encode threat intensity and shape defensive action selection in mice. Real‐time Ca2+ imaging reveals robust astrocytic activation during predator odor and CO2 exposure. Aberrant astrocytic Ca2+ overactivation disrupts goal‐directed escape, biases behavior toward freezing, and induces ...

Mechanisms of astrocytic and microglial purinergic signaling in homeostatic regulation and implications for neurological disease [PDF]

Exploration of Neuroscience
Purinergic signaling, mediated by ATP and adenosine receptors, plays a crucial role in cellular communication and homeostasis within the central nervous system (CNS), particularly by regulating synaptic activity, glial cell functions, and neuroplasticity.

OTUD6A in Airway Epithelial Cells Exacerbates Allergic Asthma by Promoting Airway Inflammation and Airway Remodeling Through Deubiquitination of hResistin/mRELMα

Advanced Science, EarlyView.
This study elucidates a novel mechanistic role of the deubiquitinase OTUD6A in asthma pathogenesis, uncovering its regulatory function in airway inflammation and airway remodeling through the stabilization of hResistin/mRELMα. This study offers a novel regulatory axis (OTUD6A‐hResistin/mRELMα) in asthma pathogenesis and OTUD6A inhibition as a potential

Depletion of the RNA‐Editing Enzyme ADAR1 Invigorates the Antitumor Immunity of NK Cells

Advanced Science, EarlyView.
ADAR1 is upregulated in NK cells from melanoma patients, impairing their function. Its loss enhances NK cell tumor infiltration and cytotoxicity in vitro and in vivo. Mechanistically, ADAR1 deficiency destabilizes CD38 mRNA to reduce its expression, thereby increasing NK cell mobility and killing, which nominates it as a therapeutic target for NK cell ...

Biology of Platelet Purinergic Receptors and Implications for Platelet Heterogeneity

Frontiers in Pharmacology, 2018
Platelets are small anucleated cells present only in mammals. Platelets mediate intravascular hemostatic balance, prevent interstitial bleeding, and have a major role in thrombosis.

Metabolic Changes Induced by Purinergic Signaling: Role in Food Intake

Frontiers in Pharmacology, 2021
The purinergic signalling has a well-established role in the regulation of energy homeostasis, but there is growing evidence of its implication in the control of food intake.
