Polydatin alleviates mitochondrial damage and apoptosis of lung epithelial cells by inhibiting toll‐like receptor 4‐dependent macrophage activation in asthma

Animal Models and Experimental Medicine, EarlyView.
The alleviation of asthma by polydatin is dependent on the blockage of the toll‐like receptor 4 (TLR4)/P2X7R synergy in macrophages. The blockage of the TLR4/P2X7R synergy results in decreased release and secretion of interleukin‐1β (IL‐1β) and IL‐18. In epithelial cells, low IL‐1β and IL‐18 levels inhibit mitochondrial damage and apoptosis.

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.

Isolation and characterization of Pisum sativum apyrases, PsNTP9 and PsNTP9-DM, cloned and expressed in Escherichia coli [PDF]

, 2019
Adenosine triphosphate (ATP) is widely known as a fuel source for many biochemical processes, and to a lesser degree also as a signaling molecule in plants and animals.

Endogenous Repair in Vanishing White Matter

Annals of Neurology, EarlyView.
Objective Vanishing white matter is a leukodystrophy with remarkable regional variation in disease severity. The cerebral and cerebellar white matter chronically degenerates, while stress‐induced episodes of rapid neurological deterioration coincide with the appearance of acute focal lesions in the deep gray structures and brainstem.

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.

Ontogeny of purinergic receptor-regulated Ca2+ signaling in mouse cortical collecting duct epithelium [PDF]

, 2002
Changes in ATP-induced increase in {[}Ca2+], during collecting duct ontogeny were studied in primary monolayer cultures of mouse ureteric bud (UB) and cortical collecting duct (CCD) cells by Fura-PE3 fluorescence ratio imaging.

Prothrombotic Activation of Platelet Pannexin 1 Channels in Antiphospholipid Syndrome

Arthritis &Rheumatology, Accepted Article.
Background ATP is released from platelets through both degranulation and pannexin‐1 (PANX1) channels. ATP then activates P2X receptors to amplify platelet activation via calcium‐dependent signaling. Objective To evaluate the role of platelet PANX1 channels in the pathophysiology of antiphospholipid syndrome (APS), an acquired thrombo‐inflammatory ...

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.

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.

Role of Nucleotide P2 Receptors in the Immune System: Focus on Effector T Cells

Cells
The emergence of purinergic signaling has given ATP and other extracellular nucleotides a whole new perspective. This concept refers to the fact that extracellular nucleotides released by most cells act as signaling molecules via specific membrane ...
