Sodium Ions Affect GPR17 Conformational States and Functionality

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Sodium is an allosteric modulator of several class‐A GPCR regulating active versus inactive conformation state and may be a critical issue for the optimization of crystallization procedures. Herein, the role of Na+ in the regulation of GPR17 conformational states was studied through MD simulations of GPR17 wild‐type and mutated on two ...

Purinergic signalling: past, present and future

Brazilian Journal of Medical and Biological Research, 2009
The discovery of non-adrenergic, non-cholinergic neurotransmission in the gut and bladder in the early 1960's is described as well as the identification of adenosine 5'-triphosphate (ATP) as a transmitter in these nerves in the early 1970's.

The bumpy road of purinergic inhibitors to clinical application in immune-mediated diseases

Neural Regeneration Research
Purinergic signaling plays important roles throughout the body in the regulation of organ functions during and following the disruption of homeostasis. This is also reflected by the widespread expression of two families of purinergic receptors (P1 and P2)

Purinergic P2X4 receptors and mitochondrial ATP production regulate T cell migration

Journal of Clinical Investigation, 2018
T cells must migrate in order to encounter antigen-presenting cells (APCs) and to execute their varied functions in immune defense and inflammation. ATP release and autocrine signaling through purinergic receptors contribute to T cell activation at the ...

Impact of sleep insufficiency and recovery on cancer development

Sleep Research, EarlyView.
Abstract Sleep plays a critical role in overall health, and modern lifestyles, such as shift work and late‐night activities, can significantly impact sleep condition. Insufficient sleep has been associated with various adverse health outcomes, including an increased risk of tumor development.

Purinergic receptors in the carotid body as a novel target for controlling hypertension

Nature Medicine, 2016
In view of the high proportion of individuals with resistance to antihypertensive medication and/or poor compliance or tolerance of this medication, new drugs to treat hypertension are urgently needed. Here we show that peripheral chemoreceptors generate

Adenosine—A Regulator of Human Testicular Peritubular Cells

Andrology, EarlyView.
ABSTRACT Background Extracellular purines, in particular ATP and adenosine, are regulators of physiological and pathophysiological processes throughout the human body. Roles in the human testis are emerging and include actions on peritubular cells, which form the wall of seminiferous tubules.

Human brain matters: Navigating the neuropathology of COVID‐19

Brain Pathology, EarlyView.
Severe COVID‐19 is associated with vascular dysregulation and chronic neuroinflammation, leading to axonal injury and neurodegeneration. In long COVID or PASC, persistent alterations in neuroimaging and biofluid biomarkers reflect ongoing neuronal damage and neuroinflammation, contributing to long‐term neurological symptoms including fatigue, cognitive

Purinergic Regulation of Neutrophil Function

Frontiers in Immunology, 2018
Purinergic signaling, which utilizes nucleotides (particularly ATP) and adenosine as transmitter molecules, plays an essential role in immune system. In the extracellular compartment, ATP predominantly functions as a pro-inflammatory molecule through ...

Activation of P2X7 and P2Y11 purinergic receptors inhibits migration and normalizes tumor-derived endothelial cells via cAMP signaling

Scientific Reports, 2016
Purinergic signaling is involved in inflammation and cancer. Extracellular ATP accumulates in tumor interstitium, reaching hundreds micromolar concentrations, but its functional role on tumor vasculature and endothelium is unknown. Here we show that high
