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.

Diabetes‐Induced Dysregulation of Purinergic Signaling in the Bladder Mucosa: Accelerated ATP Hydrolysis and Impaired Adenosine Uptake Promote Underactive Bladder Phenotype

Neurourology and Urodynamics, EarlyView.
ABSTRACT Objective To explore molecular mechanisms underlying excessive extracellular adenosine (ADO) accumulation in the bladder lamina propria (LP) of mice with type 2 diabetes (T2D) induced by a high‐fat, high‐sucrose diet (HFHSD), conceivably leading to bladder underactivity.

Repurposing antimicrobial agents for neuroprotection: Mechanisms, clinical potential, and challenges

Neuroprotection, EarlyView.
Antimicrobial agents exert neuroprotective effects through modulation of interconnected pathways. Tetracyclines, macrolides, antimalarial agents, sulfones, and antiparasitic agents suppress neuroinflammation, oxidative stress, and apoptosis while preserving mitochondrial function and neurotransmission.

Purinergic receptors in skeletal muscles in health and in muscular dystrophy [PDF]

, 2014
The P2 purinergic (nucleotide) receptor super-family comprises of two families of protein. The P2X, which are channel-forming ionotropic receptors and the P2Y metabotropic receptors activating G protein-mediated signalling pathways.

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.

Mesenchymal stem cells as cellular factories for targeted P2X7 blockade after traumatic brain injury

Neuroprotection, EarlyView.
This manuscript presents a novel therapeutic strategy using mesenchymal stem cells (MSCs) engineered as living drug factories to deliver a P2X7‐blocking nanobody for treatment of ischemic stroke. By combining targeted cellular delivery with sustained local immunomodulation, the approach aims to overcome key limitations of systemic biologic ...

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 ...

Purine and purinergic receptors

Brain and Neuroscience Advances, 2018
Adenosine 5′-triphosphate acts as an extracellular signalling molecule (purinergic signalling), as well as an intracellular energy source. Adenosine 5′-triphosphate receptors have been cloned and characterised. P1 receptors are selective for adenosine, a

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 ...

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.
