Purinergic signaling in hepatic disease [PDF]

Purinergic Signalling, 2019
Extracellular purines (ATP and adenosine) are ubiquitous intercellular messengers. During tissular damage, they function as damage-associated molecular patterns (DAMPs). In this context, purines announce tissue alterations to initiate a reparative response that involve the formation of the inflammasome complex and the recruitment of specialized cells ...

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 ...

Function‐centered back‐tracing refines obesity‐associated gut microbiome signals beyond abundance‐based profiling

iMetaOmics, EarlyView.
By integrating taxonomic and functional profiling of 1543 adult gut metagenomes, this study identified microbial taxa and enzymatic functions associated with increasing Body Mass Index. Function‐centered taxonomic back‐tracing of branched‐chain amino acid transaminase, nucleotide diphosphatase, and phosphatidylserine decarboxylase revealed only limited

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.

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.

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.

Na+ absorption by Claudius’ cells is regulated by purinergic signaling in the cochlea [PDF]

, 2012
Conclusion: Claudius’ cells absorb Na+ through the amiloride-sensitive epithelial sodium channel (ENaC). Transepithelial ion transport through ENaC and possibly a Cl[superscript]- secretory pathway is regulated by P2Y purinergic signaling.

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 ...

Multifaceted Effects of Extracellular Adenosine Triphosphate and Adenosine in the Tumor–Host Interaction and Therapeutic Perspectives

Frontiers in Immunology, 2017
Cancer is still one of the world’s most pressing health-care challenges, leading to a high number of deaths worldwide. Immunotherapy is a new developing therapy that boosts patient’s immune system to fight cancer by modifying tumor–immune cells ...
