The role of purinergic signaling in microglial responses

Stress and Brain, 2021
Microglia, the primary immune cells in the central nervous system (CNS), are key to the maintenance of homeostasis in the brain parenchyma. In the intact brain, microglia continuously survey the microenvironment with ramified processes.

TMEM16A channel signalling microdomains in the regulation of vascular function

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic representation of TMEM16A channel signalling microdomains. Calcium influx or calcium release from the endoplasmic/sarcoplasmic reticulum (ER/SR) activates TMEM16A channels through interactions with regulatory proteins in vascular smooth muscle cells or endothelial cells. TMEM16A channel activation drives chloride efflux,

Identification of atropine-and P2X1 receptor antagonist-reistant, neurogenic contractions of the urinary bladder

, 2007
Acetylcholine and ATP are excitatory cotransmitters in parasympathetic nerves. We used P2X1 receptor antagonists to further characterize the purinergic component of neurotransmission in isolated detrusor muscle of guinea pig urinary bladder.

Ectonucleotidases CD39 and CD73 expression levels are independent and inverse predictors of survival in muscle‐invasive bladder cancer

The Journal of Pathology: Clinical Research, Volume 12, Issue 4, July 2026.
Abstract Bladder cancer is one of the leading causes of cancer‐related mortality worldwide. Long‐term survival is particularly poor in patients with muscle‐invasive bladder cancer (MIBC). Modulation of purinergic signaling through the ectonucleotidases CD39 and CD73 has emerged as a promising therapeutic strategy in cancer medicine.

Astrocyte Mechanobiology: Linking Biomechanical Forces to Biochemical Signaling in the Central Nervous System

Glia, Volume 74, Issue 7, July 2026.
Astrocytes are key sensors and transducers of biomechanical stimuli within the central nervous system. Astrocyte development is highly dependent on mechanical stimuli such as surrounding tissue stiffness and biomechanical strain. Mechanosensory pathways including integrins, connexins and pannexins, and mechanosensitive channels regulate astrocyte ...

Role of purinergic signalling in obesity-associated end-organ damage: focus on the effects of natural plant extracts

Frontiers in Endocrinology, 2023
Obesity has become one of the major public health problems in both the developing and developed countries. Recent studies have suggested that the purinergic signalling is involved in obesity-associated end-organ damage through purine P1 and P2 receptors.

Purinergic and muscarinic modulation of the cell cycle and calcium signaling in the chick retinal ventricular zone

, 2002
Spontaneous calcium transients occur in the ventricular zone of the chick retina and result from the endogenous release of neurotransmitters in the absence of action potentials.

Neurochemical Changes in the Mouse Hippocampus Underlying the Antidepressant Effect of Genetic Deletion of P2X7 Receptors. [PDF]

, 2013
Recent investigations have revealed that the genetic deletion of P2X7 receptors (P2rx7) results in an antidepressant phenotype in mice. However, the link between the deficiency of P2rx7 and changes in behavior has not yet been explored.

Pathways of Protein Secretion in Prokaryotes and Eukaryotes: Molecular Mechanisms, Biological Functions, and Therapeutic Opportunities

MedComm, Volume 7, Issue 6, June 2026.
This graphical abstract delineates noncanonical protein secretion systems across eukaryotes and prokaryotes. Eukaryotic UcPS covers four ER–Golgi bypass pathways, enabling rapid leaderless protein export via direct transmembrane translocation or vesicle‐mediated release.

Adenosine-mediated modulation of ventral horn interneurons and spinal motoneurons in neonatal mice

, 2015
The authors are grateful for support from the Wellcome Trust.Neuromodulation allows neural networks to adapt to varying environmental and biomechanical demands. Purinergic signalling is known to be an important modulatory system in many parts of the CNS,
