Non‐ionotropic NMDAR signalling activates Panx1 to induce P2X4R‐dependent long‐term depression in the hippocampus

The Journal of Physiology, EarlyView.
Abstract figure legend Stimulation of the Shaffer collateral pathway at 3 Hz activates non‐ionotropic NMDA receptors. This subsequently leads to Src kinase mediated phosphorylation of pannexin‐1 (Panx1), which releases ATP from the postsynaptic cell. ATP acts as a ligand for P2X4 receptors to induce long‐term depression (LTD). Abstract In recent years,

Recent advances in the structure, function and regulation of the volume‐regulated anion channels and their role in immunity

The Journal of Physiology, EarlyView.
Abstract figure legend The volume‐regulated anion channel (VRAC), composed of leucine‐rich repeat‐containing 8 (LRRC8) proteins, serves both canonical and non‐canonical functions in vertebrate cells. The canonical function of this channel relates to its original description, which is homeostatic regulation of cell volume in response to hypotonic ...

Dual role for pannexin 1 at synapses: regulating functional and morphological plasticity

The Journal of Physiology, EarlyView.
Abstract figure legend Pannexin 1 (PANX1) regulation of dendritic spines. The postnatal decrease in PANX1 expression could release key spine cytoskeleton‐regulating proteins enabling spine stabilization. Does the physiological decrease in neuronal PANX1 levels across brain development underlie dendritic spine maturation?

Inhibition and potentiation of the exercise pressor reflex by pharmacological modulation of TRPC6 in male rats

The Journal of Physiology, EarlyView.
Abstract figure legend The majority of L4–L5 dorsal root ganglion cells innervating the triceps surae muscles of healthy rats expressed TRPC6 channels. In decerebrated rats, pharmacological inhibition of TRPC6 channels by injection of antagonists (SAR7334 or BI‐749327) into the arterial supply of the triceps surae muscles inhibited the exercise pressor

Sphingosine‐1‐phosphate activates LRRC8 volume‐regulated anion channels through Gβγ signalling

The Journal of Physiology, EarlyView.
Abstract figure legend Sphingosine‐1‐phosphate (S1P) binds to Gi protein‐coupled receptor S1PR1. Upon S1PR1 activation, Gβγ is released from the Gαi‐Gβγ heterotrimer, allowing it to recruit phospholipase Cβ (PLCβ) to the plasma membrane. PLCβ cleaves phosphatidylinositol‐4,5‐bisphosphate (PIP2) into inositol trisphosphate (IP3) and diacylglycerol (DAG).

Evidence for control of cerebral neurovascular function by circulating platelets in healthy older adults

The Journal of Physiology, EarlyView.
Abstract figure legend Epidemiological evidence suggests a link between dementia and cardiovascular health, including the regulation of platelets. To investigate this relationship, we examined how platelet reactivity relates to cerebral neurovascular function and systemic vascular reactivity in healthy older adults.

Targeting Connexin 43 in Retinal Astrocytes Promotes Neuronal Survival in Glaucomatous Injury

Glia, Volume 73, Issue 7, Page 1398-1419, July 2025.
Main Points Astrocytes play an important role in glaucoma. These cells express Cx43 which can form gap junctions and hemichannels. This study shows Cx43 deletion in astrocytes provides neuroprotection in glaucoma, possibly through hemichannel activation.

ROLE OF PURINERGIC RECEPTORS IN IMMUNE RESPONSE

Journal of microbiology, epidemiology and immunobiology, 2016
Purine receptors are located on immune and somatic cells of animal and human organisms. Summation of signals from purine and TOLL-like receptors takes place on the level of inflammasome formation and results in summation of the first and second signals of innate immunity.

Potassium‐Dependent Coupling of Retinal Astrocyte Light Response to Müller Glia

Glia, Volume 73, Issue 7, Page 1520-1534, July 2025.
Main Points Astrocytes depolarize to light ON and OFF like Müller glia. The astrocyte light response is due to potassium influx. Retinal macroglial current‐voltage responses exhibit rectification which changes with repeated stimulation. ABSTRACT Astrocytes throughout the central nervous system mediate a variety of functions to support proper tissue ...

Investigating the Mechanism of Conditioning Versus Postoperative Electrical Stimulation to Enhance Nerve Regeneration: One Therapy, Two Distinct Effects

Muscle &Nerve, Volume 72, Issue 1, Page 15-33, July 2025.
ABSTRACT Regeneration after peripheral nerve injury is often insufficient for functional recovery. Postoperative electrical stimulation (PES) following injury and repair significantly improves clinical outcomes; recently, conditioning electrical stimulation (CES), delivered before nerve injury, has been introduced as a candidate for clinical ...
