Energetic microdomains and the vascular control of neuronal and muscle excitability: Toward a unified model

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The capillary–mitochondria–ion channel (CMIC) axis scales structural resources to match functional workload. (Left) In settings of restricted energetic capacity (e.g. cortical neurons), sparse capillary networks and modest mitochondrial pools set a lower energetic ceiling, sufficient to support phasic, low‐workload excitability.

High‐altitude headache: Insights into pathophysiology and potential treatment implications

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude headache occurs during prolonged exposure to low oxygen, such as during ascent to high altitude. Several risk factors increase its likelihood, with the degree of hypoxia, often driven by rapid ascent to greater altitudes, being the most prominent factor.

Age- and Experience-Related Plasticity of ATP-Mediated Signaling in the Neocortex

open access: yesFrontiers in Cellular Neuroscience, 2019
There is growing recognition of the important role of interaction between neurons and glial cells for brain longevity. The extracellular ATP have been shown to bring significant contribution into bi-directional glia-neuron communications, in particular ...

Trichomoniasis immunity and the involvement of the purinergic signaling

open access: yesBiomedical Journal, 2016
Innate and adaptive immunity play a significant role in trichomoniasis, the most common non-viral sexually transmitted disease worldwide. In the urogenital tract, innate immunity is accomplished by a defense physical barrier constituted by epithelial ...

P2X3 receptor antagonism improves hindlimb blood flow during exercise in a conscious ovine model of hypertensive heart failure with preserved ejection fraction

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend A preclinical large‐animal model of hypertensive heart failure with preserved ejection fraction (HFpEF) was used to examine the role of purinergic P2X3 receptor signalling during treadmill exercise. Animals were instrumented with either thoracic cardiac output and coronary flow probes or abdominal renal and hindlimb blood flow ...

KV channels contribute to thermal hyperaemia in skeletal muscle of humans

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Using skeletal muscle microdialysis and pulsed short‐wave diathermy, we examined the contribution of KV channels to thermal hyperaemia in human skeletal muscle. KV channel antagonism with 4‐aminopyridine attenuated thermal hyperaemia by ∼65%, identifying a critical downstream role for these ion channels in the vasodilatory ...

Genome‐Wide Analysis of Resistance to Gastrointestinal Parasites in Portuguese Merino and Merino‐Related Sheep

open access: yesAnimal Genetics, Volume 57, Issue 6, December 2026.
ABSTRACT Gastrointestinal nematodes (GIN) are one of the main constraints affecting sheep production worldwide. For decades, control methods based on anthelmintics have been extensively used, which ended up in multiple drug‐resistant helminth strains.

Purinergic signaling in the inner ear

open access: yes, 2007
Epithelial cells of the inner ear coordinate their ion transport activity through a number of mechanisms. One important mechanism is the autocrine and paracrine signaling among neighboring cells in the ear via nucleotides, such as adenosine, ATP and UTP.
