Demonstration of beat‐to‐beat, on‐demand ATP synthesis in ventricular myocytes reveals sex‐specific mitochondrial and cytosolic dynamics

The Journal of Physiology, EarlyView.
Abstract figure legend Beat‐locked mitochondrial ATP transients reveal modular, sex‐specific bioenergetic control during excitation–contraction coupling. A, each action potential activates L‐type CaV1.2 channels, producing a Ca2+ influx that triggers ryanodine receptors (RyR2) and elicits SR Ca2+ release.

When NCX switches sides: Experimental and computational insights into Ca2+ regulation in the heart

The Journal of Physiology, EarlyView.
Abstract figure legend Due to its presence inside the dyadic cleft, Na+/Ca2+ exchanger (NCX) builds a functional unit together with L‐type calcium channels and ryanodine receptors in the dyadic cleft. NCX acts bidirectionally (forward and reverse mode) dependent on extracellular calcium ([Ca2+]o) and sodium ([Na+]o) concentrations and the membrane ...

Oleuropein‐based olive leaf extract enhances muscle mitochondrial bioenergetics response to moderate – but not maximal – intensity exercise in humans

The Journal of Physiology, EarlyView.
Abstract figure legend In a double‐blind, crossover study, we observed that olive leaf extract (OLE) intake combined with a single session of moderate‐intensity continuous exercise (MICE) significantly enhanced skeletal muscle mitochondrial bioenergetics, whereas this effect was milder when OLE was combined with sprint interval exercise (SIE ...

Coordinated regulation of PIEZO2 by alternative splicing, post‐translational modification, membrane trafficking and protein partners

The Journal of Physiology, EarlyView.
Abstract figure legend Regulatory mechanisms such as alternative splicing, post‐translational modification, membrane trafficking, and protein interactions control channel gating, membrane abundance, and overall activity of PIEZO2. Proper regulation supports PIEZO2‐dependent proprioceptive, somatosensory, nociceptive, pruriceptive and interoceptive ...

Drafting the calmodulation playbook: Emerging structural insights into transient receptor potential channel regulation by calmodulin

The Journal of Physiology, EarlyView.
Abstract figure legend Calmodulin (CaM) is a ubiquitous calcium (Ca2+) sensor that translates intracellular Ca2+ signals into modulation of hundreds of effector proteins including ion channels. CaM is increasingly recognized as a key regulator of the transient receptor potential (TRP) channel family, yet the underlying ‘calmodulation playbook’ is only ...

Cardiovascular β‐Adrenergic Receptor Distribution and Function: Influence of Species, Sex, Age, and Tissue

Comprehensive Physiology, Volume 16, Issue 3, June 2026.
Estrogen modulates β‐AR signaling in a context‐dependent manner influenced by species, sex, age, tissue, and vascular health, highlighting challenges in translating findings from experimental models to human cardiovascular physiology. ABSTRACT Cardiovascular diseases remain the leading global cause of morbidity and mortality, with notable sex‐specific ...

The Recycling Endosomal (Na+, K+)/H+ Exchanger NHE6/SLC9A6 Facilitates Signal Transduction by Shuttling Cyclin‐Dependent Kinase 5 to the Plasma Membrane

Acta Physiologica, Volume 242, Issue 6, June 2026.
ABSTRACT Aim The alkali cation/proton exchanger NHE6/SLC9A6 regulates luminal pH homeostasis and trafficking of recycling endosomes in most tissues, especially neurons. Loss‐of‐function mutations in NHE6 cause Christianson Syndrome, an X‐linked neurodevelopmental and neurodegenerative disorder; however, the underlying molecular and cellular mechanisms ...
