Catecholaminergic polymorphic ventricular tachycardia–linked ryanodine receptor variants exhibit domain‐specific calcium leak and calmodulin affinity properties

The Journal of Physiology, EarlyView.
Abstract figure legend Catecholaminergic polymorphic ventricular tachycardia (CPVT) variants in N terminal (NTD) and central domain (CD) but not pore domain induce a pathological RyR2 conformational shift upon protein kinase A (PKA) phosphorylation, similar to that seen in heart failure (HF), calcium/calmodulin‐dependent protein kinase II (CaMKII ...

Lactate potentiates NMDA receptor currents via an intracellular redox mechanism targeting GluN2B subunits: implications for synaptic plasticity

The Journal of Physiology, EarlyView.
Abstract figure legend Astrocyte‐derived lactate enhances neuronal NMDA receptor (NMDAR) function and synaptic plasticity through a redox‐ and CaMKII‐dependent mechanism. Lactate enters neurons via monocarboxylate transporters (MCTs) and is oxidized by lactate dehydrogenase (LDH) to pyruvate, generating NADH and increasing the intracellular NADH/NAD ...

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

The 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.

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.

Physiological mechanisms underlying enhanced performance with blood flow restriction training: neuromuscular, vascular and metabolic adaptations

The Journal of Physiology, EarlyView.
Abstract figure legend We investigated how 6 weeks of dynamic knee‐extensor interval training with blood flow restriction (BFR‐leg) and without (CTRL‐leg) impacts performance and its mechanisms using non‐invasive methods. Specifically, we used gold‐standard methods to assess neuromuscular function, vascular function using Doppler ultrasound, and near ...
