Amyloid β alters vascular CaV1.2 channel spatiotemporal properties

The Journal of Physiology, EarlyView.
Abstract figure legend Amyloid‐β1‐42 (Aβ1‐42) triggers a male‐specific signalling cascade influencing CaV1.2 spatiotemporal properties in cerebral vascular smooth muscle. The signalling pathway involves NADPH oxidase (NOX)‐derived reactive oxygen species (ROS) activation of protein kinase C (PKC). Aβ1‐42 can also activate protein kinase A (PKA).

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.

Potential health benefits of cold‐water immersion: the central role of PGC‐1α

The Journal of Physiology, EarlyView.
Abstract figure legend Cold‐water immersion (CWI) elicits autonomic, somato‐motoric (shivering thermogenesis), endocrine and metabolic, sensory transduction, and local biophysical effects that may converge on the transcriptional co‐activator PGC‐1α (centre).

Small‐conductance Ca2⁺‐activated K⁺ channels in cardiac excitation–contraction coupling: Bridging mitochondria, sarcolemma and antiarrhythmic therapy

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondrial SK channel enhancement reduces cardiac arrhythmia trigger. Spontaneous sarcoplasmic reticulum (SR) Ca2+ release via hyperactive RyR2s underlies an increased arrhythmia trigger, promoting early and delayed afterdepolarizations during stress. Hyperactive RyR2s causes rise in cytosolic [Ca2+] during diastole. Clearance

Glucocorticoids modulate drug transporter function in human fetal brain endothelial cells

The Journal of Physiology, EarlyView.
Abstract figure legend P‐glycoprotein and breast cancer resistance protein are the most prominent drug transporters at the fetal blood–brain barrier. We isolated primary human fetal brain endothelial cells from early and mid‐gestation cerebral microvessels and exposed them to glucocorticoids cortisol and dexamethasone in vitro.
