Harnessing the dual roles of pericytes to improve stroke outcomes
A/Pr Brad SutherlandPericytes are cells that are in the walls of capillaries - the smallest blood vessels. Pericytes control blood flow and help promote recovery after injury. In stroke, pericytes squeeze the capillary shut, limiting the amount of energy

Contributions of vascular ageing to late‐onset Alzheimer's disease
Experimental Physiology, EarlyView.Abstract Late‐onset Alzheimer's disease (LOAD) is an age‐related disease that is strongly associated with vascular risk factors and cerebrovascular impairments. As such, changes in the vasculature with advancing age likely contribute to LOAD, but the mechanisms underlying these contributions remain incompletely understood.

Experimental Physiology, EarlyView.Abstract Left ventricular assist devices have gained traction both as a bridge therapy and as a destination therapy in the management of heart failure. Many of these devices reinstate blood flow in a continuous manner as opposed to the pulsatile flow present in normal physiology.

TMEM16A channel signalling microdomains in the regulation of vascular function
The Journal of Physiology, EarlyView.Abstract figure legend Schematic representation of TMEM16A channel signalling microdomains. Calcium influx or calcium release from the endoplasmic/sarcoplasmic reticulum (ER/SR) activates TMEM16A channels through interactions with regulatory proteins in vascular smooth muscle cells or endothelial cells. TMEM16A channel activation drives chloride efflux,

Calcium‐activated chloride channels in pericytes and their role in regulating organ blood flow
The Journal of Physiology, EarlyView.Abstract figure legend Pericytes are microvascular mural cells with diverse roles. Contractile pericytes directly regulate local perfusion, while non‐contractile pericytes coordinate upstream vascular contractility via propagating electrical signals.

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).

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.

Physiological and anatomical determinants of placental drug transfer
The Journal of Physiology, EarlyView.Abstract figure legend Fetal exposure to pharmaceuticals and their subsequent clearance back to the maternal circulation are governed by placental transfer. Passive diffusion down a maternal‐to‐fetal concentration gradient is the primary route of fetal drug exposure, with specific compounds undergoing transporter‐mediated transfer.

The Journal of Physiology, EarlyView.Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...
