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.

Revisiting multimodal activation and channel properties of Pannexin 1 [PDF]

Journal of General Physiology, 2017
Pannexin 1 (Panx1) forms plasma membrane ion channels that are widely expressed throughout the body. Panx1 activation results in the release of nucleotides such as adenosine triphosphate and uridine triphosphate. Thus, these channels have been implicated in diverse physiological and pathological functions associated with purinergic signaling, such as ...

P2X7 Receptors as a Therapeutic Target in Cerebrovascular Diseases

Frontiers in Molecular Neuroscience, 2020
Shortage of oxygen and nutrients in the brain induces the release of glutamate and ATP that can cause excitotoxicity and contribute to neuronal and glial damage.

An unattended image‐processing pipeline for on‐the‐fly quality assessment and 3D exploration in cryo‐EM

Acta Crystallographica Section D, Volume 82, Issue 8, Page 915-939, August 2026.
We present a fully automated, unattended cryo‐EM pipeline that serves as an on‐the‐fly diagnostic tool, enabling rapid data‐quality assessment and informed decision‐making to maximize data‐collection efficiency.Single‐particle analysis (SPA) by cryogenic electron microscopy (cryo‐EM) has become a cornerstone of structural biology; yet, the workflow ...

Platelet pannexin-1 channels modulate neutrophil activation and migration but not the progression of abdominal aortic aneurysm

Frontiers in Molecular Biosciences, 2023
Abdominal aortic aneurysm (AAA) is a common disease and highly lethal if untreated. The progressive dilatation of the abdominal aorta is accompanied by degradation and remodeling of the vessel wall due to chronic inflammation.

Astrocyte Mechanobiology: Linking Biomechanical Forces to Biochemical Signaling in the Central Nervous System

Glia, Volume 74, Issue 7, July 2026.
Astrocytes are key sensors and transducers of biomechanical stimuli within the central nervous system. Astrocyte development is highly dependent on mechanical stimuli such as surrounding tissue stiffness and biomechanical strain. Mechanosensory pathways including integrins, connexins and pannexins, and mechanosensitive channels regulate astrocyte ...

The Multifaceted Role of Pyroptosis: Molecular Mechanisms, Crosstalk with Other Cell Death Pathways, and Therapeutic Implications

MedComm, Volume 7, Issue 7, July 2026.
Pyroptosis maintains immune homeostasis by eliminating damaged or infected cells, but its dysregulation promotes inflammation and cancer progression. The diagram illustrates key activation pathways, links with other programmed cell deaths, and cancer‐specific effects, enhancing its dual protective and pathogenic roles.

When can AlphaFold predict the oligomeric states of proteins?

Protein Science, Volume 35, Issue 7, July 2026.
Abstract Homooligomerisation is a prevalent and important process that many proteins undergo to form the quaternary structures required for biological function. However, determining oligomeric states and structures experimentally remains technically challenging and time‐consuming for many proteins.
