6‐Methylsulfinylhexyl isothiocyanate activates carbonic anhydrase‐dependent HCO3−/H+/Na+/Ca2+ transport via SLC4As–NHE–NCX–PMCA axis in odontoblasts

The Journal of Physiology, EarlyView.
Abstract figure legend 6‐Methylsulfinylhexyl isothiocyanate (6‐MSITC, hexaraphane), a wasabi sulfinyl compound, activates intracellular carbonic anhydrase (CA)‐mediated sequential HCO3−, Na+, H+ and Ca2+ transport through an activation axis involving HCO3−‐transporting solute carrier family 4 (SLC4As), the Na+–H+ exchanger (NHE), the Na+–Ca2+ exchanger

Structural Basis of Pannexin Activation [PDF]

Biophysical Journal, 2013
Pannexin 1 (Panx1) is a member of a family of large-pore ion channels distantly related to invertebrate gap junction channels, the innexins. Activation of Panx1 occurs under a variety of physiological processes, but the molecular mechanism of such activation has not in general been clearly established.

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.

Possible role of hemichannels in cancer.

Frontiers in Physiology, 2014
In humans, connexins (Cxs) and pannexins (Panxs) are the building blocks of hemichannels. These proteins are frequently altered in neoplastic cells and have traditionally been considered as tumor suppressors.

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.

Contribution of large-pore channels to inflammation induced by microorganisms

Frontiers in Cell and Developmental Biology, 2023
Plasma membrane ionic channels selectively permeate potassium, sodium, calcium, and chloride ions. However, large-pore channels are permeable to ions and small molecules such as ATP and glutamate, among others.

Targeting inflammation in cardiometabolic disease: Icosapent ethyl modulates monocyte‐derived macrophages isolated from patients with cardiovascular disease with or without type 2 diabetes

Diabetic Medicine, Volume 43, Issue 4, April 2026.
Abstract Aims Despite intensive lipid‐lowering therapy, individuals with atherosclerotic cardiovascular disease (ASCVD) exhibit residual inflammatory risk, which drives recurrent cardiovascular events. This risk is amplified in type 2 diabetes mellitus (T2DM), where a pro‐inflammatory milieu accelerates atherogenesis. Monocyte‐derived macrophages (MDMs)

N-Glycosylation Regulates Pannexin 2 Localization but Is Not Required for Interacting with Pannexin 1 [PDF]

International Journal of Molecular Sciences, 2018
Pannexins (Panx1, 2, 3) are channel-forming glycoproteins expressed in mammalian tissues. We previously reported that N-glycosylation acts as a regulator of the localization and intermixing of Panx1 and Panx3, but its effects on Panx2 are currently unknown.

Astrocyte Bioenergetic Remodeling as a Central Trait of Disrupted Glucocorticoid Signaling: Mechanisms and Implications for Stress Vulnerability

Journal of Neurochemistry, Volume 170, Issue 3, March 2026.
Low/brief glucocorticoid (GC) elevations can enhance mitochondrial output (↑ oxygen consumption rate, OCR; ↑ mitochondrial membrane potential, ΔΨm) and Ca2+ buffering, in part via glucocorticoid receptor (GR) trafficking to mitochondria in complexes with Bcl2 and Bag1.
