Cells and ionic conductances contributing to spontaneous activity in bladder and urethral smooth muscle

The Journal of Physiology, EarlyView.
Abstract figure legend Cells and conductances contributing to spontaneous activity in the lower urinary tract. Bladder and urethra exhibit spontaneous contractions at both cellular and tissue levels. Both detrusor and urethral smooth muscle cells display activity that is regular and rhythmic.

Pharmacologic inhibition by spironolactone attenuates experimental abdominal aortic aneurysms

Frontiers in Cardiovascular Medicine, 2023
BackgroundAbdominal aortic aneurysms (AAA) are characterized by vascular inflammation and remodeling that can lead to aortic rupture resulting in significant mortality. Pannexin-1 channels on endothelial cells (ECs) can modulate ATP secretion to regulate

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

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.

Pannexin 1 in the Regulation of Vascular Tone [PDF]

Trends in Cardiovascular Medicine, 2012
Pannexins are a recently discovered protein family with the isoform Panx1 ubiquitously expressed and therefore extensively studied. Panx1 proteins form membrane channels known to release purines such as ATP. Because ATP and, more generally, purinergic signaling plays an important role in the vasculature, it became evident that Panx1 could have a key ...

Intrinsic properties and regulation of Pannexin 1 channel [PDF]

Channels, 2014
Pannexin 1 (Panx1) channels are generally represented as non-selective, large-pore channels that release ATP. Emerging roles have been described for Panx1 in mediating purinergic signaling in the normal nervous, cardiovascular, and immune systems, where they may be activated by mechanical stress, ionotropic and metabotropic receptor signaling, and via ...

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)

Herb-partitioned moxibustion alleviates colonic inflammation in Crohn's disease rats by inhibiting hyperactivation of the NLRP3 inflammasome via regulation of the P2X7R-Pannexin-1 signaling pathway.

PLoS ONE, 2021
Crohn's disease is a chronic inflammatory bowel disease and the NLRP3 inflammasome plays an important role in Crohn's disease. Previous studies have shown that Herb-partitioned moxibustion treating (at Qihai (CV 6) and Tianshu (ST 25)) prevented the ...

The platelet pannexin 1-IL-1β axis orchestrates pancreatic ductal adenocarcinoma invasion and metastasis

Oncogene, 2023
We aimed to investigate the protumor mechanisms of platelets in pancreatic ductal adenocarcinoma (PDAC). Serum samples were collected from 656 PDAC patients and 3105 healthy people, and a Panx1 knockout tumor model and an adoptive platelet transfusion ...
