Tonabersat suppresses priming/activation of the NOD-like receptor protein-3 (NLRP3) inflammasome and decreases renal tubular epithelial-to-macrophage crosstalk in a model of diabetic kidney disease

Cell Communication and Signaling
Background Accompanied by activation of the NOD-like receptor protein 3 (NLRP3) inflammasome, aberrant connexin 43 (Cx43) hemichannel-mediated ATP release is situated upstream of inflammasome assembly and inflammation and contributes to multiple ...

The Role of Connexin and Pannexin Channels in Perinatal Brain Injury and Inflammation

Frontiers in Physiology, 2019
Perinatal brain injury remains a major cause of death and life-long disability. Perinatal brain injury is typically associated with hypoxia-ischemia and/or infection/inflammation.

Connexin 43 hemichannels and prostaglandin E2 release in anabolic function of the skeletal tissue to mechanical stimulation

Frontiers in Cell and Developmental Biology, 2023
Bone adapts to changes in the physical environment by modulating remodeling through bone resorption and formation to maintain optimal bone mass. As the most abundant connexin subtype in bone tissue, connexin 43 (Cx43)-forming hemichannels are highly ...

Astrocytic connexin43 phosphorylation contributes to seizure susceptibility after mild traumatic brain injury

The FEBS Journal, EarlyView.
Astrocytic gap junctions formed by connexin43 (Cx43) help maintain brain homeostasis. After mild traumatic brain injury (TBI), total cortical Cx43 increases and redistributes toward a soluble, non‐junctional pool with elevated hemichannel activity and increased phosphorylation at serine 368 (pCx43S368).

Regulation of Connexin Hemichannels by Monovalent Cations [PDF]

The Journal of General Physiology, 2005
Opening of connexin hemichannels in the plasma membrane is highly regulated. Generally, depolarization and reduced extracellular Ca2+ promote hemichannel opening. Here we show that hemichannels formed of Cx50, a principal lens connexin, exhibit a novel form of regulation characterized by extraordinary sensitivity to extracellular monovalent cations ...

Analysis of Hemichannels and Gap Junctions: Application and Extension of the Passive Transmembrane Ion Transport Model

Frontiers in Cellular Neuroscience, 2021
Electrical synaptic transmission is an essential form of interneuronal communication which is mediated by gap junctions that permit ion flow. Three gene families (connexins, innexins, and pannexins) have evolved to form gap junctional channels.

Changes in motor unit conduction velocity after unilateral lower‐limb suspension and active recovery are correlated with muscle ion channel gene expression

Experimental Physiology, EarlyView.
Abstract The effects of muscle disuse on the propagation of action potentials along motor unit (MU) muscle fibres, a key process for effective muscle activation and force generation, remain poorly understood. The aim of this study was to investigate changes in action potential propagation and to identify biological factors influencing these changes ...

Induction of Connexin-hemichannel Opening

, 2014
Connexins (Cxs) are integral membrane proteins of vertebrates that associate to form hexameric transmembrane channels, named hemichannels. Twenty-one Cx types have been described, which are named according to their molecular weight.

Advanced imaging and multi‐omics to characterize cardiomyocyte ageing and its electrocardiographic imprint in PKP2 arrhythmogenic cardiomyopathy

The Journal of Physiology, EarlyView.
Abstract figure legend We used a murine model of cardiomyocyte‐specific conditional knockout of plakophilin 2 (PKP2cKO, middle panel). Using advanced imaging technology, we unveiled distinct hallmarks of premature ageing in PKP2cKO cardiomyocytes, including DNA damage and loss of repressed heterochromatin at the nuclear periphery, and mitochondrial ...

The Role of Connexin 43 and Pannexin 1 During Acute Inflammation

Frontiers in Physiology, 2020
During acute inflammation, the recruitment of leukocytes from the blood stream into the inflamed tissue is a well-described mechanism encompassing the interaction of endothelial cells with leukocytes allowing leukocytes to reach the site of tissue injury
