Connexin43 hemichannels contributes to the disassembly of cell junctions through modulation of intracellular oxidative status

open access: yesRedox Biology, 2016
Connexin (Cx) hemichannels regulate many cellular processes with little information available regarding their mechanisms. Given that many pathological factors that activate hemichannels also disrupts the integrity of cellular junctions, we speculated a ...

Large-pore connexin hemichannels function like molecule transporters independent of ion conduction

open access: yesProceedings of the National Academy of Sciences of the United States of America
Significance The mechanism behind molecule permeation through large-pore connexin hemichannels remains enigmatic. The current perspective posits that ions and molecules diffuse simultaneously, with molecule selectivity and permeability mainly relying on ...

Differential sensitivity of brainstem vs cortical astrocytes to changes in pH reveals functional regional specialization of astroglia [PDF]

open access: yes, 2013
Astrocytes might function as brain interoceptors capable of detecting different (chemo)sensory modalities and transmitting sensory information to the relevant neural networks controlling vital functions.

Gap junction proteins and their role in spinal cord injury [PDF]

open access: yes, 2015
© 2015 Tonkin, Mao, O'Carroll, Nicholson, Green, Gorrie and Moalem-Taylor. Gap junctions are specialized intercellular communication channels that are formed by two hexameric connexin hemichannels, one provided by each of the two adjacent cells.

Detecting CO2-Sensitive Hemichannels in Neurons in Acute Brain Slices

open access: yesSTAR Protocols, 2020
Summary: This protocol provides two independent methods to functionally detect the neuronal expression of CO2-sensitive hemichannels. These hemichannels (consisting of connexins 26 or 30) are directly gated by CO2, independent of pH changes and until ...

Osmotic Edema Rapidly Increases Neuronal Excitability Through Activation of NMDA Receptor-Dependent Slow Inward Currents in Juvenile and Adult Hippocampus. [PDF]

open access: yes, 2015
Cellular edema (cell swelling) is a principal component of numerous brain disorders including ischemia, cortical spreading depression, hyponatremia, and epilepsy.

Voltage-dependent facilitation of Cx46 hemichannels

open access: yesAmerican Journal of Physiology-Cell Physiology, 2010
Gap junction channels are formed by two hemichannels in series (one from each neighboring cell), which are in turn connexin hexamers. Under normal conditions, hemichannels at the plasma membrane are mostly closed but can be opened by changes in membrane voltage, extracellular divalent ion concentration, phosphorylation, pH, and redox potential ...

Nanomaterial‐based immune therapeutic strategies in neurodegenerative diseases

open access: yesBMEMat, EarlyView.
This review highlights the immunomodulatory potential of nanomaterials (NMs) in treating neurodegenerative diseases (NDs). It focuses on their roles in regulating innate and adaptive immune responses to maintain immune homeostasis. By providing insights into these mechanisms, the review lays the groundwork for innovative NMs therapeutic strategies to ...

Role of Pannexin-1 hemichannels and purinergic receptors in the pathogenesis of human diseases

open access: yesFrontiers in Physiology, 2014
In the last decade several groups have determined the key role of hemichannels formed by pannexins or connexins, extracellular ATP and purinergic receptors in physiological and pathological conditions.

Pathogenic connexin-31 forms constitutively active hemichannels to promote necrotic cell death. [PDF]

open access: yesPLoS ONE, 2012
Mutations in Connexin-31 (Cx31) are associated with multiple human diseases including erythrokeratodermia variabilis (EKV). The molecular action of Cx31 pathogenic mutants remains largely elusive.
