Induction of Connexin-hemichannel Opening

open access: yesBio-Protocol, 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.

Connexin-based gap junction hemichannels: Gating mechanisms [PDF]

open access: yes, 2005
Connexins (Cxs) form hemichannels and gap junction channels. Each gap junction channel is composed of two hemichannels, also termed connexons, one from each of the coupled cells.

Connexin 43 Channels in Osteocytes Regulate Bone Responses to Mechanical Unloading

open access: yesFrontiers in Physiology, 2020
Connexin (Cx) 43 forms gap junctions and hemichannels that mediate communication between osteocytes and adjacent cells or the extracellular environment in bone, respectively.

The role of pannexin hemichannels in inflammation and regeneration [PDF]

open access: yesFrontiers in Physiology, 2014
Tissue injury involves coordinated systemic responses including inflammatory response, targeted cell migration, cell-cell communication, stem cell activation and proliferation, and tissue inflammation and regeneration. The inflammatory response is an important prerequisite for regeneration.

Pitfalls when examining gap junction hemichannels: interference from volume-regulated anion channels [PDF]

open access: yes, 2006
Human HeLa cells transfected with mouse connexin45 were used to explore the experimental conditions suitable to measure currents carried by gap junction hemichannels.

Connexin 43 Hemichannels Are Permeable to ATP [PDF]

open access: yesThe Journal of Neuroscience, 2008
Astrocytes are electrically nonexcitable cells that communicate by means of Ca2+signaling. Long-distance intercellular Ca2+waves are initiated by release of ATP and activation of purinergic receptors on nearby cells. Previous studies have implicated connexin 43 (Cx43) in ATP release, but definitive proof that ATP exits through Cx43 hemichannels does ...

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 ...

Characterization of Nonjunctional Hemichannels in Caterpillar Cells [PDF]

open access: yesJournal of Insect Science, 2011
Recent studies have demonstrated that hemichannels, which form gap junctions when paired from apposing cells, may serve additional roles when unpaired including cell adhesion and paracrine communication. Hemichannels in mammals are formed by connexins or pannexins, while in insects they are formed by pannexin homologues termed innexins.

Mechanosensitivity of gap junction hemichannels

open access: yes, 2005
Most gap junction hemichannels stay in the closed state before they dock to each other and form complete functional channels. Some exceptions, Connexin 46 (Cx46), Cx50 and pannexin 1, can form functional hemichannels in nonjunctional membranes.

Regulation of Cx45 hemichannels mediated by extracellular and intracellular calcium [PDF]

open access: yes, 2012
Connexin45 (Cx45) hemichannels (HCs) open in the absence of Ca(2+) and close in its presence. To elucidate the underlying mechanisms, we examined the role of extra- and intracellular Ca(2+) on the electrical properties of HCs.
