Cx46 hemichannel modulation by nitric oxide: Role of the fourth transmembrane helix cysteine and its possible involvement in cataract formation

Under normal conditions, connexin (Cx) hemichannels have a low open probability, which can increase under pathological conditions. Since hemichannels are permeable to relatively large molecules, their exacerbated activity has been linked to cell dama

Permeation of Calcium through Purified Connexin 26 Hemichannels

Autor: Maria E. Zoghbi, Guillermo A. Altenberg, Vania Figueroa, Mariana C. Fiori, Juan C. Sáez, Luis Reuss

Publikováno v: Journal of Biological Chemistry. 287:40826-40834

Indirect evidence suggests that connexin hemichannels are permeable to Ca(2+), but direct demonstration is lacking.Calcium moves into liposomes containing purified Cx26 in response to a concentration gradient.Cx26 hemichannels are permeable to Ca(2+)

Biphasic effect of linoleic acid on connexin 46 hemichannels

Autor: Carmen G. León-Paravic, Flavio Evangelista-Martínez, Mauricio A. Retamal, Guillermo A. Altenberg, Luis Reuss

Publikováno v: Pflügers Archiv - European Journal of Physiology. 461:635-643

Connexins form hemichannels at undocked plasma membranes and gap-junction channels (GJCs) at intercellular contacting zones. Under physiological conditions, hemichannels have low open probabilities, but their activation under pathological conditions,

Gap-junction hemichannels are composed of six protein subunits (connexins). Undocked hemichannels contribute to physiological autocrine/paracrine cell signaling, including release of signaling molecules, cell-volume regulation, and glucose uptake. In

Functional hemichannels formed by human connexin 26 expressed in bacteria

Bioscience Reports

Gap-junction channels (GJCs) communicate the cytoplasm of adjacent cells and are formed by head-to-head association of two hemichannels (HCs), one from each of the neighbouring cells. GJCs mediate electrical and chemical communication between cells,

Mutations of connexin 26 at position 75 and dominant deafness: Essential role of arginine for the generation of functional gap-junctional channels

Autor: Luis Reuss, Yanqin Deng, Yongyue Chen, Guillermo A. Altenberg

Publikováno v: Hearing Research. 220:87-94

Gap-junctional channels are large intercellular aqueous pores formed by head-to-head association of two gap-junctional hemichannels (connexin hexamers), one from each of the adjacent cells. The mechano-transduction of sound waves into electrical impu

Marked increase in cell permeability ascribed to open connexin (Cx)43 hemichannels is induced by metabolic inhibition (MI) of cortical astrocytes in culture, but the molecular mechanisms are not established. Dephosphorylation and/or oxidation of Cx43
