Connexin and Pannexin-Based Channels in Oligodendrocytes: Implications in Brain Health and Disease.

Frontiers in cellular neuroscience

Vejar S, Oyarzún JE, Retamal MA, Ortiz FC, Orellana JA.
PMID: 30760982
Front Cell Neurosci. 2019 Jan 29;13:3. doi: 10.3389/fncel.2019.00003. eCollection 2019.

Oligodendrocytes are the myelin forming cells in the central nervous system (CNS). In addition to this main physiological function, these cells play key roles by providing energy substrates to neurons as well as information required to sustain proper synaptic...

Diseases associated with leaky hemichannels.

Frontiers in cellular neuroscience

Retamal MA, Reyes EP, García IE, Pinto B, Martínez AD, González C.
PMID: 26283912
Front Cell Neurosci. 2015 Jul 27;9:267. doi: 10.3389/fncel.2015.00267. eCollection 2015.

Hemichannels (HCs) and gap junction channels (GJCs) formed by protein subunits called connexins (Cxs) are major pathways for intercellular communication. While HCs connect the intracellular compartment with the extracellular milieu, GJCs allow the interchange of molecules between cytoplasm of...

Vitamin C and Microvascular Dysfunction in Systemic Inflammation.

Tyml K.
PMID: 28661424
Antioxidants (Basel). 2017 Jun 29;6(3). doi: 10.3390/antiox6030049.

Sepsis, life-threatening organ dysfunction caused by a dysfunctional host response to infection, is associated with high mortality. A promising strategy to improve the outcome is to inject patients intravenously with ascorbate (vitamin C). In animal models of sepsis, this...

Managing the complexity of communication: regulation of gap junctions by post-translational modification.

Frontiers in pharmacology

Axelsen LN, Calloe K, Holstein-Rathlou NH, Nielsen MS.
PMID: 24155720
Front Pharmacol. 2013 Oct 22;4:130. doi: 10.3389/fphar.2013.00130.

Gap junctions are comprised of connexins that form cell-to-cell channels which couple neighboring cells to accommodate the exchange of information. The need for communication does, however, change over time and therefore must be tightly controlled. Although the regulation of...

Connexins and Nitric Oxide Inside and Outside Mitochondria: Significance for Cardiac Protection and Adaptation.

Frontiers in physiology

Shvedova M, Anfinogenova Y, Popov SV, Atochin DN.
PMID: 29867537
Front Physiol. 2018 May 16;9:479. doi: 10.3389/fphys.2018.00479. eCollection 2018.

Irreversible myocardial damage happens in the presence of prolonged and severe ischemia. Several phenomena protect the heart against myocardial infarction and other adverse outcomes of ischemia and reperfusion (IR), namely: hibernation related to stunned myocardium, ischemic preconditioning (IPC), ischemic...

Bioelectrical signals improve cardiac function and modify gene expression of extracellular matrix components.

ESC heart failure

Macfelda K, Kapeller B, Holly A, Podesser BK, Losert U, Brandes K, Goettel P, Mueller J.
PMID: 28772035
ESC Heart Fail. 2017 Aug;4(3):291-300. doi: 10.1002/ehf2.12169. Epub 2017 Jun 30.

AIMS: Beyond the influence of stimulating devices on cardiac excitation, their use in treating patients with heart failure has positive effects on the myocardium at the molecular level. Electrical signals can induce a wide spectrum of effects in living...

Efficacy of THN201, a Combination of Donepezil and Mefloquine, to Reverse Neurocognitive Deficits in Alzheimer's Disease.

Frontiers in neuroscience

Droguerre M, Duchêne A, Picoli C, Portal B, Lejards C, Guiard BP, Meunier J, Villard V, Déglon N, Hamon M, Mouthon F, Charvériat M.
PMID: 32612499
Front Neurosci. 2020 Jun 16;14:563. doi: 10.3389/fnins.2020.00563. eCollection 2020.

Donepezil (DPZ) is an acetylcholinesterase inhibitor used in Alzheimer's disease to restore cognitive functions but is endowed with limited efficacy. Recent studies pointed out the implication of astroglial networks in cognitive processes, notably via astrocyte connexins (Cxs), proteins involved...

Heavy Alcohol Exposure Activates Astroglial Hemichannels and Pannexons in the Hippocampus of Adolescent Rats: Effects on Neuroinflammation and Astrocyte Arborization.

Frontiers in cellular neuroscience

Gómez GI, Falcon RV, Maturana CJ, Labra VC, Salgado N, Rojas CA, Oyarzun JE, Cerpa W, Quintanilla RA, Orellana JA.
PMID: 30564103
Front Cell Neurosci. 2018 Dec 04;12:472. doi: 10.3389/fncel.2018.00472. eCollection 2018.

A mounting body of evidence indicates that adolescents are specially more susceptible to alcohol influence than adults. However, the mechanisms underlying this phenomenon remain poorly understood. Astrocyte-mediated gliotransmission is crucial for hippocampal plasticity and recently, the opening of hemichannels...

ABSTRACT: Tricyclic antidepressants that inhibit serotonin and noradrenaline reuptake, such as amitriptyline, are among the first-line treatments for neuropathic pain, which is caused by a lesion or disease affecting the somatosensory nervous system. These treatments are, however, partially efficient...
