The emerging Pannexin 1 signalome: a new nexus revealed?

open access: yesFrontiers in Cellular Neuroscience, 2014
Pannexins (Panxs) are a family of single-membrane, large-pore ion and metabolite permeable channels. Of the three Panx proteins, Panx1 has been most extensively studied, and has recently emerged as an exciting, clinically relevant target in many ...

Pannexin-1 Channels as Mediators of Neuroinflammation [PDF]

open access: yesInternational Journal of Molecular Sciences, 2021
Neuroinflammation is a major component of central nervous system (CNS) injuries and neurological diseases, including Alzheimer’s disease, multiple sclerosis, neuropathic pain, and brain trauma. The activation of innate immune cells at the damage site causes the release of pro-inflammatory cytokines and chemokines, which alter the functionality of ...

Pannexin channels and ischaemia [PDF]

open access: yesThe Journal of Physiology, 2014
AbstractAn ischaemic stroke occurs during loss of blood flow in the brain from the occlusion of a blood vessel. The ischaemia itself comprises a complex array of insults, including oxygen and glucose deprivation (OGD), glutamate excitotoxicity, acidification/hypercapnia, and loss of sheer forces.

Pannexins in ischemia-induced neurodegeneration [PDF]

open access: yesProceedings of the National Academy of Sciences, 2011
Pannexin 1 (Px1, Panx1) and pannexin 2 (Px2, Panx2) form large-pore nonselective channels in the plasma membrane of cells and were suggested to play a role in the pathophysiology of cerebral ischemia. To directly test a potential contribution of pannexins in ischemia-related mechanisms, we performed experiments in

Pannexin 1 and Pannexin 3 Channels Regulate Skeletal Muscle Myoblast Proliferation and Differentiation [PDF]

open access: yesJournal of Biological Chemistry, 2014
Pannexins constitute a family of three glycoproteins (Panx1, -2, and -3) forming single membrane channels. Recent work demonstrated that Panx1 is expressed in skeletal muscle and involved in the potentiation of contraction. However, Panxs functions in skeletal muscle cell differentiation, and proliferation had yet to be assessed.

Pannexins Are Potential New Players in the Regulation of Cerebral Homeostasis during Sleep-Wake Cycle

open access: yesFrontiers in Cellular Neuroscience, 2017
During brain homeostasis, both neurons and astroglia release ATP that is rapidly converted to adenosine in the extracellular space. Pannexin-1 (Panx1) hemichannels represent a major conduit of non-vesicular ATP release from brain cells.

Expression of connexins and pannexins in diseased human liver

open access: yesEXCLI Journal : Experimental and Clinical Sciences, 2022
Connexin proteins can form hexameric hemichannels and gap junctions that mediate paracrine and direct intercellular communication, respectively. Gap junction activity is crucial for the maintenance of hepatic homeostasis, while connexin hemichannels ...

Prenatal nicotine exposure enhances Cx43 and Panx1 unopposed channel activity in brain cells of adult offspring mice fed a high-fat/cholesterol diet

open access: yesFrontiers in Cellular Neuroscience, 2014
Nicotine, the most important neuroteratogen of tobacco smoke, can reproduce brain and cognitive disturbances per se when administered prenatally. However, it is still unknown if paracrine signaling among brain cells participates in prenatal nicotine ...

Control of the neurovascular coupling by nitric oxide-dependent regulation of astrocytic Ca2+ signaling

open access: yesFrontiers in Cellular Neuroscience, 2015
Neuronal activity must be tightly coordinated with blood flow to keep proper brain function, which is achieved by a mechanism known as neurovascular coupling. Then, an increase in synaptic activity leads to a dilation of local parenchymal arterioles that

Panx1 channels promote both anti- and pro-seizure-like activities in the zebrafish via p2rx7 receptors and ATP signaling

open access: yesCommunications Biology, 2022
The Panx1a and Panx1b (pannexin) ATP release channels exhibit pro- and anti-convulsant effects, respectively, in a zebrafish model, providing further insight into the role of pannexins in seizure development.
