Gap junctions, pannexins and pain [PDF]
Neuroscience Letters, 2019 Enhanced expression and function of gap junctions and pannexin (Panx) channels have been associated with both peripheral and central mechanisms of pain sensitization. At the level of the sensory ganglia, evidence includes augmented gap junction and pannexin1 expression in glial cells and neurons in inflammatory and neuropathic pain models and increased

Pannexins in ischemia-induced neurodegeneration [PDF]
Proceedings 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

Perspectives on the role of Pannexin 1 in neural precursor cell biology
Neural Regeneration Research, 2016 We recently reported that targeted deletion of Pannexin 1 in neural precursor cells of the ventricular zone impairs the maintenance of these cells in healthy and stroke-injured brain. Here we frame this exciting new finding in the context of our previous

The Cryo-EM structure of pannexin 1 reveals unique motifs for ion selection and inhibition
eLife, 2020 Pannexins are large-pore forming channels responsible for ATP release under a variety of physiological and pathological conditions. Although predicted to share similar membrane topology with other large-pore forming proteins such as connexins, innexins ...

Pannexin 1 Modulates Axonal Growth in Mouse Peripheral Nerves
Frontiers in Cellular Neuroscience, 2017 The pannexin family of channels consists of three members—pannexin-1 (Panx1), pannexin-2 (Panx2), and pannexin-3 (Panx3) that enable the exchange of metabolites and signaling molecules between intracellular and extracellular compartments.

Pannexins in Acute Kidney Injury [PDF]
Nephron, 2019 Acute kidney injury (AKI) is highly prevalent among hospitalized patients and is associated with serious consequences with limited pharmacological treatment options. Pannexin 1 (Panx1) channel is a ubiquitously expressed nonselective membrane transport channel that efficiently effluxes ATP and plays a central role in the progression of inflammatory ...

Lymphatic Connexins and Pannexins in Health and Disease [PDF]
International Journal of Molecular Sciences, 2021 This review highlights current knowledge on the expression and function of connexins and pannexins, transmembrane channel proteins that play an important role in intercellular communication, in both the developing and mature lymphatic vasculature. A particular focus is given to the involvement of these proteins in functions of the healthy lymphatic ...

Pannexin channels and ischaemia [PDF]
The 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.

Role of astroglial hemichannels and pannexons in Memory and Neurodegenerative diseases
Frontiers in Integrative Neuroscience, 2016 Under physiological conditions, astroglial hemichannels and pannexin channels allow the release of gliotransmitters from astrocytes. These gliotransmitters are critical in modulating synaptic transmission, plasticity and memory.
