Extracellular ATP hydrolysis inhibits synaptic transmission by increasing ph buffering in the synaptic cleft. [PDF]
PLoS Biology, 2014 Neuronal computations strongly depend on inhibitory interactions. One such example occurs at the first retinal synapse, where horizontal cells inhibit photoreceptors.

Structural order in Pannexin 1 cytoplasmic domains [PDF]
Channels, 2014 Pannexin 1 forms ion and metabolite permeable hexameric channels with abundant expression in the central nervous system and elsewhere. Although pannexin 1 does not form intercellular channels, a common channel topology and oligomerization state, as well as involvement of the intracellular carboxyl terminal (CT) domain in channel gating, is shared with ...

Pannexin 1 in erythrocytes: Function without a gap [PDF]
Proceedings of the National Academy of Sciences, 2006 ATP is a widely used extracellular signaling molecule. The mechanism of ATP release from cells is presently unresolved and may be either vesicular or channel-mediated. Erythrocytes release ATP in response to low oxygen or to shear stress. In the absence of vesicles, the release has to be through channels. Erythrocytes do not form gap junctions.

Frontiers in Molecular Neuroscience, 2017 Background: Accumulating evidence suggests that neuroinflammation plays a critical role in early brain injury after subarachnoid hemorrhage (SAH). Pannexin-1 channels, as a member of gap junction proteins located on the plasma membrane, releases ATP ...

Epilepsia, EarlyView.Abstract Over the last 34 years, the Eilat Conference on New Antiepileptic Drugs and Devices has provided an interactive forum for stakeholders to discuss investigational and recently licensed treatments for seizures and epilepsy. The Eighteenth Eilat Conference on New Antiepileptic Drugs and Devices (EILAT XVIII) took place in Madrid, Spain, on May 3 ...

Pharmacologic inhibition by spironolactone attenuates experimental abdominal aortic aneurysms
Frontiers in Cardiovascular Medicine, 2023 BackgroundAbdominal aortic aneurysms (AAA) are characterized by vascular inflammation and remodeling that can lead to aortic rupture resulting in significant mortality. Pannexin-1 channels on endothelial cells (ECs) can modulate ATP secretion to regulate

The FEBS Journal, EarlyView.Astrocytic gap junctions formed by connexin43 (Cx43) help maintain brain homeostasis. After mild traumatic brain injury (TBI), total cortical Cx43 increases and redistributes toward a soluble, non‐junctional pool with elevated hemichannel activity and increased phosphorylation at serine 368 (pCx43S368).

Periodontitis as a Model for Inflammatory Uncoupling of Bone Remodeling
Journal of Periodontal Research, EarlyView.Periodontitis can be viewed as a state of inflammatory uncoupling of bone remodeling, in which excessive osteoclast‐mediated resorption coexists with impaired bone formation. This review integrates emerging insights from osteoimmunology, osteocyte biology, mechanobiology, aging, and resolution pathways to position periodontitis as an accessible in vivo
