International union of pharmacology. XXIV. Current status of the nomenclature and properties of P2X receptors and their subunits

…, C Kennedy, BF King, RA North, P Séguéla… - Pharmacological …, 2001 - ASPET
ATP acts as a humoral mediator to control cell function extracellularly. The receptors that
mediate the actions of ATP belong to two classes, the metabotropic P2Y receptors and the …

An N-terminal variant of Trpv1 channel is required for osmosensory transduction

RS Naeini, MF Witty, P Séguéla, CW Bourque - Nature neuroscience, 2006 - nature.com
Body fluid homeostasis requires the release of arginine-vasopressin (AVP, an antidiuretic
hormone) from the neurohypophysis. This release is controlled by specific and highly sensitive …

Central P2X4 and P2X6 channel subunits coassemble into a novel heteromeric ATP receptor

KT Lê, K Babinski, P Séguéla - Journal of Neuroscience, 1998 - Soc Neuroscience
Ionotropic ATP receptors are widely expressed in mammalian CNS. Despite extensive
functional characterization of neuronal homomeric P2X receptors in heterologous expression …

Downregulation of tonic GABAergic inhibition in a mouse model of fragile X syndrome

G Curia, T Papouin, P Séguéla, M Avoli - Cerebral cortex, 2009 - academic.oup.com
The absence of fragile X mental retardation protein results in the fragile X syndrome (FXS),
a common form of mental retardation associated with attention deficit, autistic behavior, and …

P2X receptor channels in chronic pain pathways

LP Bernier, AR Ase, P Séguéla - British journal of …, 2018 - Wiley Online Library
Chronic pain is a highly prevalent debilitating condition for which treatment options remain
limited for many patients. Ionotropic ATP signalling through excitatory and calcium‐…

[HTML][HTML] A protein kinase C site highly conserved in P2X subunits controls the desensitization kinetics of P2X2 ATP-gated channels

E Boué-Grabot, V Archambault, P Séguéla - Journal of Biological Chemistry, 2000 - ASBMB
P2X receptors are nonselective cation channels gated by extracellular ATP. Recombinant
mammalian P2X subunits assemble in homomeric ionotropic ATP receptors that differ by their …

Molecular cloning and regional distribution of a human proton receptor subunit with biphasic functional properties

K Babinski, KT Lê, P Séguéla - Journal of neurochemistry, 1999 - Wiley Online Library
: Small changes of extracellular pH activate depolarizing inward currents in most nociceptive
neurons. It has been recently proposed that acid sensitivity of sensory as well as central …

P2Y12 expression and function in alternatively activated human microglia

…, O Butovsky, SK Ludwin, P Séguéla… - Neuroimmunology & …, 2015 - AAN Enterprises
Objective: To investigate and measure the functional significance of altered P2Y12 expression
in the context of human microglia activation. Methods: We performed in vitro and in situ …

Remote optogenetic activation and sensitization of pain pathways in freely moving mice

…, A Ribeiro-da-Silva, JS Mogil, P Séguéla - Journal of …, 2013 - Soc Neuroscience
We report a novel model in which remote activation of peripheral nociceptive pathways in
transgenic mice is achieved optogenetically, without any external noxious stimulus or injury. …

ADP and AMP induce interleukin-1β release from microglial cells through activation of ATP-primed P2X7 receptor channels

…, D Malo, D Henderson, P Seguela - Journal of …, 2002 - Soc Neuroscience
P2X 7 is a subtype of ATP-gated channels that is highly expressed in astrocytes, microglia,
and other immune cells. Activation of P2X 7 purinoceptors by ATP or 3′-O-(4-benzoyl)-…
