Principles and properties of ion flow in P2X receptors
P2X receptors are a family of trimeric ion channels that are gated by extracellular adenosine 5'-triphosphate (ATP). These receptors have long been a subject of intense research interest by virtue of their vital role in mediating the rapid and direct effects of extracellular ATP on membrane potential and cytosolic Ca(2+) concentration, which in turn underpin the ability of ATP to regulate a div...
متن کاملP2X receptors.
Extracellular adenosine 5'-triphosphate (ATP) activates cell surface P2X and P2Y receptors. P2X receptors are membrane ion channels preferably permeable to sodium, potassium and calcium that open within milliseconds of the binding of ATP. In molecular architecture, they form a unique structural family. The receptor is a trimer, the binding of ATP between subunits causes them to flex together wi...
متن کاملP2X receptors and nociception.
The potential importance for nociception of P2X receptors, the ionotropic receptors activated by ATP, is underscored by the variety of pain states in which this endogenous ligand can be released. Several important findings have been made recently indicating that P2X receptors can be involved in pain mechanisms both centrally and in the periphery. The roles of ATP at these two sites and the P2X ...

متن کاملP2X(7) receptors: properties and relevance to CNS function.
Among seven members of P2X ionotropic receptors activated by extracellular ATP, the P2X(7) subtype is unique in that it can function as a cation channel, a nonselective pore, or even a signaling complex coupled with multiple downstream components. Several roles of P2X(7) receptors have been described in CNS cells in the past decade, including release of cytokines and transmitters, modulation of...
