P2Y 12 is a chemoreceptor for adenosine diphosphate (ADP) [5] [6] that belongs to the G i class of a group of G protein-coupled (GPCR) purinergic receptors. [7] This P2Y receptor family has several receptor subtypes with different pharmacological selectivity, which overlaps in some cases, for various adenosine and uridine nucleotides .
P2Y 12 structure as generated by PYMOL with color-coded helices. P2Y receptors are membrane proteins belonging to the class A family of G protein-coupled receptors (GPCRs). [5] [6] P2Y receptor proteins display large-scale structural domains typical of GPCRs, consisting of seven hydrophobic transmembrane helices connected by three short extracellular loops and three variably sized ...
Microglial processes specifically recognize these purinergic somatic-junctions, and monitor neuronal functions by sensing purine nucleotides via their P2Y12-receptors. In case of neuronal overactivation or injury, microglial processes respond with an increased coverage of neuronal cell bodies, and exert robust neuroprotective effects. [ 38 ]

Cangrelor and ticagrelor are new classes of reversible P2Y 12 receptors that have been developed to target the issues of safety (bleeding) and non-responders which the thienopyridines have. Natural ligands like adenosine triphosphate ( ATP ) were shown to inhibit platelet aggregation and has been identified as a weak antagonist .
A branch of physics that studies atoms as isolated systems of electrons and an atomic nucleus. Compare nuclear physics. atomic structure atomic weight (A) The sum total of protons (or electrons) and neutrons within an atom. audio frequency A periodic vibration whose frequency is in the band audible to the average human, the human hearing range.
In physics, there are equations in every field to relate physical quantities to each other and perform calculations. Entire handbooks of equations can only summarize most of the full subject, else are highly specialized within a certain field. Physics is derived of formulae only.
