P2X7 receptor: an emerging target in central nervous system diseases

Sperlágh, Beáta, Illes, Peter·2014·Trends in Pharmacological Sciences

Abstract

The ATP-sensitive homomeric P2X7 receptor (P2X7R) has received particular attention as a potential drug target because of its widespread involvement in inflammatory diseases as a key regulatory element of the inflammasome complex. However, it has only recently become evident that P2X7Rs also play a pivotal role in central nervous system (CNS) pathology. There is an explosion of data indicating that genetic deletion and pharmacological blockade of P2X7Rs alter responsiveness in animal models of neurological disorders, such as stroke, neurotrauma, epilepsy, neuropathic pain, multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), Alzheimer's disease, Parkinson's disease, and Huntington's disease. Moreover, recent studies suggest that P2X7Rs regulate the pathophysiology of psychiatric disorders, including mood disorders, implicating P2X7Rs as drug targets in a variety of CNS pathology.

  • Activation of P2X7 receptors induced by viral infection leads to molecular alterations (neuroimmune response activation, ROS formation, and glutamate release), behavioral alterations, and mental disorders.

    “their activation induced by viral infection leads to molecular (mainly neuroimmune response activation, reactive oxygen species (ROS) formation, and glutamate release) and behavioral alterations [17, 20] as well as to mental disorders [21].”
  • P2X7 receptor activation increases neuroinflammatory responses, which have been associated with neurodegenerative diseases, psychiatric disorders and stroke.

    “Remarkably, P2X7 receptor activation increases neuroinflammatory responses, which have been associated with neurodegenerative diseases, psychiatric disorders and stroke [21, 92–95], as further discussed.”
  • Purinergic signaling is involved in several psychiatric disorders, including MDD.

    “Purinergic signaling is involved in several psychiatric disorders, including MDD [25,26,27,28], and is mediated by nucleoside and nucleotide actions on P1 (P1R) and P2 (P2R) receptors.”

  • P2X7R-mediated effects, mainly through activation of the neuroinflammatory response, have been involved in MDD, neurodegenerative diseases, schizophrenia, epilepsy, neuropathic pain, and brain injury.

    “P2X7R-mediated effects, which mainly occurs through activation of the neuroinflammatory response, have been involved in MDD, neurodegenerative diseases, schizophrenia, epilepsy, neuropathic pain and brain injury [28,66,67,68].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
