Description
  • The research of the glutamatergic system in schizophrenia has advanced with the use of non-competitive antagonists of glutamate NMDA receptors (phencyclidine, ketamine, and dizocilpine)., which change both human and animal behaviour and induce schizophreni-like manifestations. Models based on both acute and chronic administration of these substances in humans and rats show phenomenological validity and are suitable for searching for new substances with antipsychotic effects. Nevertheless, pathophysiology of schizophrenia remains unexplained. In the light of the neurodevelopmental model of schizophrenia based on early administration of NMDA receptor antagonists it seems that increased cellular destruction by apoptosis or changes in function of glutamatergic NMDA receptors in the early development of central nervous system are decisive for subsequent development of psychosis, which often does not manifest itself until adulthood. Chronic administration of antagonists initializes a number of adaptation me

  • Výzkum glutamátergního systému u schizofrenie pokročil za použití nekompetitivních antagonistů glutamátergních NMDA receptorů (fencyklidin, ketamin a dizocilpin), které mění lidské i zvířecí chování a vyvolávají schizofrenii podobné projevy. Modely založené jak na akutním tak chronickém podávání těchto látek u lidí a u potkanů vykazují fenomenologickou validitu a jsou vhodné pro hledání nových látek s antipsychotickým účinkem. Nicméně, patofyziologie schizofrenie zůstává i nadále nevysvětlená. Při použití neurovývojového modelu schizofrenie založeného na časném podání antagonistů NMDA receptoru se zdá, že zvýšený zánik buněk apoptózou nebo změnami funkce glutamátergních NMDA receptorů v časném vývoji CNS je rozhodující pro následný rozvoj psychózy. Ta se však často projeví až v dospělosti. Chronické podávání antagonistů iniciuje řadu adaptačních mechanizmů, které korelují s nálezy získanými u schizofreniků; proto je tento model také vhodný for výzkum patofyziologie této nemoci. (cs)
