Review Article
Endokanabinoidní systém má širokou škálu účinků v CNS i v periferních tkáních. Systém tvoří kanabinoidní receptory CB1 a CB2, endokanabinoidy a jejich biosyntetické a degradační enzymy. CB1 receptory se ve velké hustotě nacházejí na presynaptických zakončeních neuronů v mozku, kde ovlivňují přenos nervového vzruchu. Mají vliv na vnímání bolesti, tlumení stresové reakce, řízení motorických funkcí, kognici, emocionální reakce, regulaci příjmu potravy, psychickou homeostázu a motivaci. CB1 receptory jsou dále přítomny v buňkách zažívacího traktu, jaterních buňkách, buňkách bílé a hnědé tukové tkáně, buňkách Langerhansových ostrůvků slinivky břišní. V těchto periferních tkáních je jejich úkolem zachování energetické rovnováhy.
Overview
Endocannabinoid system has a wide scale of actions on CNS and on peripheral tissues. The system consists of cannabinoid receptors CB1 and CB2, endocannabinoids and their biosynthetic and degrading enzymes. CB1 receptors in high density occur on presynaptic neuronal terminals in brain influencing neurotransmission thereby number of functions – pain perception, inhibition of stress reaction, regulation of motor functions, cognition, emotional reactions, regulation of food intake, psychical homeostasis and motivation. CB1 receptors are present in GIT cells, hepatocytes, adipocytes, pancreatic isles cells. Energy homeostasis is the main function in peripheral issues. CB2 receptors are present mainly in cells of immune system, in the cilliary body of eye, in testes, vasal cells, and intestinal smooth muscle cells.
Key words:
endocannabinoids, endocannabinoid system, regulation of food intake, immunity, metabolic syndrome.
