Effect of ghrelin receptor agonist and antagonist on the activity of arcuate nucleus tyrosine hydroxylase containing neurons in C57BL/6 male mice exposed to normal or high fat diet

Popis výsledku v původním jazyce

Catecholamines participate in the food intake regulation, however, there are no literature data available, dealing with the activity of tyrosine hydroxylase (TH) neurons in response to stimulation or inhibition of GHS-R (growth hormone secretagogue receptor) in the hypothalamic arcuate nucleus (ARC). The present study was focused to reveal whether [Dpr(N-octanoyl)3ghrelin], a stable GHS-R agonist, itself in doses of 5 or 10 mg/kg (s.c.) or in combination with GHS-R receptor antagonist ([DLys3]GHRP-6) indose of 10 mg/kg (s.c.), may affect the activity of ARC TH-containing neurons in C57BL/6 male mice fed either with standard (SD) or high fat diet (HFD) that developed a diet-induced obesity (DIO). The data of the present study clearly indicate that bothdoses of GHS-R agonist stimulated food intake in SD mice and GHS-R antagonist significantly reduced GHS-R agonist orexinergic effect in SD mice and suppressed the voluntary food intake in HFD mice. Both doses of the GHS-R agonist stimula
