The aim of the present study is to examine the relationship between preference for HFD and 2-arachidonoylglycerol (2-AG), endogenous cannabinoid. The 3-day HFD intake induced preference for HFD, which was suppressed by CB1 antagonist, O-2050. Moreover, hypothalamic 2-AG was increased after 3-day HFD intake. Our results show that preference for HFD is(More)
BACKGROUND In this study, we examined alterations in the hypothalamic reward system related to high-fat diet (HFD) preferences. We previously reported that hypothalamic 2-arachidonoylglycerol (2-AG) and glial fibrillary acid protein (GFAP) were increased after conditioning to the rewarding properties of a HFD. Here, we hypothesized that increased 2-AG(More)
Endocannabinoids have been shown to activate reward-related feeding and to promote astrocytic differentiation. We investigated whether high-fat diet (HFD) intake produced a preference for HFD via an endocannabinoid-dependent mechanism. In the conditioned place preference test, the 2-week HFD-intake group showed preference for HFD and had increased(More)
Endocannabinoid 2-arachidonoylglycerol (2-AG) regulates several important physiological processes in the brain. 2-AG is commonly quantified by gas chromatography mass spectrometry after an initial purification step. The most precise and rapid purification utilizes C(18) solid-phase extraction, but quantification problems can arise with acyl migration from(More)
