title: Increment of hypothalamic 2-arachidonoylglycerol induces the preference for a high-fat diet via activation of cannabinoid 1 receptors.
abstract: 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 induced by activation of CB1 receptors via an increment of 2-AG in hypothalamus.
