This study investigates cannabinoid CB1 receptors in human brown adipose tissue (BAT) and
other tissues using positron emission tomography (PET) imaging. Subjects will be scanned in
room temperature conditions and during controlled cold exposure, and the density of CB1
receptors in BAT and other tissues will be quantified. The investigators hypothesize, that
cannabinoid signaling is increased in cold conditions, when BAT is metabolically active.
Understanding the mechanisms of BAT activation and the role of endocannabinoids in humans is
important and beneficial in fighting against the epidemic of obesity and diabetes.
