Brown adipose tissue (BAT) is a therapeutic target for obesity and associated metabolic diseases, due to its role in non-shivering thermogenesis. BAT activation is mediated through sympathetic stimulation, but parasympathetic regulation of human BAT has not been demonstrated previously. We undertook RNA sequencing of human white and brown primary adipocytes to identify novel pathways regulating BAT. CHRM2 (encoding the muscarinic acetylcholine receptor 2) was the most differen...

The recent discovery of brown adipose tissue (BAT) in adult humans, which generates heat to maintain body temperature in a cold environment, offers an exciting new strategy to treat obesity and metabolic disease, but our knowledge of human BAT activation is limited. To identify novel pathways regulating human BAT, we undertook RNA sequencing of human brown and white adipocytes. The gene SLC6A4 (encoding the serotonin transporter SERT) was one of the most highly differ...

Background: 18F-fluorodeoxyglucose (18FDG) PET is commonly used to quantify brown adipose tissue (BAT) mass/activity in humans but requires cold exposure. Rodent brown (BAds) but not white adipocytes (WAds) exhibit high choline content, thus we hypothesised that human BAT would demonstrate substantial 18F-fluorocholine (18FCH) uptake in vivo during warm and cold conditions.Methods: (1)...
