Abstract

BACKGROUND: Studies in animals indicate that brown adipose tissue is important in the regulation of body weight, and it is possible that individual variation in adaptive thermogenesis can be attributed to variations in the amount or activity of brown adipose tissue. Until recently, the presence of brown adipose tissue was thought to be relevant only in small mammals and infants, with negligible physiologic relevance in adult humans. We performed a systematic examination of the presence, distribution, and activity of brown adipose tissue in lean and obese men during exposure to cold temperature. Brown-adipose-tissue activity was studied in relation to body composition and energy metabolism. METHODS: We studied 24 healthy men--10 who were lean (body-mass index [BMI] [the weight in kilograms divided by the square of the height in meters], < 25) and 14 who were overweight or obese (BMI, > or = 25)--under thermoneutral conditions (22 degrees C) and during mild cold exposure (16 degrees C). Putative brown-adipose-tissue activity was determined with the use of integrated (18)F-fluorodeoxyglucose positron-emission tomography and computed tomography. Body composition and energy expenditure were measured with the use of dual-energy x-ray absorptiometry and indirect calorimetry. RESULTS: Brown-adipose-tissue activity was observed in 23 of the 24 subjects (96%) during cold exposure but not under thermoneutral conditions. The activity was significantly lower in the overweight or obese subjects than in the lean subjects (P=0.007). BMI and percentage of body fat both had significant negative correlations with brown adipose tissue, whereas resting metabolic rate had a significant positive correlation. CONCLUSIONS: The percentage of young men with brown adipose tissue is high, but its activity is reduced in men who are overweight or obese. Brown adipose tissue may be metabolically important in men, and the fact that it is reduced yet present in most overweight or obese subjects may make it a target for the treatment of obesity.

  • All groups showed major depots of metabolically active fat in the cervical-supraclavicular region, a slightly different site from that in rodents and children, where BAT is found mainly in the interscapular area.

  • In 2009, five independent groups used PET-CT to identify the presence and study the relevance of BAT in adult humans.

    “However, the real breakthrough arrived in 2009 when five independent groups used PET-CT to identify the presence and study the relevance of BAT in adult humans ([30](#B30), [143](#B143), [165](#B165), [168](#B168), [181](#B181)).”

  • Expression of UCP1, DIO2, and the β3-adrenergic receptor was reported, indicating the potential responsiveness of human BAT to both hormonal and pharmacological stimuli.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
