Abstract

Classically, adult humans have been considered not to possess active brown adipose tissue (BAT). However, positron‐emission‐tomography has shown fluorodeoxyglucose uptake that is distributed in such a way ( e.g. , in the neck) that it would seem to be BAT. Until now this has not been supported by direct evidence that these areas truly represented BAT, that is, the presence of the BAT‐unique uncoupling protein‐1 (UCP1). Samples of adipose tissue from the neck of 35 patients undergoing surgery for thyroid diseases were obtained and analyzed. In 1/3 of the subjects (the younger and leaner), distinct islands composed of UCP1 immunoreactive brown adipocytes could clearly be discerned, accounting for up to 1/3 of all adipocytes. The brown‐adipose islands were richlysympathetically innervated (indicating acute central control); adjacent white adipose areas were not. The capillary density was high, implying a high capacity for oxygen delivery. Cells with features of brown adipocyte precursors were found in pericapillary areas. These data demonstrate that human adults indeed possess BAT and thus imply possibilities of future therapeutic strategies for the treatment of obesity, including maintenance of brown adipocytes and stimulation of the growth of preexisting brown precursors.—Zingaretti, M.

  • Recent studies have shown that adult humans maintain potentially active brown adipose tissue, making this high energetic tissue a real therapeutic target.

    “Second, recent studies have shown that adult humans maintain potentially active brown adipose tissue, making this high energetic tissue a real therapeutic target 13–17.”

  • PET/CT imaging was used to prove conclusively that adult humans possess physiologically active UCP1-positive BAT.

    “However, it was only during the past year PET/CT imaging was used to prove conclusively that adult humans possess physiologically active UCP1-positive BAT,13–17.”

  • Given the scanning data and the finding of brown adipocyte precursors in human tissues, it is likely that virtually every adult human has the capacity to develop some functional BAT.

    “Given the scanning data and the finding of brown adipocyte precursors in human tissues 17, it is likely that virtually every adult human has the capacity to develop some functional BAT.”

  • Histological analysis of cervical fat biopsies show rates three times higher than retrospective PET/CT reports.

    “However, histological analysis of cervical fat biopsies show rates three times higher 17, and prospective studies using cold stimulation to increase BAT activity and detection via PET/CT show that among younger people, 96% have functional BAT 14.”

  • Adult human BAT is functional and may be involved in protecting against weight loss.

    “Although it has only recently been proven that adult human BAT is functional and may be involved in protecting against weight loss 13–17, attempts to exploit BAT energy expenditure for treating obesity have been around for decades.”

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.
