Both groups had similar age, sex distribution, body mass index, and classical cardiovascular risk profile. However, BAT-positive individuals had significantly less arterial inflammation as evidenced by lower\n                      <jats:sup>18<\/jats:sup>\n                      F-fluorodeoxyglucose uptake in the ascending aorta and the aortic arch.

Using unbiased lipidomics and proteomics analyses in plasma, we found that anti-inflammatory and potentially antiatherogenic circulating factors, such as cytochrome P450 oxylipin products and the serpin family member SERPINB12 (serpin family B member 12), were increased in BAT positive, whereas proatherogenic and prothrombotic factors, including acute phase protein ORM2 (orosomucoid 2), APOD (apolipoprotein D), FGA (fibrinogen A), and FGB (fibrinogen B), were significantly lower in individuals with active BAT. Likewise, the circulating concentrations of inflammatory markers, such as IL-6 (interleukin-6), were reduced in BAT positive versus BAT negative.\n                    <\/jats:p>\n
