Decreased Fat Mass in Interleukin-1 Receptor Antagonist–Deficient Mice
Open accessAbstract
Interleukin (IL)-1 is a regulator of inflammation but is also implicated in the control of energy homeostasis. Because the soluble IL-1 receptor antagonist (IL-1Ra) is markedly increased in the serum of obese patients and is overexpressed in white adipose tissue in obesity, we studied the metabolic consequences of genetic IL-1Ra ablation in mice. We have shown that IL-1Ra−/− mice have a lean phenotype due to decreased fat mass, related to a defect in adipogenesis and increased energy expenditure. The adipocytes were smaller in these animals, and the expression of genes involved in adipogenesis was reduced. Energy expenditure as measured by indirect calorimetry was elevated, and weight loss in response to a 24-h fast was increased in IL-1Ra−/− animals compared with wild-type mice. Lipid oxidation of IL-1Ra−/− mice was higher during the light period, reflecting their reduction in diurnal food intake. Interestingly, IL-1Ra−/− and IL-1Ra+/− mice presented an attenuation in high-fat diet–induced caloric hyperphagia, indicating a better adaptation to hypercaloric alimentation, which is in line with the role of IL-1Ra as a mediator of leptin resistance. Taken together, we show that IL-1Ra is an important regulator of adipogenesis, food intake, and energy expenditure.

“The increase in abdominal fat mass is associated with a chronic elevation of the circulating concentrations of inflammatory mediators including several acute-phase inflammatory proteins such as CRP (46,47) , proand anti-inflammatory cytokines, adhesion molecules and pro-thrombotic molecules (22,47 -49) .”

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.
