Abstract

The adipose tissue exerts a double function that is crucial for energy homeostasis. On the one hand, it is the only organ suited to stock triglycerides in highly specialized cells, the adipocytes. On the other hand, the adipose tissue produces biologically active molecules, collectively named "adipokines", which have been implicated in energy balance and glucose and lipid metabolism. Both adipocytes and cells of the stromal fraction participate in this function of secretion. The adipokines acts locally, in an autocrine or paracrine manner, and distantly (endocrine), on various targets, including muscles, the liver and the hypothalamus. Some adipokines, as TNFalpha and IL6, promote insulin resistance and inflammation, whereas others, as leptin and adiponectin, are required for energy and glucose homeostasis. In obesity, adipose cell hypertrophy and the recruitment of macrophages alter the secretory function and induce an inflammatory profile in the adipose tissue. Analyses of gene expression suggest that hypoxia is one of the factors favoring the attraction of the macrophages. The local and systemic consequences of interactions between macrophages and adipocytes are currently actively studied, to understand their potential implication in the metabolic and cardiovascular complications associated with obesity.

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.
