CONTEXT Cannabinoid CB(1) receptor blockade decreases weight and hyperinsulinemia in obese animals and humans in a way greatly independent from food intake. OBJECTIVE The objective of this study was to investigate the regulation and function of the endocannabinoid system in adipocytes and pancreatic beta-cells. DESIGN, SETTING, AND PATIENTS Mouse(More)
To investigate the expression of the endocannabinoid 1 and 2 receptors by human adipocyte cells of omental and subcutaneous fat tissue, as well as to determine whether these receptors are functional. The expression of CB1 and CB2 receptors on human adipocytes was analyzed by western blotting, immunohistology and immunocytology. We also investigated(More)
In addition to the well-known role of adipose tissue in energy metabolism, it has recently been demonstrated that this tissue can secrete a large array of molecules, including inflammatory cytokines. Furthermore, recent studies suggest that adipose cells can behave as immune cells. Therefore, the aim of this study was to determine the presence of the two(More)
Adipose stem cells have gained great interest in plastic and reconstructive surgery with their ability to improve engraftment after fat transfer for soft tissue filling. It is therefore essential to know the effect of the drugs commonly used during the lipoaspiration procedure, such as lidocaine and adrenaline. Indeed, these drugs are infiltrated at the fat(More)
OBJECTIVE Recently, an activation of the endocannabinoid system during obesity has been reported. More particularly, it has been demonstrated that hypothalamic levels of both endocannabinoids, 2-arachidonoylglycerol and anandamide (N-arachidonoylethanolamine), are up-regulated in genetically obese rodents. Circulating levels of both endocannabinoids were(More)
Adipose tissue contains a stroma that can be easily isolated. Thus, human adipose tissue presents an source of multipotent stromal cells. In order to determine the implication of hematopoietic markers in adipocyte biology, we have defined part of the phenotype of the human adipose tissue-derived stromal cells, and compared this to fully differentiated(More)
BACKGROUND Low grade inflammation is one of the major metabolic disorders in case of obesity due to variable secretion of adipose derived cytokines called adipokines. Recently the nuclear protein HMGB1 was identified as an inflammatory alarmin in obesity associated diseases. However HMGB1 role in adipose tissue inflammation is not yet studied. OBJECTIVES(More)
Obesity leads to the appearance of an inflammatory process, which can be initiated even with a moderate weight gain. Palmitoylethanolamide (PEA) is an endogenous lipid, secreted by human adipocytes, that possesses numerous anti-inflammatory properties. The main purpose of this study was to investigate the anti-inflammatory effect of PEA on human adipocytes,(More)
Stress urinary incontinence (SUI), the most common type of incontinence in women, is a frequent and costly ailment responsible for an alteration in the quality of life. Although medical treatment gives some rather deceiving results, surgical techniques that include colposuspension or tension-free vaginal tape, employed in cases of urethral support defect,(More)
Breast augmentation or reconstruction is a major challenge in esthetic and reconstructive surgery. While autologous fat grafting (AFG) provides a natural filler and seems easy to harvest, AFG in breast surgery is still problematic especially due to the high resorption rate associated with megavolume transfer. Despite this pending issue, there is growing(More)
