Three different white adipose tissue-related disorders, whether due to its excess (obesity), absence (lipoatrophies) or aberrant distribution (lipodystrophies), are paradoxically able to induce metabolic insulin resistance syndrome. The respective roles played by quantitative and qualitative anomalies of adipose tissue, gluco- and lipo-toxicity, liver and muscle insulin resistance, low-grade fat inflammation and immune alterations are not yet perfectly understood. In contrast to most organ transplantations that are often complicated by post-transplantation diabetes, diabetes cell therapy is associated with body weight loss, which is possibly related to the antiadipogenic effects of mTOR inhibitors (rapamycin or sirolimus). The aim of this study is thus to determine and monitor blood interleukin-7 and other cytokine levels; metabolic parameters; and fat mass distribution with DEXA and RMN, before and after a immunosuppressive regimen in patients receiving different kinds of transplantation (liver, kidney or islets) with normal weight and no type 2 diabetes before transplantation. In these patients, blood samples will be taken before and after transplantation, as will adipose tissue during the transplantation surgery, in order to constitute a plasma serum, gene and tissue bank for improving our knowledge of disorders linking fat mass, insulin resistance and immunity, especially post-transplantation diabetes.
