Osteocytes act as mechanosensors to control local bone volume. However, their roles in the homeostasis of remote organs are largely unknown. We show that ablation of osteocytes in mice (osteocyte-less [OL] mice) leads to severe lymphopenia, due to lack of lymphoid-supporting stroma in both the bone marrow and thymus, and complete loss of white adipose tissues. These effects were reversed when osteocytes were replenished within the bone. In contrast, neither in vivo supply of T cell progenitors and humoral factors via shared circulation with a normal parabiotic partner nor ablation of specific hypothalamic nuclei rescued thymic atrophy and fat loss in OL mice. Furthermore, ablation of the hypothalamus in OL mice led to hepatic steatosis, which was rescued by parabiosis with normal mice. Our results define a role for osteocytes as critical regulators of lymphopoiesis and fat metabolism and suggest that bone acts as a central regulator of multiple organs.

We report in this paper the case of female patient, hypertriglyceridemia associated with milky serum and hyperglycemia have been the alarm signal of a lupus-associated pancreatitis, the confirmation of this entity was done with elevated rate of serum lipase activity. It is about a 33 years age female. She has as unique antecedent a lupus diagnosed on January of the same. The patient was admitted on august 2013 for another episode of lupus associated to the lower lamb edema with a rate of C3 at 0.4 g/L (0.82-1,93) and C4 at 0.05 g/L (0.15-0.57). One day after the beginning of the corticotherapy, the patient presented hyperthermia, ataxis and behavior troubles, epigastric and articular pains and vomiting. Biochemical tests found hyperglycemia at 38.9 mmol/L (3.9-6.1), dyslipidemia with hypertriglyceridemia at 15.7 mmol/L (0.3-1.7) and total cholesterol rate at 5.2 mmol/L (<5.2) associated with milky serum. Haematological tests objective normocytic normochromic anemia with 81 g/L of hemoglobin, lymphopenia at 0.88 G/L and normal platelet rate. Lupus associated pancreatitis was suggested and confirmed biologically with an hyperlipasemia at 180 UI/L (8-78) and radiologicaly with the image of focal hepatic steatosis. We conclude that on the presence of lupus, gastrointestinal and/or biological signs must motivate the measurement of the serum lipase activity as quickly as possible to assess the diagnosis of lupus-associated pancreatitis.
