[Crosstalk between bone and adipose tissue in chronic kidney disease]

Within the concept that hormones are regulated by a cycle of reciprocity, the fact that osteoblasts and adipocytes are developed from mesenchymal stem cells and that bone remodeling is regulated by leptin brings up the idea of possible bone participation in energy metabolism and vice-versa. Recent studies have shown that the differentiation and function of these bone cells are regulated by leptin, which seems to trigger a bimodal response, via sympathetic nervous system, and a local response, in which leptin acts on the bone. In fact, studies have shown complex interactions between bone, adipose tissue and brain. However, there are few studies on crosstalk in patients with chronic kidney disease (CKD). These patients have a tendency to decreased bone mineral density and high levels of leptin. Then, this article presented a review of potential involvement of adipose tissue and bone mass in patients with CKD.
