Research Abstract |
Osteoclasts have been believed to be bore-resorbing cells, which play an essential role in bone homeostasis. However, osteoclast-specific conditional knockout mice, which show a severe osteopetrotic phenotype due to a lack of bone-resorbing activity, were resistant to the development of obesity associated with ageing and high fat diet. These results clearly suggested that osteoclasts are involved in the pathogenesis of the obesity, and probably subsequent diabetes.
