Abstract:

Fibrous dysplasia (FD)is a rare bone disease in which fibrous tissue replaces bone tissue, and is caused by a GNAS mutation in skeletal stem cells.Currently, there is no cure for FD. Receptor activator for nuclear factor-κB ligand (RANKL)has been discovered to be highly expressed in FD lesions, which mediates osteoclast hyperfunction and causes pathological bone fractures in severe cases. RANKL is thus a possible therapeutic target for FD. RANKL inhibition in FD treatment draws attention from researchers at home and abroad. Clinical case studies and laboratory studies have validated the relieving effect of RANKL inhibition on skeletal symptoms of FD. The current progress of RANKL inhibition in the management of FD is reviewed in this article.

Key words: fibrous dysplasia, RANKL, targeted therapy
