Bone resorption is regulated by various cytokines. In postmenopausal osteoporosis, bone loss due to estrogen deficiency is closely related to the production of bone-resorbing cytokine. Especially, the increased production of IL-1, IL-6 and TNF-α could induce the expression of RANKL in bone tissues to enhance osteoclastogenesis. Relationship between estrogen deficiency and various cytokines is important to clarify the pathogenesis of postmenopausal osteoporosis.
