Interleukin-6 Inhibitor Suppresses Hyperalgesia Without Improvement in Osteoporosis in a Mouse Pain Model of Osteoporosis

The aim of this study was to evaluate skeletal pain associated with osteoporosis and examine the inhibitory effect of interleukin-6 (IL-6) on pain in ovariectomized (OVX) mice. The mechanism of osteoporotic pain in OVX mice was evaluated by examining pain-related behavior and immunohistochemistry. The effects of IL-6 receptor inhibitor (IL-6i) on these parameters were also assessed. Eight-week-old female ddY mice were ovariectomized and assigned...
