Substance-P and bone resorption

Sympathectomy is known to result in localized bone resorption in the middle ear and at other sites. (Sandhu et al 1989) Sherman & Chole (1996) found that sympathectomy induced bone resorption could be blocked by capsaicin in vivo. It was concluded that sympathectomy led to a secondary release of substance-P and then directly or indirectly to the activation of osteoclasts. Substance-P also stimulates bone resorption in vitro. It was hypothesized that substance-P is required for other types of bone remodleing, including adaptive bone remodeling.
