The Role of Peripheral Nerve Function in Age-Related Bone Loss and Changes in Bone Adaptation

Abstract

Current osteoporosis therapies are able to treat the symptoms of osteoporosis, however little progress has been made toward understanding and addressing the underlying mechanisms contributing to age-related bone loss, or the ability to adapt to mechanical loading (exercise). Degeneration in peripheral nerve function with age may be one of these mechanisms, as neuropeptides affect the function of osteoblasts and osteoclasts in vitro, and nerve deactivation causes bone loss in vivo. This research investigates mechanisms by which peripheral sensory nerves influence bone maintenance and mechanotransduction using capsaicin-injected mice as a model of decreased peripheral sensory nerve function. We hypothesize that decreased sensory nerve function will result in increased functional adaptation of bone. In Aim 1 we investigated the relationship betweenperipheral sensory nerve function and bone structure.
