Summary

Pathological changes in sensory neurons is thought to contribute to chronic pain associated with fibromyalgia, neuropathic pain, irritable bowel syndrome (IBS), pancreatitis, gastroesophageal reflux disease (GERD) and cancer. In addition to producing debilitating pain sensations, hyperactive sensory neurons can release bioactive peptides that further exacerbate disease. Research in the Davis laboratory focuses on the role of growth factors in the development and adult plasticity of the central and peripheral nervous system. This work is being conducted in collaboration with Dr. Kathryn Albers (Department of Medicine), who has created lines of transgenic mice overexpressing specific growth factors; and Dr. H. Richard Koerber (Department of Neurobiology), who is examining plasticity of second-order spinal cord neurons. Currently, Dr. Davis's research is focused on somatic and visceral pain and growth factors of the NGF and GDNF families. Specifically, he has found that these growth factors (that are required for embryonic development of primary afferents) are upregulated in models of chronic pain. The lab also has strong evidence that this upregulation directly contributes to the development of persistent pain states. The goal of this research is to determine how these changes contribute to the development of chronic pain, with an emphasis on the transcriptional events and downstream signaling that controls the response properties of sensory neurons. This information may lead to identification of new targets that could be the basis of novel therapies for chronic somatic and visceral pain.
