We are testing a new system for linking grants to scientists.
The funding information displayed below comes from the
NIH Research Portfolio Online Reporting Tools and the
NSF Award Database.
The grant data on this page is limited to grants awarded in the United States and is thus partial. It can nonetheless be used to understand how funding patterns influence mentorship networks and vice-versa, which has deep implications on how research is done.

Social Stress Modulates Neuropeptide Y in a Model Fo Periodontal Inflammation
DESCRIPTION (provided by applicant): Periodontitis is an infectious disease caused by the formation of bacterial plaque on teeth. Porphyromonas gingivalis (P. gingivalis) is one of these bacteria, and has been used in many experimental models of periodontitis to replicate the inflammation and bone resorption seen in clinical cases. It is well understood that stress exacerbates the inflammation and bone resorption associated with chronic periodontitis, and that the primary cause of the tissue destruction and tooth loss is the prolonged inflammation and presence of proinflammatory cytokines such as Interleukin-12 (IL-12). Furthermore, neuropeptides, such as the highly abundant neuropeptide Y (NPY), have been found at the site of infected periodontal tissue and may play a role in modulating norepinephrine and subsequent inflammation. Norepinephrine is thought to promote inflammation by modulating cytokine release and is thought to be involved in immune cell trafficking. Using a murine model of social stress along with transgenic mouse technology and antagonists, we will examine the relationship of IL-12, NPY, and norepinephrine in the absence of infection in order to elucidate the modulatory mechanisms in vivo. Additionally, we will manipulate IL-12, NPY, and norepinephrine in a mouse model of stress-exacerbated chronic periodontitis to determine whether blocking any of these mediators can resolve inflammation and [bone resorption] associated with the deleterious effects of periodontitis. Exploring the specific mechanisms of periodontal inflammation and [bone resorption] will aid in identifying novel therapeutic targets that will improve the clinical outcomes of chronic periodontitis. PUBLIC HEALTH RELEVANCE: The experience of stress worsens and prolongs inflammation caused by chronic periodontitis. This prolonged inflammation can lead to tissue destruction, [bone resorption], and tooth loss. Understanding the role of neuropeptide Y in stress and periodontal inflammation will lead to not only better understanding the mechanisms of inflammation and [bone resorption], but also to novel treatment strategies and therapeutic targets that can prevent tissue destruction and tooth loss caused by chronic periodontitis.
