Intracellular Invasion by Streptococcus mutans: Significance in Disease
5/17/13-3/31/18
RO1 DE02255
The goals of this application are to conduct the functional analysis of the collagen-binding protein Cnm and to characterize the role of Cnm in host-bacteria interactions. To achieve these goals, we propose to use in vitro approaches to further characterize, genetically and biochemically, Cnm and its associated proteins, an ex vivo adhesion model to examine the role of Cnm in the colonization of heart tissues, and an in vivo rabbit endocarditis model to conclusively demonstrate the contribution of Cnm to the pathogenesis of infective endocarditis.

Controlled-Release in situ of antibiofilm agents via pH-activated Nanoparticle-carriers
4/1/13-3/31/15
2013 IADR/GSK Innovation in Oral Care Award
We have devised an exciting approach to deliver antibiofilm agents locally using polymer-based nanoparticle-carriers (NPC) that bind avidly to both tooth-pellicle and biofilm-matrix. Our nanocarrier contains pH-responsive elements that facilitate controlled-release of therapeutic agents within acidic environments. Moreover, we have proven antibiofilm agents (farnesol and apigenin) that can be chemically linked to and released from NPC. Farnesol is a membrane-targeting agent that is effective at acidic-pH while apigenin inhibits exopolysaccharides synthesis. We hypothesize that pH-activated nanoparticles will enhance localization and provide sustained release of distinctive antibiofilm agents in situ where active biofilm formation occurs, thereby enhancing drug efficacy in vivo.

Cell Based Regeneration of Salivary Glands
8/1/12-7/31/16
R01DE022949

This proposal combines the tools of mouse genetics with recent advances in biomaterial engineering to ask two questions:

  1. Can isolated progenitor cell populations be used to reconstitute functional secretory structures in a damaged salivary gland?
  2. Does the introduction of progenitor cells into a dysfunctional gland induce endogenous repair and/or secretion?
