Research Interests:


Periodontal disease is a chronic inflammatory disease characterized by gingival inflammation and periodontal bone loss. Invasion of etiological bacteria into periodontal tissues induces host responses which cause lateral tissue destruction and bone resorption. Helper T cell is pivotal in the establishment and optimization of adaptive immunity, therefore an important component of host response. Our research interest is to investigate host T cell responses induced by the important periodontitis etiological pathogen Porphyromonas gingivalis (Pg). Using a series of in vitro assays and in vivo models, we aim to elucidate the function of Pg-induced T cell response on periodontal disease development. Our goal is to determine the signaling pathways that promote differentiation of interested T cell subsets, and identify potential therapeutic targets for periodontal diseases.
