To investigate whether oligomerization domains (NODs) are involved in Porphyromonas gingivalis-induced interleukin (IL)-6, IL-8, and vascular cell adhesion molecule (VCAM)-1 expression beyond Toll-like receptors (TLRs), we investigated the role of NOD1/2 in P. gingivalis-induced IL-6, IL-8, and VCAM-1 expression in human gingival fibroblasts (hGFs) and(More)
BACKGROUND The mechanism by which Porphyromonas gingivalis regulates intracellular adhesion molecule 1 (ICAM-1) expression in human periodontal ligament cells (hPDLCs) and human gingival fibroblasts (hGFs) is unknown. The aim of this study is to investigate whether nucleotide binding oligomerization domain-containing protein (NOD) 1 and NOD2 are involved in(More)
OBJECTIVE The aim of this study was to investigate the roles of nucleotide-binding oligomerization domain-containing protein 1/2 (NOD1/2) and Toll-like receptor 4 (TLR4) in mediating the adhesion of monocytes to periodontal fibroblasts through leucocyte function-associated antigen-1 (LFA-1) and very late antigen-4 (VLA-4). DESIGN The expression of NOD1,(More)
OBJECTIVE Porphyromonas gingivalis induces nitric oxide (NO) synthesis in human umbilical vein endothelial cells (HUVECs). Peroxisome proliferator-activated receptor (PPARγ) has an anti-inflammation function, and its involvement in this NO induction process requires elucidation. Here, we focused on PPARγ expression in HUVECs exposed to P. gingivalis, and(More)
PURPOSE OF THE STUDY Follicular dendritic cell-secreted protein (FDC-SP) has been found to be expressed in periodontal ligament (PDL), a layer of soft connective tissue between tooth root and alveolar bone, and involved in immunoreaction. This study was performed to explore the potential role of FDC-SP in periodontal disease. MATERIALS AND METHODS The(More)
