(要約) Sudachitin, which is a polymethoxy flavonoid derived from the peer of Citrus sudachi, has several biological properties. However, the effect of sudachitin on human dental pulp cells (HDPCs) remains unclear. The aim of this study was to investigate whether sudachitin could decrease the expression of inflammatory mediators such as cytokines and prostaglandin in HDPCs stimulated with Pam3CSK4, a ligand for toll-like receptor (TLR) 2. HDPCs were pre-incubated with different concentrations of sudachitin (6.25, 12.5, 25, or 50 μM) and stimulated with Pam3CSK4 (100 ng/mL). The quantification of inflammatory cytokines (interleukin (IL)-6, IL-8, and C-X-C motif chemokine ligand (CXCL) 10) and prostaglandin E (PGE) were performed by enzyme-linked immunosorbent assay (ELISA). The expression of cyclooxygenase (COX)-2, a key enzyme for PGE formation, was analyzed by western blot. Moreover, the activations of cell signal pathways were examined by western blot analysis. Sudachitin suppressed IL-6, IL-8, CXCL10, and PGE production and COX-2 protein expression in Pam3CSK4-stimulated HDPCs. In addition, we revealed that nuclear factor-kappa B (NF-κB) and protein kinase B (Akt) pathways in the Pam3CSK4-stimulated HDPCs were inhibited by sudachitin treatment. These findings suggest that sudachitin can reduce inflammatory mediator production in HDPCs stimulated with TLR2 ligand by inhibiting NF-κB and Akt activations.

(要約) In recent years, in our super-aged society, where people are striving for health and longevity, aesthetic awareness and interest in the oral cavity are increasing among men and women of all ages and both sexes. In particular, the number of patients requesting tooth bleaching procedures for discolored teeth has been increasing. Tooth bleaching is a minimally invasive esthetic dentistry that can make patients smile. To meet the needs of these patients, Department of Cariology at the University of Tokushima Hospital has reestablished a system for patients to receive tooth bleaching treatment for discolored teeth. Therefore, we would like to report on the bleaching procedures we are performing at our department.

(要約) In response to pro-inflammatory cytokines such as interleukin (IL)-1β, dental pulp fibroblasts produce various inflammatory mediators, including IL-6, IL-8, CC chemokine ligand 20 (CCL20), and CXC chemokine ligand 10 (CXCL10), leading to the progression of pulpitis. IL-17/IL-17A (IL-17A) is a pro-inflammatory cytokine secreted by T helper (Th) 17 cells following their recruitment to inflamed sites; however, the roles of IL-17A during pulpitis remain unclear. The purpose of this study was to investigate the effect of IL-17A on IL-6, IL-8, CCL20 and CXCL10 production by human dental pulp fibroblasts (HDPFs) in vitro. IL-17A at a concentration of 100 ng/ml induced the production of 10 times more IL-8 and 4 times more CXCL10, but not IL-6 and CCL20, compared to controls. Co-stimulation of HDPFs with IL-17A and IL-1β synergistically enhanced the production of IL-6, CCL20, IL-8 and CXCL10. IL-1β increased expression of IL-17 receptor/IL-17RA (IL-17R) on HDPFs. Moreover, the cell signal pathways of p38 mitogen-activated protein kinase (MAPK) and nuclear factor-κB (NF-κB) were more potently activated by simultaneous stimulation with IL-17A and IL-1β. These findings suggest that IL-17A participates in the progression of dental pulp inflammation through the enhanced production of inflammatory mediators in HDPFs.

Hitomi Kuramoto, Tadashi Nakanishi, Daisuke Takegawa, MIEDA Katsuhiro and Keiichi Hosaka : Caffeic Acid Phenethyl Ester Induces Vascular Endothelial Growth Factor Production and Inhibits CXCL10 Production in Human Dental Pulp Cells, Current Issues in Molecular Biology, 44, 11, 5691-5699, 2022. (要約) The survival rate of root non-vital teeth is lower than that of vital teeth. Therefore, to preserve the dental pulp is very important. The vascular endothelial growth factor (VEGF) is the most potent angiogenic factor involved in the vitality of dental pulp including reparative dentin formation. Caffeic acid phenethyl ester (CAPE) is a physiologically active substance of propolis and has some bioactivities such as anti-inflammatory effects. However, there are no reports on the effects of CAPE on dental pulp inflammation. In this study, we investigated the effects of CAPE on VEGF and inflammatory cytokine production in human dental pulp cells (HDPCs) to apply CAPE to an ideal dental pulp protective agent. We found that CAPE induced VEGF production from HDPCs. Moreover, CAPE induced the phosphorylation of p38 mitogen-activated protein kinase (MAPK), extracellular signal-regulated kinases (ERK), and stress-activated protein kinase/c-Jun N-terminal kinase (SAP/JNK) in HDPCs. Furthermore, CAPE inhibited C-X-C motif chemokine ligand 10 (CXCL10) production in Pam3CSK4- and tumor necrosis factor-alpha (TNF-α)-stimulated HDPCs. In conclusion, these results suggest that CAPE might be useful as a novel biological material for vital pulp therapy by exerting the effects of VEGF production and anti-inflammatory activities.

(要約) Caffeic acid phenethyl ester (CAPE), the main component of propolis, has various biological activities including anti-inflammatory effect and wound healing promotion. Odontoblasts located in the outermost layer of dental pulp play crucial roles such as production of growth factors and formation of hard tissue termed reparative dentin in host defense against dental caries. In this study, we investigated the effects of CAPE on the upregulation of vascular endothelial growth factor (VEGF) and calcification activities of odontoblasts, leading to development of novel therapy for dental pulp inflammation caused by dental caries. CAPE significantly induced mRNA expression and production of VEGF in rat clonal odontoblast-like KN-3 cells cultured in normal medium or osteogenic induction medium. CAPE treatment enhanced nuclear factor-kappa B (NF-B) transcription factor activation, and furthermore, the specific inhibitor of NF-B significantly reduced VEGF production. The expression of VEGF receptor- (VEGFR-) 2, not VEGFR-1, was up regulated in KN-3 cells treated with CAPE. In addition, VEGF significantly increased mineralization activity in KN-3 cells. These findings suggest that CAPE might be useful as a novel biological material for the dental pulp conservative therapy.

(要約) Odontoblasts located in the outermost layer of dental pulp form a natural barrier between mineralized tissues, dentin, and soft tissues, dental pulp, of the vital tooth, and they first recognize caries-related pathogens and sense external irritations. Therefore, odontoblasts possess a specialized innate immune system to fight oral pathogens invading into dentin. Generally, the rapid initial sensing of microbial pathogens, especially pathogen-associated molecular patterns (PAMPs) shared by microorganisms, are mediated by pattern recognition receptors (PRRs), such as Toll-like receptor and the nucleotide-binding oligomerization domain (NOD). The innate immune responses in odontoblasts initiated by sensing oral pathogens provide host protective events, such as inflammatory reactions, to produce a variety of pro-inflammatory mediators, including chemokines and cytokines. These attract various inflammatory cells and cause antibacterial reactions, such as the production of defensins, to kill microorganisms in the proximal region of the odontoblast layer. This review focuses on innate immunity, especially cellular and molecular mechanisms regarding the sensing of PAMPs from oral pathogens by PRRs, in odontoblasts and provides information for future studies for the development of novel therapeutic strategies, including diagnosis and treatment, to prevent exceeding dental pulp inflammation and preserve the dental pulp tissues.
