| Research Abstract |
We planned to clarify the characteristics of BDNF-induced periodontal tissue regeneration, and to investigate the genetic association of trkB with periodontal tissue regeneration by BDNF. In vitro study, two weeks after the BDNF application, periodontal tissue regeneration was insufficient, but invasion of epithelial cells to defects was not observed. TrkB, PCNA and OPN-positive cells were detected on the denuded root surface, around the regenerating alveolar bone and in the soft connective tissue of regenerating periodontal tissues. TrkB positive cells may quickly responded to applied BDNF and started to proliferate and differentiate for the periodontal tissue regeneration within 2 weeks. Furthermore, we investigated the trkB single nucleotide polymorphisms(SNPs) which are reported to have some relationships with Alzheimer' s disease.
