Forsythia suspensa metabolites have many bioactivities, such as selective immuno suppression, antioxidation, anti-hepatic injury, etc. In the present study, the interactions of the three metabolites with BSA have been investigated in a buffer (pH 7.40) using multi-spectroscopic techniques in
Porphyromonas gingivalis is considered the principal etiologic agent and keystone pathogen of chronic periodontitis. As an auxotrophic bacterium, it must acquire heme to survive and multiply at the infection site. P. gingivalis HmuY is the first member of a novel family of hemophore-like proteins.
Tannerella forsythia, a Gram-negative anaerobe implicated in periodontitis, has been detected within human buccal epithelial cells and shown to invade oral epithelial cells in vitro. We have previously shown that this bacterium triggers host tyrosine kinase-dependent phosphorylation and
