Abstract
The present study was performed to investigate the binding between salivary proteins(low-molecular-weight mucin;MG2, amylase, proline-rich protenis;PRPs) and oral pathogens(Streptococcus gorconii,Actinomyces viscosus, Staphylococcus) by using solid-phase assay.
In the case of transferring proteins to Immobilon-P,S. gordonii binds to MG2. A. viscosus binds to MG2, amylase, and PRPs, and S. aureus binds to MG2 and amylase. On nitrocellulose membrane, S. gordonii and A. viscosus bind to MG2, amylase, and PRPs. S. aureus binds to MG2 and PRPs. However, rabbit anti-A. viscosus antisera and rabbit anti-S. aureus antisera showed cross reactivity to PRPs adsorbed to only nitrocellulose membrane in negative control experiments, which were done without bacterial overlay. The results were different according to the membrane used as solid-phase, which reflected the assat-sensitive nature of binding experiment.
PRPs and amylase are known to be comonents of tooth enamel pellicle. In addition, there was experimental evidence that PRPs and MG2 may covalently bind to oral mucosal epithelium. Considering above facts, the results of the present study can provide information on the interactions between salivary proteins and oral bacteria on tooth and oral mucoasl surfaces.
