Influence of mouse prolactin-inducible protein in saliva on the aggregation of oral bacteriaEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: In this study it was confirmed that mPIP plays a role in the aggregation of oral bacteria. The salivary components promoting aggregation of oral bacteria are considered to be part of the oral defense mechanisms so these findings provide insight into a possible function of mPIP in host defense by promoting aggregation of oral bacteria.

Regulatory roles of β-catenin and AP-1 on osteoprotegerin production in interleukin-1α-stimulated periodontal ligament cellsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.

Analysis of Streptococcus mutans biofilm proteins recognized by salivary immunoglobulin AEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: The bacterial molecules recognized by caries-free saliva are significant factors for S. mutans caries formation, and their inhibition could be a therapeutic target. In addition, saliva of caries-free subjects includes significant IgA antibody against antigen I/II of S. mutans, indicating a protective mechanism. However, microorganisms may protect themselves from host immune attack by forming biofilms and decreasing expression of antigen I/II. (Source: Oral Microbiology and Immunology)
