15 J Gen Microbiol Oct;132(10): Links Demonstration of shared antigenic determinants between Streptococcus mutans BHT cell membrane, human heart tissue and myosin using monoclonal antibodies to S. mutans. Doyle G, Everhart D, Mallett C, Ayakawa G, Bleiweis AS. Monoclonal antibodies (MAb) raised to intact Streptococcus mutans P-4 cells (serotype e) were used to demonstrate the presence of shared antigenic determinant(s) between S. mutans BHT (serotype b) cell membranes and human heart tissue. MAb binding to both BHT membrane and human heart tissue was demonstrated by ELISA. Common antigens were identified by immunoblot analysis following separation of BHT membrane components and human heart antigens by SDS-PAGE. MAb 22C4 recognized three polypeptides from the BHT membrane preparation, having molecular masses of 42, 56 and 85 kda. MAb 22C4 also recognized an 85 kda component and a 200 kda component from human heart tissue. MAb D159 was specific for a single 82 kda polypeptide in BHT membrane, and also bound to two high molecular mass components in human heart (165 and 200 kda). When both MAb D159 and 22C4 were first absorbed with S. mutans P-4 cells, subsequent reactivity to the aforementioned BHT membrane components was inhibited, indicating that these cross-reactive components are found in S. mutans P-4 as well as in S. mutans BHT microorganisms. Competitive binding analysis showed that both MAb D159 and MAb 22C4 bound to myosin, indicating that S. mutans BHT membrane, human heart tissue and myosin share at least one immunodeterminant. This indicates that myosin could be the crossreactive tissue component in human heart.
16 Protective efficacy of a targeted anti-caries DNA plasmid against cariogenic bacteria infections. Xu QA, Yu F, Fan MW, Bian Z, Chen Z, Peng B, Jia R, Guo JH. Key Laboratory for Oral Biomedical Engineering of Ministry of Education, School&hospital of Stomatology, Wuhan University, Luoyu Road 237, Wuhan, Hubei, China. We have previously reported that a targeted anti-caries DNA plasmid pgja-p/vax which was constructed against the antigenic determinants of Streptococcus mutans (S. mutans) successfully induced antibody responses in mice and monkeys. The present study explored the protective efficacy of pgja-p/vax against cariogenic bacterial challenge. Groups of rats were orally challenged with S. mutans or Streptococcus sobrinus (S. sobrinus) and then immunized with pgja-p/vax or the vector pvax1 intranasally. Serum IgG and salivary IgA antibody levels were assessed by an enzyme-linked immunosorbent assay and caries activity was evaluated by the Keyes method. The results showed that specific salivary IgA antibody responses were induced following intranasal vaccination with pgja-p/vax. Moreover, immunization with pgja-p/vax resulted in significantly reduced enamel and dentinal caries lesions in rats after S. mutans infection and significantly reduced enamel caries lesions after S. sobrinus infection. Thus, pgja-p/vax was not only protective toward S. mutans infection, but also provided cross-strain protection against S. sobrinus infection in rats.
17 Caries Res. 1999;33(1):4-15. Secretory immunity in defense against cariogenic mutans streptococci. Russell MW, Hajishengallis G, Childers NK, Michalek SM. Microbiology, University of Alabama at Birmingham, Ala , USA. Specific immune defense against cariogenic mutans streptococci is provided largely by salivary secretory IgA antibodies, which are generated by the common mucosal immune system. This system is functional in newborn infants, who develop salivary IgA antibodies as they become colonized by oral microorganisms. The mechanisms of action of salivary IgA antibodies include interference with sucrose-independent and sucrose- dependent attachment of mutans streptococci to tooth surfaces, as well as possible inhibition of metabolic activities. The goal of protecting infants against colonization by mutans streptococci might be accomplished by applying new strategies of mucosal immunization that would induce salivary IgA antibodies without the complications of parenteral immunization. Strategies of mucosal immunization against mutans streptococci currently under development include the use of surface adhesins and glucosyltransferase as key antigens, which are being incorporated into novel mucosal vaccine delivery systems and adjuvants. The oral application of preformed, genetically engineered antibodies to mutans streptococcal antigens also offers new prospects for passive immunization against dental caries.

26 Curr Med Res Opin Jun;24(6): Epub 2008 Apr 30. Links The potential impact of periodontal disease on general health: a consensus view. Williams RC, Barnett AH, Claffey N, Davis M, Gadsby R, Kellett M, Lip GY, Thackray S. University of North Carolina, School of Dentistry, Chapel Hill, NC 27599, USA. ray_williams@dentistry.unc.edu BACKGROUND: Evidence for a link between periodontal disease and several systemic diseases is growing rapidly. The infectious and inflammatory burden of chronic periodontitis is thought to have an important systemic impact. Current evidence suggests that periodontitis is associated with an increased likelihood of coronary heart disease and may influence the severity of diabetes. SCOPE: This paper represents a UK and Ireland cross-specialty consensus review, undertaken by a group of physicians and dentists. The consensus group reviewed published evidence (PubMed search for review and original articles), focusing on the past 5 years, on the contributory role of periodontal disease to overall health. In particular, evidence relating to a role for periodontal disease in cardiovascular disease and in diabetes was considered. FINDINGS: Initial studies of large epidemiological data sets have sought to find links between periodontitis and systemic disease outcomes, but a causal relationship still needs to be demonstrated between periodontal disease, cardiovascular disease and diabetes through prospective studies. There is a need for prospective studies assessing the association between periodontal disease and patients at particular risk of cardiovascular events which will allow assessment of both cardiovascular disease clinical endpoints and surrogate markers of cardiovascular risk. Of note, periodontal disease is also often more severe in subjects with diabetes mellitus, a group at already increased risk for cardiovascular events. CONCLUSIONS: While further research is needed to define the populationattributable risk of periodontal disease to both cardiovascular diseases and to diabetes control and progression, health education to encourage better oral health should be considered as part of current healthy lifestyle messages designed to reduce the increasing health burden of obesity, cardiovascular disease and diabetes.

Department of Periodontics, University of Texas Health Science Center, San Antonio, Texas, USA. THE PURPOSE OF REVIEW: Periodontal diseases are inflammatory conditions that were once thought to have manifestations localized to the oral cavity alone, and were therefore considered the concern of only dentists and other oral health professionals. Emerging evidence has changed this view and now suggests that periodontal diseases may play a role in numerous conditions that impact systemic well-being, including diabetes mellitus. This review examines the relationships that exist between periodontal diseases and diabetes mellitus, with a focus on potential common pathophysiologic pathways including those associated with inflammation, altered host responses, and insulin resistance. RECENT FINDINGS: Periodontal inflammation is associated with an elevated systemic inflammatory state and an increased risk of major cardiovascular events such as myocardial infarction and stroke, adverse pregnancy outcomes such as preeclampsia, low birth weight, and preterm birth, and altered glycemic control in people with diabetes. Intervention trials suggest that periodontal therapy, which decreases the intraoral bacterial bioburden and reduces periodontal inflammation, can have a significant impact on systemic inflammatory status. Evidence suggests that periodontal therapy is associated with improved glycemic control in many patients with both diabetes and periodontal diseases. SUMMARY: Recognition of the bilateral relationships between oral and systemic health will challenge physicians and dentists to work together closely in the future when managing patients with diabetes and periodontal disease.
