Protective and Destructive Immunity in the Periodontium: Part 1—Innate and Humoral Immunity and the PeriodontiumLab. of Molecular Microbial Immunity, Eastman Department of Dentistry, Eastman Dental Center, Box-683, 625 Elmwood Ave., and Centre for Oral Biology, Dept. of Microbiology and Immunology, School of Medicine and Dentistry, The University of Rochester Medical Center, Rochester, NY 14620, USA; andy_teng{at}urmc.rochester.edu Based on the results of recent research in the field, the present paper will discuss the protective and destructive aspects of the innate vs. adaptive (humoral and cell-mediated) immunity associated with the bacterial virulent factors or antigenic determinants during periodontal pathogenesis. Attention will be focused on: (i) the Toll-like receptors (TLR), the innate immune repertoire for recognizing the unique molecular patterns of microbial components that trigger innate and adaptive immunity for effective host defenses, in some general non-oral vs. periodontal microbial infections; (ii) T-cell-mediated immunity, Th-cytokines, and osteoclastogenesis in periodontal disease progression; and (iii) some molecular techniques developed and used to identify critical microbial virulence factors or antigens associated with host immunity (using Actinobacillus actinomycetemcomitans and Porphyromonas gingivalis as the model species). Therefore, further understanding of the molecular interactions and mechanisms associated with the hosts innate and adaptive immune responses will facilitate the development of new and innovative therapeutics for future periodontal treatments. Abbreviations used in the paper are as follows: A. actinomycetemcomitans (Aa), Actinobacillus actinomycetemcomitans; Ab, antibody; DC, dendritic cells; mAb, monoclonal antibody; pAb, polyclonal antibody; PAMP, pathogen-associated molecular patterns; P. gingivalis (Pg), Porphyromonas gingivalis; and TLR, Toll-like receptors.
Key Words: innate immunity TLR humoral Ig response dendritic cells (DC) pathogen-associated muscular patterns (PAMP)
