ochracea ATCC33596, C. sputigena ATCC33624, Eikenella corrodens ATCC23834, Eubacterium nodatum ATCC33099, Fusobacterium nucleatum ATCC49256, Micromonas micros ATCC33270, Porphyromonas gingivalis FDC381, Prevotella intermedia ATCC25611, P. loeschii ATCC15930, P. nigrescens ATCC33563, Streptococcus gordonii ATCC49818, S. mutans ATCC25175, S. sanguis ATCC10556, Treponema denticola ATCC35405, Tannerella forsythia ATCC49307 and Veillonella parvula ATCC10790. Due to the extensive variability in

mediator levels across the population, the data were all transformed using a log10 transformation and the antibody data were transformed using a log2 transformation. Antibody data were standardized using the antibody baseline mean and standard deviation

to create a Z-statistic for each individual animal [46]. An analysis of variance (ANOVA) was used to determine Fulvestrant research buy differences among the baseline disease categories with mTOR inhibitor a post-hoc Holm–Sidak assessment for individual group differences. Spearman’s correlation on ranks was used to determine relationships between the various host response variables, as well as to the periodontal presentation of the animals. Figure 1 shows the levels of these mediators in the control and experimental population during pregnancy, at baseline and after ligation of teeth in two quadrants (MP) or four quadrants (D). The results in Fig. 1a show substantial elevations in IL-6 occurring in the experimental animals at the time of delivery, while PGE2 and BPI were both increased over baseline, particularly at MP. IL-8, MCP-1 and LBP all decreased from baseline through the ligation phase of the study. The only change noted in the control animals (Fig. 1b) was an increased level of PGE2 at MP. IL-1β, MIP-1α, TNF-α and IL-12p40

were detected in <5% of the serum samples tested and thus are not included in the data presentation. Comparisons of the various mediator levels between the experimental and control groups at each time-point also demonstrated that levels of IL-6, IL-8 and MCP-1 were significantly different at delivery, while only LBP was significantly different at baseline between these groups. Due to the inherent clinical variation in the Anidulafungin (LY303366) animals as they entered the study, Fig. 2a,b stratifies the baboons based upon clinical presentation at baseline into healthy (H) (CIPD <20), gingivitis (G) (CIPD 20–<50) and periodontitis (P) (CIPD >50) subgroups and depicts the levels of the various mediators in serum from these subgroups of animals. The results compare changes in the levels of the various inflammatory mediators during the 6 months of ligature-induced disease. No differences were observed in the levels of any of the analytes in serum comparing these experimental subgroups to the control animals at baseline.
