Abstract:
Objective To explore the splenic macrophages phenotype and secretory function of mice with periodontitis, so as to explore effects of periodontitis on macrophages. Methods 22 mice were randomly divided into periodental ligation group (group P10d ) and pseudo periodental ligation control group (group C), with 11 mice in each group. The experimental periodental ligation on mice lasted for 10 days before they were sacrificed. Flow cytometry was applied to detect the expression of M1 and M2 in mononuclear macrophages. Real-time PCR was applied to detect the relative expression of pro-inflammatory cytokines IL-1β and anti inflammatory cytokines IL-10. Results Compared with the control group C, the proportion of M1 macrophages in the periodontitis group decreased, and the ratio of M1/M2 was also decreased significantly, and IL-1β mRNA also down-regulated. Conclusions Chronic periodontal infection could down regulate the proportion of M1 macrophages , decrease ratio of M1/M2 and the expression of inflammatory cytokines IL-1βmRNA.
