OBJECTIVE: To observe the protection against periodontal bone loss in the Sprague-Dawley (SD) rats periodontitis model, with the recombined plasmid pcDNA3.1+/kgpcd as DNA gene vaccine.
METHODS: PcDNA3.1+/kgpcd was delivered into rats by submandibular gland-targeted injection. The anti-KGPcd sIgA in saliva was measured by indirect ELISA method. Immunohistochemistry staining was used to assess the protection in the animal model.
RESULTS: The level of specific anti-KGPcd sIgA in saliva of the experimental group was significantly higher than that of control group. HE staining showed that immunization with recombined plasmid pcDNA3.1+/kgpcd could protect or minimize tissue destruction caused by subsequent P. gingivalis challenge in the rat model.
CONCLUSIONS: The results indicate that pcDNA3.1+/kgpcd was a good candidate for anti-periodontitis gene vaccine and could provide protection against Porphyromonas gingivalis-caused periodontitis in rat lesion model.
