Chronic oral application of a periodontal pathogen results in brain inflammation, neurodegeneration and amyloid beta production in wild type mice
(A) Immunofluorescence microscopy. Red: Pg, Blue: DAPI. (B) Images showing intra-, peri- and extra-cellularly localized Pg. (C) Number of Pg/gingipain detected per field (220μm X 160μm). N = 9 mice for experimental and N = 10 mice for control group. (D) Copy number of Pg 16S RNA genes detected in genomic DNA isolated from 5FFPE samples/mouse, N = 5 mice/group. Y- axis: number of Pg/gingipain per field for (C) and copy number of 16S rRNA genes from genomic DNA for (D). X-axis: C (control), E (experimental) group.
