Chronic oral application of a periodontal pathogen results in brain inflammation, neurodegeneration and amyloid beta production in wild type mice
(A) CA1 and DG regions from control mouse. There is no FJC staining in these regions. (B) CA1 and DG regions which show FJC+ staining in representative section from an experimental mouse. Green: FJC staining indicating degenerating neurons. Blue: DAPI. (C) FJC+ cells are present in the experimental but not in control mice. Positive cells were counted in 220μm x 175μm rectangular areas. Representative of N = 4 mice/group.
