Chronic oral application of a periodontal pathogen results in brain inflammation, neurodegeneration and amyloid beta production in wild type mice
Results from immunofluorescence microscopy. (A) Hippocampus of a control mouse showing no Aβ42, (B) hippocampus of an experimental mouse showing presence of Aβ42. Red: Aβ42, Blue: DAPI. Images in green frame are negative controls (isotype controls). (C) Aβ42 plaques counted per field (1.8mm X 1.3mm rectangle) which encompasses the entire right hemisphere of the hippocampus using 40X magnification. The same size rectangle was used to count plaque in the cortex (D-F). N = 10 for control and N = 9 for experimental groups. Images are 40X (top panels) and 100X insets for A and B.
