Article Title: Beneficial Effect of ACI-24 Vaccination on Aβ Plaque Pathology and Microglial Phenotypes in an Amyloidosis Mouse Model

doi: 10.3390/cells12010079

Figure Lengend Snippet: ACI-24 vaccination efficiently reduces Aβ plaque load in APPPS1 mice. Schematic overview of the vaccination paradigm ( A ). ELISA analysis of the anti-Aβ42 total IgG titres (ng/mL) in plasma ( B ). Control APPPS1 mice (PBS treated, in dotted grey) have the baseline titres, while both ACI-24 vaccinated APPPS1 (in red) and ACI-24 vaccinated WT mice (in black) have robust and sustained immune response. Representative images of Aβ (as stained with NAB228 antibody) and nuclei (Hoechst) in cortical sections show decreased Aβ deposition following ACI-24 vaccination. Scale bar for images in the centre column is indicating 200 µm, and scale bar for images in the right column (magnification of dotted boxed regions from centre column images) is indicating 50 µm ( C ). Statistical analysis of 10 control and 10 ACI-24 vaccinated APPPS1 mice for Aβ plaque coverage ( D ), number ( E ) and size ( F ). ACI-24 significantly downregulated Aβ plaque coverage and size. Offspring are from the transgenic mother (pink circles) or father (blue circles). Graphs are presented as mean ± SEM (* p < 0.05, ** p < 0.001, unpaired two-tailed Student’s t -test).

Figure Lengend Snippet: ACI-24 reduces ApoE protein levels and neuronal injury in the offspring generated by the transgenic mother. Representative images of control and ACI-24 vaccinated mice stained for nuclei (Hoechst), fibrillar Aβ (ThR), Aβ plaques (3552 antibody) and ApoE ( A ); and nuclei (Hoechst), fibrillar Aβ (ThR), Aβ plaques (NAB228 antibody) and BACE1 (dystrophic neurites) ( B ). Scale bar: 200 µm. Statistical analysis of 5 control and 6 ACI-24 vaccinated mice (transgenic mother offspring) showing significant downregulation of both total ApoE ( C ) and BACE1 ( D ) coverage. Graphs are presented as mean ± SEM (* p < 0.05, ** p < 0.001, unpaired two-tailed Student’s t -test).
