Aβ plaques and vascular deposits in AD-inoculated mouse lemurs. Parenchymal diffuse a-b and dense c-d plaques stained by 4G8 or Aβ42 antibodies in AD-brain inoculated mouse lemurs. Plaques were also Thioflavin S-positive e–f. Cerebral Aβ angiopathy was also observed in cortical regions g and in the hippocampus h (4G8 antibody). Scale bars: 20 µm in a-d, f, h; 40 µm in e; 50 µm in g
