Photomicrographs of ERC lesion effects on Aβ deposits in the dentate gyrus. A, B, Sections through the hippocampus of a Tg mouse with sham surgery (A) and a Tg mouse with ERC ablation (B) stained with Aβ4G8. A1,A2, B1, and B2 represent magnifications of the demarcated areas in A andB. There is strong Aβ immunoreactivity in the form of plaques in dentate gyrus and the CA3 field. Note the decreased Aβ load in the dentate gyrus (especially in the molecular layer of dentate gyrus) on the side ipsilateral to lesion (B1) compared with the side contralateral to lesion (B2) and sham (A1, A2). MDG, Molecular layer of dentate gyrus; PoDG, polymorph layer of dentate gyrus. Scale bars: A, B, 800 μm;A1, A2, B1,B2, 100 μm.
