β-amyloid pathology is reduced in Aβ1–42-immunized PSAPP mice heterozygous for CD40. Mouse coronal brain sections were embedded in paraffin and stained with monoclonal human Aβ antibody (A), or were stained with congo red (B), and the hippocampus is shown. (C) Percentages [plaque area/total area; mean ± SD with n = 16 mice (8♂/8♀)] of Aβ antibody-immunoreactive Aβ plaques (top panel) and congo red-positive Aβ deposits (bottom panel) were calculated by quantitative image analysis for each brain region (CC/H: cingulate cortex and hippocampus; EC: entorhinal cortex) as indicated.
