Quantitative analyses of the co-localization between calretinin-immunoreactive neurons and hAPP-expressing interneurons in hippocampus of Tg2576 mice. Typical examples of double labelings in stratum radiatum are shown in panel (A). White arrows point to double-labeled neurons, green, and red arrows to neurons that are only labeled by green (calretinin) and red (hAPP) fluorescence, respectively. Quantitative analysis revealed that of all hAPP transgene-expressing interneurons 4% (in stratum moleculare) to 18% (in DG hilus) were calretinin-immunoreactive (B). Of all calretinin-expressing neurons, 18 to 38% expressed the hAPP transgene in defined hippocampal layers (C).
