FIGURE 2.

GluA2 expression in the hippocampus, subiculum, entorhinal cortex, and superior temporal gyrus in human control and Alzheimer's disease cases visualized by 3,3′‐diaminobenzidine‐peroxidase immunohistochemistry. Staining appeared relatively strong within the str. pyramidale of the CA regions (A–D), with an increase in expression within the stratum (str.) moleculare of the dentate gyrus in AD (E1,2). Arrows indicating localization to processes and around pyramidal neurons. CA, cornu ammonis; DG, dentate gyrus; ECx, entorhinal cortex; HP, hippocampus; STG, superior temporal gyrus; str. pyr, stratum pyramidale; str. rad, stratum radiatum; str. gran, stratum granulosum; Sub, subiculum. Scale bars: A1,2 = 1000 µm; B1–E1, B2‐E2 = 100 µm; F1–H1, F2–H2 = 400 µm
