Syntaxin 5 Overexpression and β-Amyloid 1–42 Accumulation in Endoplasmic Reticulum of Hippocampal Cells in Rat Brain Induced by Ozone Exposure

Figure 1

Triple IF to detect beta-amyloid 1–42 in the ER. Five micrometer-thick brain tissue sections form the hippocampi of the control group (CTRL) and the rats exposed to O3 (0.025 ppm) for 3 months (3 M) are shown. Goat anti-GRP78 was used as ER marker. Rabbit anti-βA42 is shown in green and GRP78 in red. DAPI staining and merge between the red, green, and blue channels are shown (MERGE). The arrows indicate the intracellular βA42 deposition and colocalization in ER. There was no βA42 detection at 7, 15, 30, and 60 days of treatment (data not shown).
