Fig. 5From: Neuropathology changed by 3- and 6-months low-level PM2.5 inhalation exposure in spontaneously hypertensive ratsExpressions of total (t)-tau and phosphorylated (p)-tau in the olfactory bulb, cerebellum, hippocampus, and cortex after 3 and 6 months of exposure to particulate matter with an aerodynamic diameter of < 2.5 μm (PM2.5; exposure group). Three months of exposure to PM2.5 caused significant expressions of t-tau and p-tau in the olfactory bulb compared to the control (high-efficiency particulate air; HEPA). * p < 0.05Back to article page
