MTOR and Alzheimer disease: The ratio of phospho‐ and pan‐mTOR levels was upregulated in the AD group compared to the naive group in both the hippocampus and the cerebral cortex (p < 0.01, Figures 5 and 6s), but the AD+PLX group displayed a similar ratio of phospho‐ and pan‐mTOR as the naive group (p > 0.05, Figures 5 and 6s), implying reduced mTOR signaling in both brain regions.
