Down-regulation of Aβ in the brain of AD mice by minocycline. Both Aβ42 and Aβ40 levels significantly decreased in the hippocampal and cortex tissues after minocycline treatment (*P<0.01). Values were represented as mean ± SD (n=10). Aβ: beta-amyloid peptides, AD: Alzheimer’s disease, MINO: minocycline.
