OLE reduces plaque burden in the cortex and hippocampus of TgCRND8 mice.

(A) Representative photomicrographs of Aβ42 immunopositive deposits. (n = 5/group, six sections from each mouse). Insets: high magnification images of representative plaques. Scale bars = 500 µm applies to all reconstructed images and 20 µm to all magnified images. (B) Quantitative analysis of total plaque area and plaque number in untreated and OLE-fed Tg mice (n = 6 for 3.5 and 6 months Tg mice). (C) ELISA: cortical levels of SDS- and formic acid-soluble Aβ40 and Aβ42 peptides in OLE-fed and untreated Tg mice. Both Aβ40 and Aβ42 levels were significantly decreased in OLE-fed Tg versus age-matched untreated Tg (n = 5/group) mice. *P<0.05, **P<0.01 and ***P<0.001. Data are reported as mean values ± S.E.M. mo = month-old.
