Plant GlcCer attenuates inflammation and cognitive impairment in APP mice. (a) Levels of proinflammatory cytokines in the cerebral cortices of APP mice administered purified GlcCer or vehicle were measured by ELISA (n = 10 animals, 6 males and 4 females, each group). (b) Representative hippocampal sections of GlcCer- or vehicle-treated APP mice stained with antibody against synaptophysin. Scale bars, 100 µm. (c) Densities of synaptophysin-positive presynaptic terminals in the hippocampal sections (two sections/mouse, five mice, 3 males and 2 females, per group). Spontaneous alternation (d) and numbers of arm entries (e) of GlcCer- and vehicle-treated APP mice (n = 15 animals, 8 males and 7 females, each) and age-matched wild-type mice (n = 5, all males) in the Y-maze to evaluate spatial memory. The data represent the means ± SDs. ns, not significant; *P < 0.05 by t tests.
