Fig. 8From: Prophylactic melatonin significantly reduces Alzheimer’s neuropathology and associated cognitive deficits independent of antioxidant pathways in AβPPswe/PS1 miceELISA measurement of plasma Aβ1–40 and Aβ1–42 levels in 9-month-old and 14-month-old 2xAD mice. In all cases, MEL tended to lower amyloid peptide levels. A significant effect of MEL was seen at 14 months for Aβ1–42 levels in both MTNR+ mice (p = 0.0043) and in MTNR- mice (p = 0.011). Evaluated with 2-way ANOVA; n = 3–5; error bars represent SEMBack to article page
