Fig. 7From: Melatonin ameliorates tau-related pathology via the miR-504-3p and CDK5 axis in Alzheimer’s diseaseMelatonin decreases neuronal loss. The expression of NeuN was assessed to measure the number of neurons in the hippocampi of 13-month-old WT (n = 8), hTau + SA (n = 5) and hTau + MT mice (n = 5) (a). The CA1 (b), CA3 (c) and DG (d) regions of the hippocampus are shown. Scale bars, 100 μm. Data are presented as the means ± standard errors (*P < 0.05, **P < 0.01)Back to article page
