ACE2 activator diminazene aceturate ameliorates Alzheimer's disease-like neuropathology and rescues cognitive impairment in SAMP8 mice


Figure 5. DIZE alleviated synaptic and neuronal losses in the brain of SAMP8 mice. (A) The protein levels of synaptophysin in the brain were detected by western blot. β-actin was used as a loading control. (B) Quantitative analysis of synaptophysin protein levels. Data were expressed as a fold change relative to the age-matched vehicle-treated SAMR1 control mice. (C) Neuronal loss in the parietal cortex of mice were detected by Nissl staining. Neurons with dark violet nucleus and intact morphology were identified as Nissl-positive neurons. Scale bar=100 μm. (D) Quantitative analysis of Nissl-positive neurons in the brain. Data were analyzed by one-way ANOVA followed by Tukey’s post hoc test. Columns represent mean ± SD (n=8 per group). *P<0.05 versus age-matched vehicle-treated SAMR1 control mice. #P<0.05 versus vehicle-treated SAMP8 mice.
