A. Western blots of total entorhinal cortex homogenates in AD cases stages I/II and controls incubated with antibodies to ATP‐synthase α subunit. Antibodies to actin were used as a control of protein loading. No significant differences in the expression levels were seen between the two groups (Student's t‐test, P = 0.6). B. Complex V (ATP‐synthase) activity (% respect control group), normalized for citrate synthase activity, was significantly decreased in AD Braak stages I/II group (P = 0.02). No differences between control and AD Braak stages I/II groups were detected for mitochondrial complex I activity (P = 0.41). Abbreviations: AD = Alzheimer's disease; ATP = ATP‐synthase.
