ATP5F1A and Alzheimer disease: 3.6 A pilot study involving a hippocampus from the postmortem brain of an AD patient with that of a non-AD afflicted individual revealed a greater assembly of ATP5A (complex-V)-associated MCs in the AD hippocampus, whereas assembly of MT-CO2 (complex-IV) and NDUFB8 (complex-I) associated SCs were reduced in the AD hippocampus compared to a non-AD individual
