The chain of events in AD cybrids. Altered COX function in AD cybrids presumably arises from and reflects mtDNA differences between the AD and control subjects that provided each cell line's mtDNA. Because mtDNA only encodes components of the respiratory chain, all other unique biochemical and molecular changes that occur in a cybrid line are consequences of its mtDNA-determined respiratory chain function.
