Mitochondrial function in Parkinson's disease cybrids containing an nt2 neuron-...
Esteves, AR; Domingues, AF; Ferreira, IL; Januário, C; Swerdlow, RH; Oliveira, CR; Cardoso, SMMitochondria likely play a role in Parkinson's disease (PD) neurodegeneration. We modelled PD by creating cytoplasmic hybrid (cybrid) cell lines in which endogenous mitochondrial DNA (mtDNA) from PD or control subject platelets was expressed within human teratocarcinoma (NT2) cells previously depleted of endogenous mtDNA. Complex I activity was reduced in both PD cybrid lines and in the platelet mitochondria us...
Mitochondria dysfunction of Alzheimer's disease cybrids enhances Abeta toxicity
Cardoso, SM; Santana, I; Swerdlow, RH; Oliveira, CRAlzheimer's disease (AD) brain reveals high rates of oxygen consumption and oxidative stress, altered antioxidant defences, increased oxidized polyunsaturated fatty acids, and elevated transition metal ions. Mitochondrial dysfunction in AD is perhaps relevant to these observations, as such may contribute to neurodegenerative cell death through the formation of reactive oxygen species (ROS) and the release of mo...
