Deficiencies in complex I subunits of the respiratory chain in Parkinson's disease.
Immunoblotting studies on mitochondria prepared from the striata of patients who died of Parkinson's disease were performed using specific antisera against Complexes I, III and IV. In 4 out of 5 patients with Parkinson's disease, the 30-, 25- and 24-kDa subunits of Complex I were moderately to markedly decreased. No clear difference was noted in immunoblotting studies on subunits of Complexes III and IV between the control and Parkinson's disease. Deficiencies in Complex I subunits seem to be one of the most important clues to elucidate pathogenesis of Parkinson's disease.
