Regional mitochondrial respiratory activity in Huntington's disease brain.

Abstract

This study investigated mitochondrial respiratory activity in Huntington's disease (HD) brain. Mitochondrial membranes from caudate and cortex of HD and non-HD autopsied brains were assayed for succinate oxidation, cytochrome oxidase activity, and cytochromes b, cc1, and aa3. There was a significant decrease in HD caudate mitochondrial respiration, cytochrome oxidase activity, and cytochrome aa3, whereas cytochromes b and cc1 were normal. These findings are consistent with the hypothesis that mitochondrial dysfunction may contribute to the localized hypometabolism and progressive atrophy of the HD caudate.
