Cause Of Aging
From Better Humans an article on the mitochondria, the portion of cells that Huntington's Disease most affects.
"Mitochondria convert energy from food to ATP, which cells use for power.
They have their own DNA, called mitochondrial DNA, and researchers have hypothesized that mutations in this contribute to aging by interfering with how cells generate energy.
Previous research has shown that defects in mitochondrial DNA accumulate with age, but it wasn't clear whether such defects were a cause or a symptom of aging.
"What we have now is this clear-cut cause-and-effect relationship," Larsson said in an interview. "It will provide a completely new angle to treat aging-related problems."
