Mitochondrial Dysfunction Enough to Cause Parkinson’s in Mice

Mitochondrial dysfunction in dopamine-producing brain cells is sufficient to cause Parkinson’s disease, according to a new study done in mice. The study, “Disruption of mitochondrial complex I induces progressive parkinsonism,” was published in Nature. Parkinson’s is caused by the death and dysfunction of dopamine-producing (dopaminergic) neurons. A neuron, or nerve cell, consists of a cell body or soma — the part of the cell that houses its nucleus and DNA — as well as a long,…
