Summary

Story summary

Chinese researchers delivered healthy mitochondria into cells by wrapping them in red blood cell membranes, increasing uptake from under 5% to about 80%, as reported in Cell.
In Leigh syndrome mouse models, the approach extended survival by about 20%.
In Parkinson's disease models, the technique restored motor functions and reduced brain cell loss.
Some scientists caution that Parkinson's disease has multifactorial causes, so conclusions about a cure are premature.
