Somatic instability of the C9orf72 repeat expansion in blood differs between patients with amyotrophic lateral sclerosis or frontotemporal dementia.

Mathieu Barbier, Mounir Ichalalen, Maria del Mar Amador…·Isabelle Le Ber

This study uses optical genome mapping to analyze C9orf72 repeat expansion instability in blood from ALS and FTD patients, finding age-dependent differences in repeat size dynamics between conditions.

Large extracellular vesicles containing mitochondria (EVMs) derived from Alzheimer disease cells harbor pathologic functional and molecular profiles and spread mitochondrial dysfunctions

Fanny Eysert, Véronique Legros, Anne-Sophie Gay…·Mounia Chami

This study characterizes large extracellular vesicles containing mitochondria (EVMs) from Alzheimer's Disease cells, showing they carry pathological mitochondrial dysfunction and spread it to recipient cells.
