摘要

Frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS) are fatal, co-occurring neurodegenerative disorders. Dysregulation of mRNA metabolism, transport, and local translation is a significant mechanism contributing to FTD/ALS. Here, we review the processes of neuronal RNA transport and translation, their disruption in FTD/ALS, and mechanistic interplay between the two. Finally, we discuss current progress targeting transport and translation defects and identify potential future directions for therapeutic development.
