Nucleocytoplasmic transport defects in neurodegeneration - Cause or consequence?

Hutten, Saskia und Dormann, Dorothee (2020): Nucleocytoplasmic transport defects in neurodegeneration - Cause or consequence? In: Seminars in Cell & Developmental Biology, Bd. 99: S. 151-162

Abstract

Defects in nucleocytoplasmic transport have been associated with several neurodegenerative disorders and, in particular, the formation of pathological protein aggregates characteristic for the respective disease. However, whether impaired nucleocytoplasmic transport is a consequence of such aggregates or rather contributes to their formation is still mostly unclear. In this review, we summarize recent findings how both soluble and stationary components of the nucleocytoplasmic transport machinery are altered in neurodegenerative diseases, in particular amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), Alzheimer's disease (AD) and Huntington's disease (HD). We discuss the functional significance of the observed defects for nucleocytoplasmic transport of proteins and mRNAs. Moreover, we highlight interesting parallels observed in physiological ageing and the premature ageing syndrome progeria and propose that they that might provide mechanistic insights also for neurodegenerative processes.
