Disruption of axonal transport in neurodegeneration

SH Berth, TE Lloyd - The Journal of Clinical Investigation, 2023 - Am Soc Clin Investig
Neurons are markedly compartmentalized, which makes them reliant on axonal transport to
maintain their health. Axonal transport is important for anterograde delivery of newly …

LRRK2 phosphorylation of Rab GTPases in Parkinson's disease

Dynein and dynactin move long-range but are delivered separately to the axon tip

AD Fellows, M Bruntraeger, T Burgold… - Journal of Cell …, 2024 - rupress.org
Axonal transport is essential for neuronal survival. This is driven by microtubule motors
including dynein, which transports cargo from the axon tip back to the cell body. This …

Regulatory imbalance between LRRK2 kinase, PPM1H phosphatase, and ARF6 GTPase disrupts the axonal transport of autophagosomes

D Dou, EM Smith, CS Evans, CA Boecker… - Cell reports, 2023 - cell.com
Gain-of-function mutations in the LRRK2 gene cause Parkinson's disease (PD), increasing
phosphorylation of RAB GTPases through hyperactive kinase activity. We find that LRRK2 …
