Axonal transport and neurodegenerative disease

Biochim Biophys Acta. Nov-Dec 2006;1762(11-12):1094-108. doi: 10.1016/j.bbadis.2006.04.002. Epub 2006 Apr 19.

Abstract

Neurons have extensive processes and communication between those processes and the cell body is crucial to neuronal function and survival. Thus, neurons are uniquely dependent on microtubule based transport. Growing evidence supports the idea that deficits in axonal transport contribute to pathogenesis in multiple neurodegenerative diseases. We describe the motor, cytoskeletal, and adaptor proteins involved in axonal transport and their interactions. Data linking disruption of axonal transport to diseases such as ALS are discussed. Finally, we explore the pathways that may cause neuronal dysfunction and death.
