Abstract

Have You Seen...?
Microtubule loss contributes to nervous system degeneration during Alzheimer disease. New findings report that abnormal tau invasion into dendrites, triggered by Amyloid β, results in excess severing of microtubules by spastin. EMBO J 32 : 2920 – 2937 10.1038/emboj.2013.207; published online 09 24 2013 Microtubule loss from axons and dendrites is a key contributor to nervous system degeneration during Alzheimer disease. Previous evidence suggested a simple pathway by which tau dissociation from microtubules in the axon allows excess severing of microtubules by katanin. Now, new evidence has emerged for a more complex pathway by which abnormal tau invasion into dendrites, triggered by A β oligomers, results in excess severing of microtubules by spastin.
