Mitochondrial and axonal abnormalities precede disruption of the neurofilament network in a model of charcot-marie-tooth disease type 2E and are prevented by heat shock proteins in a mutant-specific fashion.

Abstract excerpt

Mutations in NEFL encoding the light neurofilament subunit (NFL) cause Charcot-Marie-Tooth disease type 2E (CMT2E), which affects both motor and sensory neurons. We expressed the disease-causing mutants NFL and NFL in motor neurons of dissociated spinal cord-dorsal root ganglia and demonstrated that they are incorporated into the preexisting neurofilament network but eventually disrupt neurofilaments without...
