  abstract  = {Neurotrophic factor signaling modulates differentiation, axon growth and maintenance, synaptic plasticity and regeneration of neurons after injury. Ciliary neurotrophic factor (CNTF), a Schwann cell derived neurotrophic factor, has an exclusive role in axon maintenance, sprouting and synaptic preservation. CNTF, but not GDNF, has been shown to alleviate motoneuron degeneration in pmn mutant mice carrying a missense mutation in Tbce gene, a model for Amyotrophic Lateral Sclerosis (ALS). This current study elucidates the distinct signaling mechanism by which CNTF rescues the axonal degeneration in pmn mutant mice. ...},

  abstract  = {In neurons, microtubules form a dense array within axons, and the stability and function of this microtubule network is modulated by neurofilaments. Accumulation of neurofilaments has been observed in several forms of neurodegenerative diseases, but the mechanisms how elevated neurofilament levels destabilize axons are unknown so far. Here, we show that increased neurofilament expression in motor nerves of pmn mutant mice, a model of motoneuron disease, causes disturbed microtubule dynamics. The disease is caused by a point mutation in the tubulin-specific chaperone E (Tbce) gene, leading to an exchange of the most C-terminal amino acid tryptophan to glycine. As a consequence, the TBCE protein becomes instable which then results in destabilization of axonal microtubules and defects in axonal transport, in particular in motoneurons. Depletion of neurofilament increases the number and regrowth of microtubules in pmn mutant motoneurons and restores axon elongation. This effect is mediated by interaction of neurofilament with the stathmin complex. Accumulating neurofilaments associate with stathmin in axons of pmn mutant motoneurons. Depletion of neurofilament by Nefl knockout increases Stat3-stathmin interaction and stabilizes the microtubules in pmn mutant motoneurons. Consequently, counteracting enhanced neurofilament expression improves axonal maintenance and prolongs survival of pmn mutant mice. We propose that this mechanism could also be relevant for other neurodegenerative diseases in which neurofilament accumulation and loss of microtubules are prominent features.},
