Axonal force, stiffness, and damage as emergent properties of microtubule polymerization, crosslink dynamics, and physical forces
Axonal damage is a critical indicator for traumatic effects of physical impact to the brain. However, the precise mechanisms of axonal damage are still unclear. Here we establish a mechanistic and highly dynamic model of the axon to explore the evolution of damage in response to physical forces. Our axon model consists of a bundle of dynamically polymerizing and depolymerizing microtubules conn...
متن کاملTargeted Ablation of Oligodendrocytes Triggers Axonal Damage
Glial dysfunction has been implicated in a number of neurodegenerative diseases. In this study we investigated the consequences of glial and oligodendrocyte ablation on neuronal integrity and survival in Drosophila and adult mice, respectively. Targeted genetic ablation of glia was achieved in the adult Drosophila nervous system using the GAL80-GAL4 system. In mice, oligodendrocytes were deplet...
متن کاملLife-or-Death Decisions upon Axonal Damage
In this issue of Neuron, Hu et al. (2012) report that upon axonal damage, CHOP and XBP1 unfolded protein response pathways are not recruited equally and have opposite effects on neuronal survival. XBP1 pathway boosting may represent a valuable neuroprotective strategy.
متن کاملAxonal Damage in Pediatric Multiple Sclerosis
Investigators from Georg August University, Gottingen, Germany, analyzed axonal pathology in brain biopsy and autopsy samples from 19 children with early multiple sclerosis (MS).
متن کاملAxonal damage in acute multiple sclerosis lesions.
One of the histological hallmarks of early multiple sclerosis lesions is primary demyelination, with myelin destruction and relative sparing of axons. On the other hand, it is widely accepted that axonal loss occurs in, and is responsible for, the permanent disability characterizing the later chronic progressive stage of the disease. In this study, we have used an antibody against amyloid precu...
