Cytoskeleton dynamics in axon regeneration
Recent years have seen cytoskeleton dynamics emerging as a key player in axon regeneration. The cytoskeleton, in particular microtubules and actin, ensures the growth of neuronal processes and maintains the singular, highly polarized shape of neurons. Following injury, adult central axons are tipped by a dystrophic structure, the retraction bulb, which prevents their regeneration. Abnormal cyto...
متن کاملAxon regeneration in C. elegans.
Single axon transection by laser surgery has made Caenorhabditis elegans a new model for axon regeneration. Multiple conserved molecular signaling modules have been discovered through powerful genetic screening. In vivo imaging with single cell and axon resolution has revealed unprecedented cellular dynamics in regenerating axons. Information from C. elegans has greatly expanded our knowledge o...
متن کاملGuidance molecules in axon regeneration.
The regenerative capacity of injured adult mammalian central nervous system (CNS) tissue is very limited. Disease or injury that causes destruction or damage to neuronal networks typically results in permanent neurological deficits. Injury to the spinal cord, for example, interrupts vital ascending and descending fiber tracts of spinally projecting neurons. Because neuronal structures located p...
متن کاملInflammation and axon regeneration.
PURPOSE OF REVIEW The inflammatory response that accompanies neural injury involves multiple cell types and effector molecules with both positive and negative effects. Inflammation is essential for normal regeneration in the peripheral nervous system, and here we review evidence that augmenting inflammation can enhance regeneration in areas of the central nervous system in which it normally doe...
متن کاملNogo and axon regeneration.
Nogo-A is one of several neurite growth inhibitory components present in oligodendrocytes and CNS myelin membranes. Nogo has a crucial role in restricting axonal regeneration and compensatory fibre growth in the injured adult mammalian CNS. Recent studies have shown that in vivo applications of Nogo neutralizing antibodies, peptides blocking the Nogo receptor subunit NgR, or blockers of the pos...
