  • ADVANCEMENT OF CYTOSKELETON AND AXON OUTGROWTH OF NEURON

    Object ive To summa r i z e the advanc ement of cytoske l e ton and axon outgrowth of neuron. Methods The recent l iterature concerning cytoskeleton and axon outgrowth of neuron was reviewed and summarized. Results The actin filaments and microtubules in neuron were highly polarized and dynamic structures confined to the ti ps of axons and the reci procal interactions between these two major cytoskeletal polymers was also dynamic. Attractive or a repulsive cue whose final common path of action was the growth cone cytoskeleton mediated the growth of axons of neuron by intracellular signaling cascades. Regulating the actin filament and microtubule dynamics as well as their interactions in growth cones played a key role in neurite outgrowth and axon guidance. Rho-GTPases and glycogen synthase kinase 3β (GSK-3β), the two major intracellular signal ing pathways had emerged in recent years as candidates for regulating the dynamics of actin filaments and microtubules. Conclusion The axon outgrowth and guidance depend on well-coordinated cytoskeletal and reciprocal interaction dynamics which also mediate axon regeneration after spinal cord injury. Regulating activity of Rho-GTPases and GSK- 3β simultaneously may acts as key role to regulate the dynamics of cytoskeletal and to determine axon outgrowth.
