Growth cone cytoskeleton

WebIn the developing nervous system, axons are guided to their synaptic targets by motile structures at the axon tip called growth cones, which reorganize their cytoskeleton in order to steer in response to chemotactic cues. Growth cone motility is mediated by an actin-adhesion “clutch” mechanism, in which mechanical attachment to a substrate, … WebMar 1, 2011 · During development, much of the communication that occurs between environmental guidance cues and the cytoskeleton takes place at the growing tip of the …

WebGrowth cones facilitate axon growth and guidance by bundling and extending actin filaments into structures known as filopodia and microspikes. Binding of filopodia and adhesion receptors to particular … WebFor the establishment of neuronal circuits, axons of developing neurons are directed by guidance cues to their correct destinations. The growth cone is located at the tip of the outgrowing axon and senses guidance cues in the environment and translates this information into changes in the cytoskeleton, thereby determining the direction of …

WebMay 25, 2007 · Dynamic polarization of the growth cone cytoskeleton underlies chemotropism and galvanotropism: Extending microfilaments predominate on the side of the growth cone nearest to a chemoattractant source, whereas localized collapse of the actin cytoskeleton occurs near a repellent stimulus (18, 19).

WebIn the growth cone, many intracellular signaling pathways that are activated by guidance cues converge on the growth cone cytoskeleton and regulate its dynamics. Most of the research effort in this area has focussed on the actin, microfilament cytoskeleton of the growth cone, principally because it underlies growth cone motility, the extension ...
