Cytoskeletal dynamics and nerve growth

WebGuidance cues regulate the cytoskeleton leading to dynamic changes in growth cone structure and motility. Neurotrophins, such as BDNF, enhance formation and length of growth cone filopodia [ 6, 14 ], which facilitates turning towards a gradient of BDNF [ 13 ]. 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 …
