Growth cone collapse
Did you know?
A growth cone is a large actin-supported extension of a developing or regenerating neurite seeking its synaptic target. It is the growth cone that drives axon growth. Their existence was originally proposed by Spanish histologist Santiago Ramón y Cajal based upon stationary images he observed under … See more The morphology of the growth cone can be easily described by using the hand as an analogy. The fine extensions of the growth cone are pointed filopodia known as microspikes. The filopodia are like the "fingers" of the … See more Movement of the axons is controlled by an integration of its sensory and motor function (described above) which is established through second messengers such as calcium and cyclic nucleotides. The sensory function of axons is dependent on cues … See more The highly dynamic nature of growth cones allows them to respond to the surrounding environment by rapidly changing direction and branching in response to various … See more WebApparently, the consolidation of the base of the growth cone into the elongating neurite shaft, with the resulting collapse of the relatively flat growth cone into a more cylindrical structure surrounding microtubule bundles in the shaft, is required if the growth cone is to advance further.
WebMay 17, 2013 · Growth cone collapse is an easy and efficient test for detecting and characterizing axon guidance activities secreted or expressed by cells. It can also be used to dissect signaling pathways by ... WebJul 17, 2014 · In this study we used intracellular calcium imaging to figure out whether Sema3A-induced growth cone collapse is a Ca2+dependent process. Intracellular Ca2+imaging results using Fura-2 AM showed Ca2+increase in E15 mice dorsal root ganglia neurons upon Sema3A treatment.
WebMay 1, 1993 · What is growth-cone collapse? The structure of the growth cone is supported internally by the cytoskeleton. In the filopodia and lamellipodia, which constitute the periphery of the growth cone, this is predominantly composed of actin. WebSep 21, 2010 · For example, it induces growth cone collapse in primary hippocampal neurons[22, 23], but stimulates axonal outgrowth of embryonic dorsal root ganglion neurons and guides the migratory process of gonadotropin hormone-releasing hormone-1 cells. Contradictory to its interaction with CD72 in the immune system, Sema4D interacts with …
WebJan 1, 1993 · The signaling mechanism is unknown. In culture, growth cone collapse can be caused by solubilized embryonic brain membranes, central nervous system myelin, a 35-kilodalton protein isolated from myelin, and mastoparan. Collapse induced by each of these is blocked by pertussis toxin.
