Inositol 1,4,5-Trisphosphate Receptor Type 3 Regulates Neuronal Growth Cone Sensitivity to Guidance Signals

open access: yesiScience, 2020
Summary: During neurodevelopment, the growth cone deciphers directional information from extracellular guidance cues presented as shallow concentration gradients via signal amplification.

Application of Chondroitin Sulfate Derivatives for Understanding Axonal Guidance in the Nervous System during Development [PDF]

open access: yes, 2013
Neuronal axons and their growth cones recognize molecular guidance cues within the local environment, forming axonal pathways to produce precise neuronal networks during nervous system development.

High level sill and dyke intrusions initiated from rapidly buried mafic lava flows in scoria cones of Tongoa, Vanuatu (New Hebrides), South Pacific [PDF]

open access: yes, 2006
Scoria cones are generally considered to grow rapidly in days to weeks or months. During their growth lava flows may be fed onto the cone surface from lava-lake breaches, or form by coalescence of spatter; such flows are preserved interbedded with scoria

Microtechnologies for studying the role of mechanics in axon growth and guidance

open access: yesFrontiers in Cellular Neuroscience, 2015
The guidance of axons to their proper targets is not only a crucial event in neurodevelopment, but also a potential therapeutic target for neural repair.

Tissue-nonspecific alkaline phosphatase promotes axonal growth of hippocampal neurons [PDF]

open access: yes, 2011
Axonal growth is essential for establishing neuronal circuits during brain development and for regenerative processes in the adult brain. Unfortunately, the extracellular signals controlling axonal growth are poorly understood.

Tyrosine kinase inhibition produces specific alterations in axon guidance in the grasshopper embryo [PDF]

open access: yes, 1998
Tyrosine kinase signaling pathways are essential for process outgrowth and guidance during nervous system development. We have examined the roles of tyrosine kinase activity in programming growth cone guidance decisions in an intact nervous system in ...

The nonuniqueness of the tangent cones at infinity of Ricci-flat manifolds

open access: yes, 2016
It is shown by Colding and Minicozzi the uniqueness of the tangent cone at infinity of Ricci-flat manifolds with Euclidean volume growth which has at least one tangent cone at infinity with a smooth cross section.

The SH2/SH3 Adaptor Protein Dock Interacts with the Ste20-like Kinase Misshapen in Controlling Growth Cone Motility [PDF]

open access: yes, 1999
Recent studies suggest that the SH2/SH3 adaptor Dock/Nck transduces tyrosine phosphorylation signals to the actin cytoskeleton in regulating growth cone motility.
