Independent roles of Rho-GTPases in growth cone and axonal behavior

Publikováno v: Journal of Neurobiology. 54:358-369

Many external signals influence growth cone motility, pathfinding, and the formation of synapses that lead to the final map formation of the retinotectal system. Chick temporal retinal ganglion cell axons (RGCs) collapse and retract after encounterin

Thrombin action decreases acetylcholine receptor aggregate number and stability in cultured mouse myotubes

Autor: Phillip G. Nelson, Roger W. Davenport, Eric R. Snyder, Sunghee Kim, Maria A. Lanuza, Min Jia

Publikováno v: Developmental Brain Research. 122:119-123

Neurons develop and make very stable, long-term synaptic connections with other nerve cells and with muscle. Synaptic stability at the neuromuscular junction changes over development in that a proliferation of synaptic input are made to individual my

Protein kinase C-mediated changes in synaptic efficacy at the neuromuscular junction in vitro: The role of postsynaptic acetylcholine receptors

Autor: Roger W. Davenport, Veronica Dunlap, Min Jia, Min-Xu Li, Phillip G. Nelson, Maria A. Lanuza, Sunghee Kim

Publikováno v: Journal of Neuroscience Research. 61:616-625

Activation of a mouse in vitro neuromuscular synapse produces a reduction in synaptic efficacy which is greater for nonactivated than for activated inputs to the myotubes. This has been shown to require thrombin and thrombin receptor activation and t

Cellular Localization of Ephrin-A2, Ephrin-A5, and Other Functional Guidance Cues Underlies Retinotopic Development across Species

Autor: Edda Thies, Phillip G. Nelson, Renping Zhou, Roger W. Davenport

Publikováno v: The Journal of Neuroscience. 18:975-986

Avian retinotectal and rodent retinocollicular systems are general model systems used to examine developmental processes that underpin topographically organized neuronal circuits. The two systems rely on guidance components to establish their precise

Distinct calcium signaling within neuronal growth cones and filopodia

Autor: Linda R. Mills, Stanley B. Kater, Ping Dou, Roger W. Davenport

Publikováno v: Journal of Neurobiology. 31:1-15

Previous findings indicate that spatial restriction of intracellular calcium levels within growth cones can regulate growth cone behavior at many levels, ranging from filopodial disposition to neurite extension. By combining techniques for focal stim

Branching Morphogenesis in Vertebrate Neurons

Autor: Roger W. Davenport, Katherine M. Kollins

Publikováno v: Branching Morphogenesis ISBN: 9780387256153

Within the developing vertebrate nervous system, strict control of branching morphogenesis is essential for establishing appropriate circuitry, since the geometry of neuronal arbors critically influences their functional properties. Thus, identificat

Neuronal growth cone collapse triggers lateral extensions along trailing axons

Autor: Edda Thies, Matt Cohen, Roger W. Davenport

Publikováno v: Nature neuroscience. 2(3)

Axonal outgrowth is generally thought to be controlled by direct interaction of the lead growth cone with guidance cues, and, in trailing axons, by fasciculation with pioneer fibers. Responses of axons and growth cones were examined as cultured retin

Response of retinal ganglion cell axons to striped linear gradients of repellent guidance molecules

Autor: Roger W. Davenport, Stephan M. Rosentreter, Julita Huf, Friedrich Bonhoeffer, Jürgen Jung, Jürgen Löschinger

Publikováno v: Journal of neurobiology. 37(4)

Although molecular gradients have long been postulated to play a role in the development of topographic projections in the nervous system, relatively little is known about how axons evaluate gradients. Do growth cones respond to concentration or to s

Functional guidance components and their cellular distribution in retinotectal co-cultures

Autor: Roger W. Davenport

Publikováno v: Cell and tissue research. 290(2)

Recent advances in the study of the developmental processes that direct afferent axons toward their final destinations are beginning to elucidate the cellular and molecular bases for the early development of retinotectal topography. The present revie
