Mining Gene Ontology Data with AGENDA
The Gene Ontology (GO) initiative is a collaborative effort that uses controlled vocabularies for annotating genetic information. We here present AGENDA ( A pplication for mining Gen e Ontology Da ta), a novel web-based tool for accessing the GO database.

Effect of beta-Dystroglycan Processing on Utrophin / DP116 Anchorage in Normal and MDX Mouse Schwann Cell Membrane [PDF]
In the peripheral nervous system, utrophin and the short dystrophin isoform (Dp116) are co-localized at the outermost layer of the myelin sheath of nerve fibers; together with the dystroglycan complex. In peripheral nerve, matrix metalloproteinase (MMP) creates a 30 kDa fragment of beta-dystroglycan, leading to a disruption of the link between the ...

Enhanced mechanical heterogeneity of cell collectives due to temporal fluctuations in cell elasticity [PDF]
Cells are dynamic systems characterized by temporal variations in biophysical properties such as stiffness and contractility. Recent studies show that the recruitment and release of actin filaments into and out of the cell cortex - a network of proteins underneath the cell membrane - leads to cell stiffening prior to division and softening immediately ...

Control of Schwann cell myelination [PDF]
Schwann cells ensheath all axons of peripheral nerves. Only around large-diameter axons do they elaborate myelin, forming insulating sheaths that are vital for fast conduction of axon potentials. A series of recent papers has illuminated some of the ways in which the process of myelination is controlled, both by signals from axons and by positive and ...

Schwann Cell Myelination [PDF]
Myelinated nerve fibers are essential for the rapid propagation of action potentials by saltatory conduction. They form as the result of reciprocal interactions between axons and Schwann cells. Extrinsic signals from the axon, and the extracellular matrix, drive Schwann cells to adopt a myelinating fate, whereas myelination reorganizes the axon for its

Rab27a/Slp2-a complex is involved in Schwann cell myelination
Myelination of Schwann cells in the peripheral nervous system is an intricate process involving myelin protein trafficking. Recently, the role and mechanism of the endosomal/lysosomal system in myelin formation were emphasized.

The Neurobiology of Schwann Cells
This selective review of Schwann cell biology focuses on questions relating to the origins, development and differentiation of Schwann cells and the signals that control these processes. The importance of neuregulins and their receptors in controlling Schwann cell precursor survival and generation of Schwann cells, and the role of these molecules in ...

Embryonic Corneal Schwann Cells Express Some Schwann Cell Marker mRNAs, but No Mature Schwann Cell Marker Proteins [PDF]
Embryonic chick nerves encircle the cornea in pericorneal tissue until embryonic day (E)9, then penetrate the anterior corneal stroma, invade the epithelium, and branch over the corneal surface through E20. Adult corneal nerves, cut during transplantation or LASIK, never fully regenerate.

Transcriptional Regulation Induced by cAMP Elevation in Mouse Schwann Cells
In peripheral nerves, Schwann cell development is regulated by a variety of signals. Some of the aspects of Schwann cell differentiation can be reproduced in vitro in response to forskolin, an adenylyl cyclase activator elevating intracellular cAMP ...

Hydrogen peroxide is a neuronal alarmin that triggers specific RNAs, local translation of Annexin A2, and cytoskeletal remodeling in Schwann cells [PDF]
Schwann cells are key players in neuro-regeneration: They sense "alarm" signals released by degenerating nerve terminals and differentiate toward a proregenerative phenotype, with phagocytosis of nerve debris and nerve guidance.
