Third, two classes of molecular inhibitors to growth are present in the lesioned CNS to actively block axonal growth: inhibitory extracellular matrix proteins, including chondroitin sulfate proteoglycans, and inhibitory proteins present on adult myelin, including Nogo, myelin-associated glycoprotein, oligodendrocyte-myelin glycoprotein, netrin
, semaphorins, Wnt proteins, and others [64-66].
Soluble adenylyl cyclase responds to both extracellular (tumor necrosis factor, netrin
, nerve growth factor) and intracellular (bicarbonate, pH, calcium) signals.
He says that the latest set of findings suggest that integrin helps the anchor cell orient itself toward the basement membranes, and that it also directs netrin
to build the puncta in the proper place to ease an opening through.
The Robo receptor is responsive to the repellent protein, slit, also expressed by the midline, but not netrin (Kidd, Bland, & Goodman, 1999; Stein & Tessier-Lavigne, 2001).
Ephrin Inhibitory and Diffusible protein: A5 and A2; mammals attractant diffusible secreted to work have 8 ephrins and 13 proteins; ephrin A5: locally, as a gradient Eph receptors branching of axons to work long distance, or membrane bound GAP-43 Assist in critical Amplify environmental decisions signals Glial cells or glial Scaffold trophic Secretion of midline wedge support attractants and CAMS Laminin Trophic alone and Diffusible protein inhibitory when combined with Netrin-1 Netrins Midline attractant Diffusible protein; alone and inhibitory secreted when combined with laminin Neurotrophin family, Neuronal survival, Released from target i.
Hierarchical organization of guidance receptors: Silencing of netrin attraction by slit through a Robo/DCC receptor complex.
But other axons grow away from netrin, he reports this week at the Society for Neuroscience meeting held in Miami.
Thus, like netrins, collapsin molecules may represent a family of molecules whose unknown number of members have similar structures and functions, Raper notes.
The team purified the two netrin proteins from 25,000 embryonic chick brains and obtained a partial amino acid sequence of the proteins.
The discovery of the netrins reinforced Ramon y Cajal's early theory by isolating two of the postulated chemical attractants that direct movement and growth of axons in the spine.
