| 摘要 |
Nogo receptor 1 (NgR1) is a leucine rich repeat protein that forms part of a signaling complex that modulates axon regeneration. Previous studies have shown that the entire LRR region of Nogo receptor-1, including the C-terminal cap of LRR, LRRCT, is needed for ligand binding, and that the adjacent CT stalk of the Nogo receptor-1 contributes to interaction with its co-receptors. The present invention is directed to the use of certain Nogo receptor-1 and Nogo receptor-2 polypeptides and polypeptide fragments for promoting neurite outgrowth, neuronal survival, and axonal regeneration in CNS neurons. The invention features molecules and methods useful for inhibiting neurite outgrowth inhibition, promoting neuronal survival, and/or promoting axonal regeneration in CNS neurons.
