Abstract:
Objective To investigate the expression pattern and possible function of Nogo-A during neuronal growth. Methods E18 rat hippocampal neurons were primarily cultured both in high-density and low-density conditions. Immunohistochemistry and Western blot were performed to detect Nogo-A expression and distributional changes. Results Nogo-A was found in hippocampal neurons, mainly located in the cytoplasm, plasma membrane and neurites. It was detected at the proximal part of all neurites before axon formation. In axons, Nogo-A was enriched in the distal segment and axonal growth cone. In mature neurons, the fiber net work displayed a large number of Nogo-A immunoreactive varicosities. Conclusion The present results indicate that the neuronal Nogo-A may be involved in the process of neurite outgrowth and axonal projection.
