title: Isolation and sequence analysis of two intermediate filament cDNA clones from fish optic nerve.
abstract: The high post-traumatic regenerative ability of fish central nervous system has been partially attributed to the hospitable nature of the surrounding non-neuronal cells and their appropriate response to injury. Uncovering the correlation between fish non-neuronal cell structure and behavior might yield a better understanding of what makes them supportive to axonal growth. Towards this goal, structural proteins expressed by fish non-neuronal cells need to be characterized. In the present study we isolated cDNA clones encoding fish intermediate filaments which are prominent structural proteins in astrocytes. Among the isolated clones, one was identified as fish vimentin and another was found identical to the cloned fish keratin 8. Results are discussed with respect to the use of these cDNAs for further understanding of fish non-neuronal cell plasticity.
