Glial cell biology in Drosophila and vertebrates.

abstract：:It has become apparent in recent years that the cytoskeleton and its associated proteins play a major role in secretion. This review summarizes recent findings on the cytoskeleton organization and the molecular topology of its regulatory proteins, as well as the dynamic changes that occur in this organelle during secr...
