抄録

The electrocyte of the electric organ of the electric eel, Electrophorus electricus, L was investigated by light and electron microscopy as well as immunoelectron microscopy, in order to clarify the fine structures and distribution of cytoskeleton filaments and their relations to proteins, especially desmin and actin. Cytoskeleton-enriched fractions of the electrocytes were analysed with SDS-PAGE. It was verified that a meshwork of filaments was distributed in the electrocytes, more abundantly in the anterior than in the posterior part of the cell, and that this could be associated with membrane invaginations. Desmin and actin were the components of this meshwork, suggesting that desmin intermediate filaments and actin filaments might play a role in the maintenance of the morphology of electrocytes and, as an intracellular filamentous meshwork, they may contribute to the organization of the components of membranes and papillae formation on the anterior face of the electrocytes.
