Unconventional Fibrillar Structures in the Cytoplasm
Besides the classical three groups of cytoskeletal structures, a number of other fibrillar elements have been described in the cytoplasm. These structures have not yet been well explored. Some of them have been seen only in the cells of a few types of lower eukaryotes. Even the existence of some of these structures is still controversial. Nevertheless, it is possible that future studies will show that at least some of these fibrils are not artifacts or exotic rarities, but are important and common components of the cytoskeleton. Therefore, the data on these structures deserve attention.
