ABSTRACT
The actin cytoskeleton of rod photoreceptors and glial cells in toad retina has been directly viewed using fluorescence microscopy of cells labeled with a potent phallotoxin that specifically binds to F-actin. The three-dimensional organization of this cytoskeletal protein consists of actin filaments, which course through the inner segment and end at the tips of the calycal processes surrounding the base of the outer segment. A transverse layer of actin staining is also observed at the base of rod outer segments in the region where new discs are formed. At the level of the external limiting membrane, evidence has been found for rings of actin within the glial cells that surround the photoreceptors. These actin rings form a structural meshwork in which photoreceptor cells are embedded.
