“…These glial "shortcut" have been largely described in literature. The internodes SLI's number varies, depending on the species, axonal diameter and physiological conditions (Cajal, 1928, Ghabriel, et al, 1979aand b, 1980aand b, 1981Hiscoe, 1947;MacKenzie et al, 1984;Robertson, 1958,). In the present work SLI have been characterized throughout the molecular expression of cytoskeleton components (actin, tubulin, vimentin) and adhesion molecules (MAG), showing that the SLI cytoplasm have well organized "roads" devoted to traffic.…”
