In addition, could alterations of Ranvier node geometry or of the size of the conducting periaxonal space under the myelin be employed to tune the conduction speed of myelinated axons?
A principal alteracao histopatologica encontrada no sistema nervoso central (SNC) do suino A foi extensa degeneracao Walleriana, representada por vacuolizacao periaxonal e fragmentacao de fibras mielinizadas, e a presenca de alguns macrofagos no interior dos vacuolos, em regioes do tronco encefalico, como coliculo rostral, ponte, obex, e nas porcoes cervical, toracica e lombar da medula espinhal.
Em cortes histologicos de fragmentos de medula espinhal dos dois suinos corados com azul rapido de luxol (ARL) foram evidenciados focos de desmielinizacao moderada a acentuada, nas areas de vacuolizacao periaxonal nos funiculos ventral e lateral da medula espinhal (Figura 1D).
Estes sinais podem ser explicados pela distribuicao das lesoes de vacuolizacao periaxonal no tronco encefalico e medula espinhal.
Anterior spinal nerves showed macrophage infiltration in the periaxonal space, but surrounding myelin sheaths remained almost intact.

47) MAG is a type 1 transmembrane glycoprotein found in periaxonal oligodendrocyte membranes.
Furthermore, experiments with isolated or perfused giant axons have shown that axoplasmic RNA may originate from periaxonal glial cells, thus confirming the concept that a local system of gene expression is endowed to axons.

3]]RNA is synthesized by periaxonal glial cells, thus opening the way to investigations of the mechanisms modulating RNA transfer from glia to axon.
These receptors include two glutamate receptors (NMDA and metabotropic of class H), and a nicotinic ACh autoreceptor, identified on the basis of voltage changes induced in periaxonal glia by neurophysiological stimulation of squid or crayfish giant axons, or by addition of agonists or antagonists of these receptors (7, 8).
