Macrophages then invade from the nodes into the periaxonal space, scavenging the injured axons.
MAG, another MAI [52,72, 73], is a minor component of mature, compact myelin, enriched in the periaxonal membrane of the myelin sheath and is expressed by oligodendrocytes and Schwann cells.
Macrophages infiltrate into the periaxonal space between SC axolemma and the axon, leaving the myelin sheath intact [72].
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.
MAG is found on the periaxonal loop and paranodal loops of myelin and functions both as a ligand for an axonal receptor (a sialylated glycoconjugate, probably a ganglioside [66, 67]), that is needed for the maintenance of myelinated axons, and as a receptor for an axonal signal that promotes the differentiation, maintenance, and survival of oligodendrocytes [68].
Anterior spinal nerves showed macrophage infiltration in the periaxonal space, but surrounding myelin sheaths remained almost intact.

Moreover, a bacterial ganglioside-like epitope stimulates B cells to induce antibodies that opsonize cross-reactive axolemmal antigens, fix complement and target macrophages to invade the periaxonal space, block conduction, or cause axonal degeneration.
(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.
