Structural specializations in cat of chronically demyelinated spinal cord axons as seen in freeze-fracture replicas.

Abstract:

:Axons in chronically demyelinated spinal cord lesions, induced by ethidium bromide injection, display patches of intramembranous particles and indentations resembling nodal and paranodal axolemmal specializations respectively. Both occur in the marginal region of the lesions where the demyelinated axons are intimately associated with astrocytic and oligodendrocytic processes, and probably correspond to the aberrant node-like and paranodal junctional complexes seen in thin sections of this region. Demyelinated axons in the center of the lesion, which are not in contact with glial processes, do not display these membrane specializations.
