Wild-type Daniel's strain of Theiler's virus (wt-DA) induces a chronic demyelination in susceptible mice which is similar to multiple sclerosis. A variant of wt-DA (designated DA-P12) generated during the 12th passage of persistent infection of a G26-20 glioma cell line failed to persist and induce demyelination in SJL/J mice. To identify the determinants responsible for this change in phenotyp...

This study examined Schwann cell behavior during paranodal demyelination induced by beta,beta'-iminodipropionitrile (IDPN). The stimuli for Schwann cell proliferation, extensively studied in vitro, are less well understood in vivo. Most in vivo systems previously used to examine Schwann cell proliferation in disease are dominated by loss of internodal myelin sheaths. As used in this study, IDPN...

OBJECTIVE Demyelination is a cardinal feature of multiple sclerosis, but it remains unclear why new lesions form, and whether they can be prevented. Neuropathological evidence suggests that demyelination can occur in the relative absence of lymphocytes, and with distinctive characteristics suggestive of a tissue energy deficit. The objective was to examine an experimental model of the early mul...

multiple sclerosis (ms) is a progressive and autoimmune neurodegenerative disease of the central nervous system (cns). this disease is recognized through symptoms like inflammation, demyelination and the destruction of neurological actions. experimental allergic encephalomyelitis (eae) is a widely accepted animal model for ms. eae is created in animals by injecting the tissue of myelin basic pr...

Introduction . Multiple sclerosis is a chronic immune-mediated disease of the central nervous system with disseminated foci demyelination and progressive neurodegeneration; it most common demyelinating leading cause disability neurological patients young age, characterized by wave-like course alternating periods remission relapse. Currently, there discussion about participation vascular changes...

A major challenge in multiple sclerosis research is to understand the cause or causes of remyelination failure and to devise ways of ameliorating its consequences. This requires appropriate experimental models. Although there are many models of acute demyelination, at present there are few suitable models of chronic demyelination. The taiep rat is a myelin mutant that shows progressive myelin l...

our goal in this paper is to describe and compare basic immunopathologic pattern of common demyelinating disorder, that is very important to choose the best treatment. The most common disorders are multiple sclerosis, neuromyelitis optica,Anti MOG associated disease,ADEM and autoimmune encephalitis. ADEM consists of ‘‘sleeves’’ of demyelination centered on small, engorge...
