Morphological And Physiological Examination Of A Demyelinating And Remyelinating Lesion, Paul Anson Felts

Theses and Dissertations in Biomedical Sciences

Multiple sclerosis causes demyelination of central nerve fibers, and it is this pathology which results in most of the symptoms of the disease. The repair of the fibers by remyelination has been advanced as a potential symptomatic therapy, but at present the conduction properties of remyelinated central fibers are not well understood. In this study the conduction properties of Schwannian or oligodendrocyte remyelinated central nerve fibers have been determined. In addition, the status of the blood-brain barrier has been examined in lesions characterized by Schwann cell remyelination. These lesions chronically lack astrocytes, a cell believed to be involved in the …
