Washington University Experience | MYELIN (IMMUNE-MEDIATED) | MS - Chronic Active Plaque | 2E12 Multiple Sclerosis (Case 2) Chronic Active Plaque, inactive area LFB-PAS 1 20X

This image is taken from the inactive region stained for myelin and shows essentially no myelin, no oligodendrocytes, no lymphocytes and macrophages, and astrocytes without reactive cytoplasm. ---- The appearance of this hybrid lesion may represent a plaque created by superimposition of a new wave of demyelination on a previously existing inactive plaque (LFB-PAS)
