    Abstract:
    Chronic relapsing experimental allergic encephalomyelitis (EAE) lesions that resemble those seen in multiple sclerosis (MS) were produced in young Hartley and strain 13 guinea pigs (Lassmann and Wisniewski 1979). To study distributions of myelin-associated glycoprotein (MAG), myelin basic protein (MBP), and glial fibrillary acidic protein (GFAP) in these lesions, paraffin and semithin epon sections of CNS from eight of these guinea pigs were immuno-stained with antisera to these proteins according to the peroxidase-antiperoxidase (PAP) method. In lesions with active myelin sheath breakdown, changes in anti-MAG and anti-BP immunoreactivity corresponded closely. Abnormal and/or decreased anti-MAG staining did not extend beyond margins of lesions into surrounding areas containing myelin sheaths stained normally by anti-BP and by histological stains for myelin. GFAP-stained astrocyte processes were more numerous and much larger in more chronic lesions. Anti-MAG and anti-BP both stained regenerating myelin sheaths which were very numerous in both paraffin and epon sections. In the latter, anti-MAG also stained some myelin-forming oligodendroglia. The results are additional evidence suggesting that in chronic relapsing EAE, myelin sheaths are the primary target. Oligodendroglia appear to be relatively unaffected and remyelinate most of the demyelinated axons.
