Visualization of microglia in midbrain with GSA-I-B4 lectin (A-F) and in motor cortex with OX-42 (G) and OX-6 (H) during symptomatic disease. A, low power view of midbrain reveals enhanced lectin staining in the red nucleus. B, higher magnification shows that enhanced lectin reactivity is confined strictly to red nucleus region (arrows indicate perimeter of red nucleus). C, microglial fusions are interspersed with rubrospinal neurons that appear undamaged. D, lectin-positive microglial fusion (giant cell) within red nucleus. E, oculomotor nucleus reveals normal-appearing motor neurons and lack of microgliosis. F, substantia nigra (pars compacta) shows presence of normal, ramified microglial cells. G, motor cortex shows normal, ramified microglia. H, single, ramified microglial cell positive with OX-6 (arrow) near lateral ventricle. Scale bars: 400 μm (A); 200 μm (E); 100 μm (B,H); 50 μm (C,F,G); 20 μm (D).
