Figure 3From: Immunoreactivity of valosin-containing protein in sporadic amyotrophic lateral sclerosis and in a case of its novel mutant Photographs and photomicrographs of general pathology and neuropathology of the ALS patient with the VCP mutation. (a,b) In this muscle specimen from the right quadriceps muscle, large-group atrophy indicating neurogenic changes is demonstrated, whereas no evidence of IBM is observed (a). The muscle nuclei are normally immunopositive with the anti-TDP-43 antibody (b, arrows), but abnormal inclusions are not detected. (c) H&E staining of a vertebra demonstrates irregular broad trabeculae with disorganized cement lines appearing in a mosaic pattern. (d,e) Macroscopically, the brain shows no apparent atrophy. (f) A KB-stained lumbar spinal cord reveals degeneration of the corticospinal tract (f, arrow). (g) A section of cervical cord stained by H&E shows neuronal loss with gliosis in the anterior horn. (h) Typical Bunina bodies (arrow) are evident in the cytoplasm of this cervical AHC. Scale bars = 250 μm (a), 200 μm (b), 50 μm (c), 1 mm (f), 100 μm (g), and 12.5 μm (h).Back to article page
