ABSTRACT
The diagnostic hallmarks of amyotrophic lateral sclerosis (ALS) are degeneration of upper and lower motor neurons and of corticospinal tracts. Here, we demonstrate the suitability of the gliosis marker [3H]PK11195 for quantitative evaluation of tract degeneration in ALS in vitro. Binding of [3H]PK11195 was increased in lateral and ventral white matter of ALS spinal cords but not in the anterior horn, in spite of a dramatic loss in muscarinic binding sites and a high level of oxidatively modified protein. Labeling of activated microglia with [11C]PK11195 may also allow tract degeneration in ALS to be visualized in vivo.
