Abstract
The neuronal ceroid lipofuscinoses (NCLs, Batten disease) are fatal inherited neurodegenerative diseases characterized by gross brain atrophy, blindness, and intracellular accumulation of lysosome-derived storage bodies. A CLN6 form in sheep is studied as a large animal model of the human diseases. This study describes neuropathological changes in brains from presymptomatic affected sheep. Activated astrocytes and focal clusters of activated microglia were present in outer layers of occipital and somatosensory cortical regions as early as 12 days of age, together with activated perivascular macrophages. Astrocytic activation and progressive transformation of microglia to brain macrophages preceded neurodegeneration and spread to different cortical areas, most prominently in regions associated with clinical symptoms. In contrast, storage body accumulation was much more evenly spread across regions. These data support suggestions that neurodegeneration and storage body accumulation may be independent manifestations of CLN6 mutation and indicate that glial cell activation may be an important mediator in pathogenesis.
