N
• despite neuron loss, no neurofibrillary tangles or plaques are observed
• mice exhibit spongiform degradation in astrocytes ranging from swelling of astrocytic foot processes to vacuolar changes in the entire cell
• moderate
• mice exhibit a loss of white matter axons in the cerebellum
• mice exhibit a loss of granular neurons in the cerebellum
• the molecular layer in the cerebellum is atrophic
• mice exhibit neuron loss accompanied by disorganization of remaining neurons with degenerative changes in their axon lengths
• normal axoplasm is replaced with axonal swelling with focal accumulation of organelles and often progresses to collapse of the axon
• dendritic processes in the CA1 region of the hippocampus exhibit collapse, vacuolization and reduction in complexity
• Purkinje dendritic processes are tortuous, dilated and exhibit reduced branching
• dendritic processes are tortuous, dilated and exhibit reduced branching
• neuronal damage
• mice exhibit spongiform lesions particularly in the cerebellum where loss of white matter axons, Purkinje cells and granular neurons is observed
• mice exhibit spongiform degradation in astrocytes ranging from swelling of astrocytic foot processes to vacuolar changes in the entire cell
