mortality/aging
• following LMCV infection, mice exhibit an increased survival
• mice become moribund at 8 to 12 months of age

nervous system
• rare at 8 to 12 months of age
• mice exhibit a dilation of blood vessels and endothelial cell hypertrophy in the brain
• mice exhibit a predominantly lymphocyte infiltration in the brain
• meningoencephalitis
• ependymal cells lining the ventricles exhibit swelling and irregular configurations of their cell surface
• epithelial cells of the choroids plexus exhibit swelling and irregular configurations of their cell surface
• at 10 to 12 months of age, mice exhibit calcification in the basal ganglia
• at 10 to 12 months of age, mice exhibit calcification in the cerebellum
• calcifications in the granule layer consists of concentric and often laminated deposits
