Fig 1. Schematic diagram illustrating interaction between microglia, astrocytes, endothelial cells, and neurons in prion diseases.
PrPSc triggers proinflammatory phenotype in microglia [40]. Reactive microglia activate astrocytes [7]. In reactive state, astrocytes lose homeostatic functions that support neurons [9]. Reactive astrocytes associated with prion disease are neurotoxic [7] and have deleterious effects on endothelial cells of BBB [8].

Fig 2. Principle component analysis (PCA) of region-specific differences in expression of astrocyte specific across 5 animal groups: prion-infected mice, mice subjected to TBI, 5XFAD mouse model of Alzheimer’s disease, mice subjected to ischemic insult (MCAO, middle cerebral artery occlusion), and aged 24-month-old mice.
Cortex, hippocampus, thalamus, and hypothalamus were analyzed in each group. PCA revealed well resolved continuums of astrocytic phenotypes shown on bottom right: one shared by the cortex and hippocampus and another by the thalamus and hypothalamus. Each dot represents an individual animal. The figure was adapted from [21].
