Characterizes astrocyte morphological responses in CA3 hippocampus during viral encephalitis, indicating distinct vulnerabilities.

To investigate whether astrocytes from different hippocampal layers show unique morphological responses to Piry virus-induced encephalitis.
Inoculated adult female Swiss mice with Piry virus intranasally.
Sacrificed mice at 20 or 40 days post-infection for analysis.
Conducted 3D reconstructions of GFAP+ astrocytes from specific layers.
Employed hierarchical clustering, linear discriminant analysis (LDA), and generalized linear models for evaluation.
Identified 3-4 distinct astrocyte morphotypes per layer and time point.
At 20 dpi, SLM astrocytes were significantly more complex than SO astrocytes.
Responses at 40 dpi were more heterogeneous, indicating changing astrocyte reactivity over time.
