Layer‐Specific Astrocyte Morphological Responses in the CA3 Hippocampus Region During Piry Virus‐Induced Encephalitis

Hippocampus, Volume 36, Issue 2, March 2026.
ABSTRACT Astrocytes from distinct hippocampal layers exhibit region‐specific morphological traits, which may be influenced by their local microenvironment. During viral encephalitis, these cells undergo dynamic changes that can reflect layer‐specific vulnerability. In this study, we characterized whether astrocytes from different CA3 hippocampal layers
