Figure 4From: Neonatal influenza infection causes pathological changes in the mouse brainGlial activation of the influenza-infected brain. Immunohistochemical staining of microglia (A, C) and astrocytes (B, D) in the hippocampus of infected mice at 5 dpi with age-matched control mice. Note that many glial cells with activated morphology are seen in the infected mice brain (A, B), whereas resting glial cells are stained in control mouse brain (C, D). Scale bar = 50 μm.Back to article page
