Figure 4

Double immunofluorescence staining for tumor necrosis factor (TNF) α (green) and glial fibrillary acidic protein (GFAP) (red) in the walls of the basilar artery (BA) and in surrounding brain tissue at 0 to 24 h post-subarachnoid hemorrhage (SAH). There was no expression of TNFα in the walls of the BA at 0 to 24 h post-SAH, but an enhanced TNFα immunoreactivity was seen in the brain tissue. This was colocalized with GFAP (white arrows in merged picture). GFAP expression was observed in astrocytes around BA and in the surrounding brain tissue.
