Immunofluorescence staining also showed co-labeling of IL-13Rα1 and microglia/macrophage (Iba1+) in the peri-infarct cortex and striatum 3 days after tMCAO (Fig. 3C), indicating the express of IL-13Rα1 on morphologically activated microglia/macrophage after stroke. This evidence concerns the gene AIF1 and Stroke.
