Since it was demonstrated that microglia phenotype changes from anti- to pro-inflammatory with the progression of cerebral ischemia (Fumagalli et al., 2015; Ma et al., 2017) we isolated CD11b+ cells from the ipsi- and contra-lateral brain hemispheres of mice at 72 h after ischemia and analyzed by RT-qPCR the same set of genes. This evidence concerns the gene ITGAM and brain ischemia.
