The heatmap shows that vehicle treatment group had significantly increased expression of CD11b (microglia and MoDMs), B220 (B cells), CD4 (CD4+ T cells), CD8a (CD8+ T cells), CD44 (CD4 Tem and CD8 Tem cells), CD25 (Tregs), CD11c (cDCs), and CD49b (NK cells), indicating an elevated immune response and inflammation following ischemic stroke. This evidence concerns the gene CD44 and ischemic stroke.
