A, BParaffin sections of healthy human brain (n = 3), low‐grade glioma (n = 12), anaplastic astrocytoma (n = 7), and glioblastoma (n = 9) were stained for IBA1 (macrophages/microglia), CD15 (granulocytes), and CD3 (T cells) (A). Quantification of leukocyte subsets in human glioma specimens (B). For statistical analysis, Kruskal–Wallis (Dunn's post‐test) test was applied. *P < 0.05, **P < 0.01, ***P < 0.005; data are mean ± SEM. Scale bar: 50 μm.
