Figure 1

Specimens of human astrocytoma grades I–IV, immunohistochemically stained for FPR1, percentage of positive cells and antigenic load. Micrographs A–D show astrocytic tumours with WHO grades I–IV, respectively. In the low-grade tumours (A and B), diffuse staining can be observed. In the high-grade tumours (C and D), the staining intensity is much less homogeneous. Bars=100 μm. (E) Percentages of positive tumour cells in the various grades of astrocytic tumours (dark line in the box refers to the median, whiskers indicate the 95% CI). The lowest percentage relative to the other three grades is found in glioblastomas (*P<0.05). (F) Antigenic load, the glioblastoma group has the smallest values relative to lower grades (*P<0.05).
