Significantly higher expression of CD86 was observed in Grade-III astrocytoma as compared with oligoastrocytoma and oligodendroglioma of the same grade, while oligodendroglioma presented lower CD86 expression as opposed to oligoastrocytoma (P<1.4*10-14) (Figure 5A). The gene discussed is CD86; the disease is astrocytoma (excluding glioblastoma).
