MYB immunoreactivity (IR) in low-grade gliomas. Two broad categories of MYB IR were demonstrated; (i) strong nuclear IR of nearly all tumor cells as demonstrated by this diffusely infiltrating astrocytoma, in which normal glia and blood vessels are immunonegative (a, b), and weak to moderately strong nuclear IR of scattered tumor cells in this cerebellar pilocytic astrocytoma (c, d), and this anaplastic astrocytoma (e,f).
