Tumors of the nervous system are virtually negative for HCMV antigens. (A) Neuroblastoma stained with the DAKO-antibody against HCMV early antiegen (EA) and HCMV immediate-early antigen (IEA) showing only HCMV-negative nuclei. (B) Human medulloblastoma stained with the DAKO antibody against HCMV EA/IEA also being completely negative. (C and D) Two different glioblastoma specimens also being negative for HCMV EA/IEA. (E) Glioblastoma being slightly positive for HCMV in some areas. (F) Specimen of a patient suffering from cerebellar HCMV encephalitis showing HCMV EA/IEA-positive nuclei of neurons and surrounding glial cells. (Scale 100 µm).
