Herpesviruses, polyomaviruses, and papillomaviruses have all been detected in glioblastoma cells and/or cell lines. Our group first published evidence of human cytomegalovirus (CMV), a herpesvirus, in glioblastoma specimens from immunocompetent patients in 2002. However, the discovery of CMV and other viruses in glioblastoma has met with controversy following several studies that failed to detect viral particles in GBM. Here we summarize the known relationships between viruses and malignant gliomas, including viral detection in GBM, the oncomodulatory effects of GBM-associated viruses, and the novel ways by which investigators are targeting viruses for the treatment of glioblastoma.
