Virus hunting season open
New viruses have been popping up in industrial water-cooling towers, in Antarctica and salty deserts. Erwin van Meir, from Winship Cancer Institute of Emory University, and his collaborators managed to find two inside someone’s metastatic tumor.
Working with Terry Fei Fan Ng and Eric Delwart from UCSF, Van Meir identified two new species of anellovirus, a family of viruses first discovered in the 1990s. The new viruses come from a patient with a melanoma that had metastasized to the brain and was operated on at Emory University Hospital.
The results were recently published in Oncotarget.
“We have no evidence that these two viruses were involved in the tumor’s formation, but the data are proof of principle that the metagenomics method used can discover more unknown viruses in human brain tumors,” Van Meir says. Dr. Van Meir is a faculty member in the CB, GMB and NS programs.
