Researchers at the University of Pittsburgh have found that a virus, Merkel cell polyomavirus (MCV), is the cause of Merkel cell carcinoma, an aggressive form of skin cancer. The virus infects normal cells before they turn into cancer cells, and its replication can lead to the death of cancer cells.
