The human T-lymphotropic virus type 1, a cancer-causing retrovirus, exploits key proteins in host cells to extend the life of those cells, thereby prolonging its own survival and ability to spread, according to a new study. The virus, which causes adult T-cell leukemia and lymphoma, produces a protein called p30 that targets two important cell proteins, one involved in DNA damage repair, the other involved in the destruction of proteins within the cell.
