title: Papillomaviruses and potential copathogens.
abstract: An in vitro multistage genital epithelial cell model for cervical cancer that parallels the in vivo neoplastic process has been developed using recombinant human papillomavirus (HPV) DNA and genital cells. HPV-16-immortalized genital cells are responsive to the genotoxic action of known chemical carcinogens (polycyclic hydrocarbons, alkylating agents or cigarette smoke condensate), but are not converted to malignancy. Ras oncogene and human herpes virus-2 did convert HPV immortalized cells to malignancy, whereas human herpes virus-6 infection only increased HPV expression. Human immunodeficiency virus did not infect genital cells.
