RESUMO
The report describes the establishment and characterization of a mouse xenograft transplantation model for the study of papillomavirus infection of bovine skin. Calf scrotal skin was inoculated with bovine papillomavirus type 2 before grafting it to the dorsum of severe combined immunodeficient mice. The grafted skin contained epidermis, dermis, and a thin layer of fat. After 5 months the induced warts not only showed histological features of papillomavirus infections but also tested positive for viral DNA and papillomavirus capsid antigen. The formation of infectious virions was demonstrated by inoculation of new transplants with crude extract from the induced warts as well as in a cell culture focus assay. Topical application of bromovinyl-2′-deoxyuridine led to a reduction in viral DNA content in the developing wart. This small-animal xenograft model should be useful for characterizing antiviral compounds and providing an understanding of the regulation of papillomavirus infections.
