| Summary / Zusammenfassung | Some medical procedures are associated with a parenteral exposure of humans to animal endogenous retroviruses. These include the endogenous avian retrovirus EAV-0 which is present in all chicken-cell–derived vaccines and the porcine endogenous retrovirus (PERV) contained in porcine tissues considered for xenotransplantation. We propose to investigate possible interactions of these two viruses with the human host in vitro and in vivo. The proposed investigations will address the following points: (i) the potential of these agents for infection of human cells (ii) the potential of these agents for expression in human cells (iii) the potential for interaction with co-expressed human retroviruses or members of other virus families; (iv) induction of antibody responses (v) the possibility that endogenous retroviral DNA may, as suggested by a mouse model, be taken up by the gastrointestinal tract, transported to various body tissues and lead to false-positive results in ultrasensitive molecular tests. The proposed studies address important safety questions. Retroviral safety is a central public health issue for all medical procedures that involve animal products. |
