摘要: Several dengue (DEN) virus vaccines are in development; however, the lack of a reliable small animal model which to test them is major obstacle. Because evidence suggests that interferon (IFN) involved human anti-DEN response, we tested mice deficient their IFN functions as potential models. Intraperitoneally administered mouse-adapted DEN 2 was uniformly lethal AG129 (which alpha/beta and gamma receptor genes), regardless age. Immunized were protected from challenge, survival times increased following passive transfer polyclonal antibody. These results demonstrate promising for vaccine trials.
