Abstract
DNA microarrays were used to assess the innate gene signature in human myeloid dendritic cells infected with chimeric dengue 1–4 vaccines, a wild-type dengue 3 virus, or a classically attenuated serotype 3 vaccine shown to be reactogenic in humans. We observed a very reproducible signature for each of the 4 chimeric dengue vaccines, involving stimulation of type I interferon and associated genes, together with genes encoding chemokines and other mediators involved in the initiation of adaptive responses. In contrast, wild-typeDEN3 virus induced a predominantly inflammatory profile, while the reactogenic attenuated serotype 3 vaccine appeared to induce a blunted response.Keywords
