Dengue virus and dendritic cells

Little is known about the pathogenesis of the Dengue virus, a mosquito-borne flavivirus that causes about 50 million human infections annually, some of which may be fatal. Recent studies have demonstrated two subsets of dendritic cells, monocyte-derived dendritic cells and human skin Langerhans cells, that are targets for Dengue virus infection (pages 816–820).
