  • Title: Inhibition of dengue virus infection by small interfering RNAs that target highly conserved sequences in the NS4B or NS5 coding regions.
    Author: Villegas PM, Ortega E, Villa-Tanaca L, Barrón BL, Torres-Flores J.
    Journal: Arch Virol; 2018 May; 163(5):1331-1335. PubMed ID: 29392497.
    Abstract:
    Dengue fever is one of the most common viral infections in the world. Although a vaccine against dengue virus (DENV) has been approved in several countries, this disease is still considered a public health priority worldwide. The ability of three small interfering RNAs (FG-siRNAs) targeting conserved sequences in the NS4B and NS5 regions of the DENV genome to inhibit DENV replication was tested in vitro in both Vero and C6/36 cells. The FG-siRNAs were effective against DENV-1, -3, and -4, but not DENV-2. A fourth siRNA specifically targeting the NS5 region of the DENV-2 genome (SG-siRNA) was designed and tested against two different DENV-2 strains, showing high levels of inhibition in both mammalian and insect cells.
