Thioester-Containing Protein 1 (TEP1) Transgenic Mosquito Enhances Dengue Virus (DENV) Infection. (A) Aedes aegypti control and loss-of-function transgenic (AaCPA>2miR-TEP1) mosquitoes were fed an infectious DENV blood meal. The whole bodies of infected mosquitoes were collected 0, 2, 4, 6, 8, 10, and 12 days after the infectious blood meal and viral titers were determined and quantified with a plaque assay. (B) Ae. aegypti mosquitoes with silenced TEP1 or mosquitoes from the loss-of-function transgenic line were fed an infectious DENV blood meal. Midguts from infected mosquitoes were collected seven days after the infectious blood meal and the viral titers were determined by plaque assay. Letters indicate the statistical significance according to Tukey’s multiple comparison test. There is no significant difference between them (p > 0.05). Control: Aedes aegypti UGAL/Rockefeller strain without any transgenic materials or dsRNA treatment.
