Project description:Aedes aegypti (L.) is the primary vector of many emerging arboviruses. Insecticide resistance among mosquito populations is a consequence of the application of insecticides for mosquito control. We used RNA-sequencing to compare transcriptomes between permethrin resistant and susceptible strains of Florida Ae. aegypti in response to Zika virus infection. A total of 2,459 transcripts were expressed at significantly different levels between resistant and susceptible Ae. aegypti. Gene ontology analysis placed these genes into 7 categories of biological processes. The 863 transcripts were expressed at significantly different levels between two strains (up/down regulated) more than 2-fold. Quantitative real-time PCR analysis validated Zika-infected response, and suggested a highly overexpressed P450, with AAEL014617 and AAEL006798 as potential candidates for the molecular mechanism of permethrin resistance in Ae. aegypti. Our findings indicated that most detoxification enzymes and immune system enzymes altered their gene expression between the two strains of Ae. aegypti in response to Zika virus infection. Understanding the interactions of arboviruses with resistant mosquito vectors at the molecular level allows for the possible development of new approaches in mitigating arbovirus transmission. This information sheds light on Zika-induced changes in the insecticide resistance of Ae. aegypti with implications for mosquito control strategies.

Project description:Aedes aegypti mosquitoes infect hundreds of millions of people each year with dangerous viral pathogens including dengue, yellow fever, Zika, and chikungunya. Progress in understanding the biology of this insect, and developing tools to fight it, depends on the availablity of a high-quality genome assembly. Here we use DNA proximity ligaton (Hi-C) and Pacific Biosciences long reads to create AaegL5 - a highly contiguous A. aegypti reference.

Project description:Zika virus (ZIKV) of the Flaviviridae family is a recently emerged mosquito-borne virus that has been implicated in the surge of the number of microcephaly instances in south America. The virus is transmitted mainly by the mosquito Aedes aegypti that also vectors dengue virus. Considering rather recent rapid spread of the virus and its declaration as a global health emergency by the World Health Organization, little is known about the interactions of the virus with the mosquito vector. In this study, we investigated the transcriptome profiles of whole Ae. aegypti mosquitoes in response to ZIKV infection at 2, 7 and 14 days post-infection using deep sequencing. Results showed a large number of transcripts were altered at each time point following infection, but 18 transcripts were commonly changed at the three time points. The outcomes provide a basic understanding of Ae. aegypti responses to ZIKV and help determining host factors involved in replication or anti-viral response against the virus.

Project description:Aedes aegypti SP strain vs. SMK strain. Aedes aegypti is the major vector of yellow fever and dengue/dengue hemorrhagic fever. Starting with a population collected from Singapore, we established a pyrethroid-resistant A. aegypti strain (SP) and investigated three major possible mechanisms of insecticide resistance. After 10 generations of adult selection, an A. aegypti strain developed 1650-fold resistance to permethrin, which is one of the most widely used pyrethroid insecticides for mosquito control. SP larvae also developed 8790-fold resistance following selection of the adults. Prior to the selections, the frequencies of V1016G and F1534C mutations in domains II and III, respectively, of voltage-sensitive sodium channel genes (Vssc) were 0.44 and 0.56, respectively. In contrast, only G1016 alleles were present after two permethrin selections, indicating that G1016 can contribute more to the insensitivity of Vssc than C1534. In vivo metabolism studies showed that the SP strain excreted permethrin metabolites more rapidly than the susceptible SMK strain. Pretreatment with piperonyl butoxide caused strong inhibition of excretion of permethrin metabolites, suggesting that cytochrome P450 monooxygenases (P450s) play an important role in resistance development. In vitro metabolism studies also indicated an association of P450s with resistance. Microarray analysis showed that multiple P450 genes were over-expressed during the larval and adult stages in the SP strain. Following quantitative real time PCR, we focused on two P450 isoforms, CYP9M6 and CYP6BB2, and confirmed that they were capable of detoxifying permethrin to 4'-HO-permethrin. Over-expression of CYP9M6 was partially due to gene amplification. Association analysis demonstrated that CYP9M6 and CYP6BB2 complementarily conferred permethrin resistance. Two other P450s (CYP9J26 and CYP9J28), which are capable of metabolizing permethrin, were also over-expressed in the SP strain, indicating that at least four P450 isoforms are likely involved in resistance development. Our data show that it is unlikely that reduced cuticle penetration of permethrin contributes to resistance.

Project description:Arthropod-borne viruses (arboviruses) such as dengue virus (DENV) and Zika virus (ZIKV) pose a significant threat to global health. Novel approaches to control arbovirus spread are focused on harnessing the antiviral immune system of their main vector, the Aedes aegypti mosquito. In arthropods, genes of the Vago family are often presented as analogs of mammalian cytokines with potential antiviral functions, but the role of Vago genes upon virus infection in Ae. aegypti is largely unknown. We performed a phylogenetic analysis of the Vago gene family in Diptera that prompted us to focus on a Vago-like gene that we named VLG-1. Using CRISPR/Cas9-mediated gene editing, we generated a VLG-1 mutant line of Ae. aegypti that revealed a proviral effect of this gene upon DENV and ZIKV infection. In the absence of VLG-1, virus dissemination throughout the mosquito’s body was impaired, albeit not altering virus transmission rates. A tissue-specific transcriptome analysis revealed that the loss of VLG-1 impacted numerous biological processes potentially linked to viral replication, such as the oxidative stress response. Our results challenge the conventional understanding of Vago-like genes as antiviral factors and underscores the need for further research to elucidate the molecular mechanisms underlying mosquito-arbovirus interactions.
