The Incompetence of Mosquitoes—Can Zika Virus Be Adapted to Infect Culex tarsalis Cells?
Gallichotte et al., mSphere . 2023.
Zika virus (ZIKV) is transmitted between humans by Aedes aegypti mosquitoes. However, the 2015 to 2017 outbreak raised questions regarding the role of Culex species mosquitoes in transmission. Investigators attempted to adapt ZIKV to C. tarsalis by serially passaging the virus on cocultured A. aegypti and C. tarsalis cells to identify viral determinants of species specificity. Next-generation sequencing of cocultured virus passages revealed variants of interest that were engineered into nine recombinant viruses. None of these viruses showed increased infection of Culex cells or mosquitoes. Thus, although ZIKV might infect Culex mosquitoes occasionally, Aedes mosquitoes likely drive transmission and human risk. Supported by ORIP (T32OD010437) and NIAID.
Promoting Validation and Cross-Phylogenetic Integration in Model Organism Research
Cheng et al., Disease Models & Mechanisms. 2022.

Model organisms are essential for biomedical research and therapeutic development, but translation of such research to the clinic is low. The authors summarized discussions from an NIH virtual workshop series, titled “Validation of Animal Models and Tools for Biomedical Research,” held from 2020 to 2021. They described challenges and opportunities for developing and integrating tools and resources and provided suggestions for improving the rigor, validation, reproducibility, and translatability of model organism research.
