There are currently no approved human vaccines and a lack of prophylactic and therapeutic treatments. Understanding host responses to infection may reveal potential intervention targets to reduce virus replication and disease progression. The use of\n                  <jats:italic>Drosophila melanogaster<\/jats:italic>\n                  as a model organism to understand innate immunity and host antiviral responses is well established. Previous studies revealed that insulin-mediated signaling regulates WNV infection in invertebrates by regulating canonical antiviral pathways. Because insulin signaling is well-conserved across insect and mammalian species, we sought to determine if results using\n                  <jats:italic>D. melanogaster<\/jats:italic>\n                  can be extrapolated for the analysis of orthologous pathways in humans. Here, we identify insulin-mediated endothelin signaling using the\n                  <jats:italic>D. melanogaster<\/jats:italic>\n                  model and evaluate an orthologous pathway in human cells during WNV infection. We demonstrate that endothelin signaling reduces WNV replication through the activation of canonical antiviral signaling. Taken together, our findings show that endothelin-mediated antiviral immunity is broadly conserved across species and reduces replication of viruses that can cause severe human disease.\n                <\/jats:p>\n                <jats:sec>\n                  <jats:title>IMPORTANCE<\/jats:title>\n                  <jats:p>\n                    Arboviruses, particularly those transmitted by mosquitoes, pose a significant threat to humans and are an increasing concern because of climate change, human activity, and expanding vector-competent populations. West Nile virus is of significant concern as the most frequent mosquito-borne disease transmitted annually within the continental United States. Here, we identify a previously uncharacterized signaling pathway that impacts West Nile virus infection, namely endothelin signaling. Additionally, we demonstrate that we can successfully translate results obtained from\n                    <jats:italic>D. melanogaster<\/jats:italic>\n                    into the more relevant human system. Our results add to the growing field of insulin-mediated antiviral immunity and identifies potential biomarkers or intervention targets to better address West Nile virus infection and severe disease.\n                  <\/jats:p>\n                <\/jats:sec>","DOI":"10.1101\/2023.01.17.524426","type":"posted-content","created":{"date-parts":[[2023,1,18]],"date-time":"2023-01-18T22:45:10Z","timestamp":1674081910000},"source":"Crossref","is-referenced-by-count":0,"title":["Insulin-mediated endothelin signaling is antiviral during West Nile virus infection"],"prefix":"10.64898","author":[{"given":"Chasity E.","family":"Trammell","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Evelyn H.","family":"Rowe","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brianne J.","family":"Jones","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aditya B.","family":"Char","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephen","family":"Fawcett","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura R.H.","family":"Ahlers","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6394-332X","authenticated-orcid":false,"given":"Alan G.","family":"Goodman","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"54368","reference":[{"key":"2023012009150757000_2023.01.17.524426v1.1","doi-asserted-by":"crossref","first-page":"96","DOI":"10.3389\/fcimb.2018.00096","article-title":"The Immune Responses of the Animal Hosts of West Nile Virus: A Comparison of Insects, Birds, and Mammals","volume":"8","year":"2018","journal-title":"Front Cell Infect Microbiol"},{"key":"2023012009150757000_2023.01.17.524426v1.2","unstructured":"Centers for Disease Control and Prevention (CDC). 1999.
