These parasites are transmitted to vertebrate hosts when mosquitoes of the\n                  <jats:italic>Anopheles<\/jats:italic>\n                  genus probe for a blood meal. Sporozoites, the infectious stage of\n                  <jats:italic>Plasmodium<\/jats:italic>\n                  , transit to the liver within hours of injection into the dermis. Vaccine efforts are hindered by the complexity of the parasite\u2019s lifecycle and the speed at which the infection is established in the liver. In an effort to enhance immunity against\n                  <jats:italic>Plasmodium<\/jats:italic>\n                  , we produced a virus-like particle (VLP)-based vaccine displaying an epitope of TRIO, an\n                  <jats:italic>Anopheles<\/jats:italic>\n                  salivary protein which has been shown to enhance mobility and dispersal of sporozoites in the dermis. Previous work demonstrated that passive immunization with TRIO offered protection from liver infection and acted synergistically with a\n                  <jats:italic>Plasmodium<\/jats:italic>\n                  targeted vaccine. Immunization of mice with TRIO VLPs resulted in high-titer and long-lasting antibody responses that did not significantly drop for over 18 months post-immunization. TRIO VLPs were similarly immunogenic when combined with an anti-malaria vaccine targeting the L9 epitope of the\n                  <jats:italic>Plasmodium falciparum<\/jats:italic>\n                  circumsporozoite protein.However, when used in a malaria challenge mouse model, TRIO VLPs only provided modest protection from infection and did not boost the protection provided by L9 VLPs.\n                <\/jats:p>","DOI":"10.1101\/2024.09.05.611467","type":"posted-content","created":{"date-parts":[[2024,9,8]],"date-time":"2024-09-08T02:50:16Z","timestamp":1725763816000},"source":"Crossref","is-referenced-by-count":1,"title":["Virus-like particle-based vaccines targeting the\n                  <i>Anopheles<\/i>\n                  mosquito salivary protein, TRIO"],"prefix":"10.64898","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4258-2283","authenticated-orcid":false,"given":"Alexandra","family":"Francian","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7230-3834","authenticated-orcid":false,"given":"Yevel","family":"Flores-Garcia","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John R.","family":"Powell","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1580-5245","authenticated-orcid":false,"given":"Nikolai","family":"Petrovsky","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1414-6196","authenticated-orcid":false,"given":"Fidel","family":"Zavala","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5712-4739","authenticated-orcid":false,"given":"Bryce","family":"Chackerian","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"54368","reference":[{"key":"2024091004051046000_2024.09.05.611467v1.1","unstructured":"World malaria report 2023.
