Increasing drug resistance has intensified the need for novel therapeutics, including treatments with intrinsic transmission-blocking properties. In this study, we demonstrate that the isoprenoid abscisic acid (ABA) modulates signaling in the mammalian host to reduce parasitemia and the formation of transmissible gametocytes and in the mosquito host to reduce parasite infection. Oral ABA supplementation in a mouse model of malaria was well tolerated and led to reduced pathology and enhanced gene expression in the liver and spleen consistent with infection recovery. Oral ABA supplementation also increased mouse plasma ABA to levels that can signal in the mosquito midgut upon blood ingestion. Accordingly, we showed that supplementation of a <jats:italic>Plasmodium falciparum<\/jats:italic>-infected blood meal with ABA increased expression of mosquito nitric oxide synthase and reduced infection prevalence in a nitric oxide-dependent manner. Identification of the mechanisms whereby ABA reduces parasite growth in mammals and mosquitoes could shed light on the balance of immunity and metabolism across eukaryotes and provide a strong foundation for clinical translation.<\/jats:p>","DOI":"10.4269\/ajtmh.15-0904","type":"journal-article","created":{"date-parts":[[2016,3,22]],"date-time":"2016-03-22T03:56:18Z","timestamp":1458618978000},"page":"1266-1275","source":"Crossref","is-referenced-by-count":28,"title":["Supplementation with Abscisic Acid Reduces Malaria Disease Severity and Parasite Transmission"],"prefix":"10.4269","volume":"94","author":[{"given":"Elizabeth K.
