Researchers master gene editing technique in mosquito that transmits deadly diseases

Researchers master gene editing technique in mosquito that transmits deadly diseasesRockefeller University researchers have successfully harnessed a technique, CRISPR-Cas9 editing, to use in an important and understudied species: the mosquito, Aedes aegypti, which infects hundreds of millions of people annually with the deadly diseases chikungunya, yellow fever, and dengue fever.

Research shows combination of sensory signals draw mosquitoes in for a bite

Researchers used a genome editing technique to engineer a mutant version of the Aedes aegypti mosquito, which spreads yellow fever. The mutant was unable to detect carbon dioxide, and studies showed that this hindered its ability to detect a host, even in the presence of other sensory cues like heat and odor. The results can help inform the design of chemical repellents to block host-seeking behavior in both Aedes aegypti and Anopheles gambiae, which spreads malaria. More »
