Tags: , , ,
Emily I Green, Etienne Jaouen, Dennis Klug, Roenick Proveti Olmo, Amandine Gautier, Stéphanie Blandin, Eric Marois,  eLife,  12. 2023.
Lipophorin is an essential, highly expressed lipid transport protein that is secreted and circulates in insect hemolymph. We hijacked the Anopheles coluzzii Lipophorin gene to make it co-express a single-chain version of antibody 2A10, which binds sporozoites of the malaria ...

Homing-based gene drives can introgress rapidly into local genetic backgrounds with minimal chromosomal conversion in Anopheles gambiae

Tags: ,
Tony Nolan, Poppy Pescod, Giulia Bevivino et al.,  Research Square,  2023.
CRISPR-Cas9 gene drive control strategies use a homing selfish genetic element which induces a double-stranded break at the target site and is copied into the opposing chromosome, breaking an essential gene and ensuring super-Mendelian inheritance. During the copying process SNPs ...
