Scientists have looked for immune system factors that might help mosquitoes ward off pathogens such as malarial parasites and indirectly protect humans from infection. Yale researchers found one by editing a single gene, which turns out to be crucial for female reproduction.
Researchers in the lab of Erol Fikrig, the Waldemar Von Zedtwitz Professor of Medicine (infectious diseases) and professor of epidemiology and of microbial pathogenesis, edited out a gene suspected of suppressing the mosquito immune system in females of the species Anopheles. They found that the reproductive systems of the mutant mosquitoes were severely disrupted and that the level of parasites that cause malaria was dramatically reduced, researchers report Oct. 28 in the Journal of Experimental Medicine.
