Genetic Engineering and Diseases – Gene Drive & Malaria
Kurzgesagt – In a Nutshell・6 minutes read
Genetic engineering has created mosquitoes immune to malaria through CRISPR technology, potentially eradicating the disease by ensuring 99.5% of offspring carry the anti-malaria gene, despite ethical concerns about large-scale genetic modification to combat diseases like malaria.
Insights
- CRISPR technology allows for the creation of malaria-immune mosquitoes by inserting an antibody gene targeting Plasmodium, offering a potential solution to eradicating the disease.
- The ethical debate surrounding genetic engineering to combat diseases like malaria emphasizes the balance between saving lives and the risks and consequences associated with large-scale genetic modifications.

"CRISPR Mosquitoes: Eradicating Malaria with Gene Drive"
- Malaria, caused by Plasmodia parasites transmitted by mosquitoes, is a deadly disease with severe symptoms like high fever, convulsions, and potential death if it breaches the blood-brain barrier.
- The Zika virus, also carried by mosquitoes, causes birth defects and spread rapidly in 2015, highlighting the mosquito's role as a perfect carrier for diseases.
- Genetic engineering using CRISPR technology has enabled the creation of mosquitoes immune to malaria by adding an antibody gene targeting Plasmodium, potentially eradicating the disease.
- The gene drive method ensures that the engineered gene becomes dominant in mosquito populations, with 99.5% of offspring carrying the anti-malaria edit, offering a rapid solution to combat the disease.
- While concerns exist about the ethical implications and potential risks of genetic modification on a large scale, the urgency to save lives from diseases like malaria prompts a debate on the responsible use of this technology.
