Gene editing can make chickens resistant to bird flu

Chickens genetically modified to be impervious to bird flu may one day prevent the spread of the disease on farms, a study suggests.

Just small tweaks to a single gene made chickens resistant to an avian influenza infection, researchers report October 10 in Nature Communications.

The gene, known as ANP32A, provides the instructions that tell chicken cells how to make a protein that flu viruses rely on to successfully hijack cells. Disrupting the avian virus’s ability to commandeer the protein stopped most genetically edited birds from getting infected.
