Gene-edited beagles may offer a future option for people with dog allergies
Summary
Scientists used a gene-editing method called CRISPR to create beagles that do not produce a protein causing allergies in people. These hypoallergenic dogs could help people with dog allergies, but more research is needed to ensure safety and availability.Key Facts
- The gene editing switched off the main gene that makes the allergy-causing protein in dogs.
- Gene-edited beagles named Bailey and Alfie were born healthy in September 2024.
- The allergy-causing protein was not found in the saliva and fur of these dogs.
- Allergy tests showed that the dogs caused fewer allergic reactions in people.
- This is the first time gene editing has been successful in dogs for this purpose.
- The technique used is called CRISPR, which won a Nobel Prize.
- Researchers still need to study the long-term health effects of gene editing in dogs.
- Some experts worry this could reduce adoption of shelter dogs, which are not gene-edited.
