In a world first, a research team at the University of Zurich has successfully treated mice carrying an inherited form of epilepsy. The scientists used gene editing to fix faulty DNA directly in the brain cells of mice, which reduced fever-induced seizures and markedly improved survival rates in an animal model. This approach paves the way for future treatment of inherited epilepsy rather than just managing its symptoms. The work is published in the journal Science Translational Medicine.
