With the help of directed evolution, scientists inch closer to developing viral vectors that can cross the human blood-brain barrier to deliver gene therapy.
Genetic variants in Alzheimer’s- and smoking-related genes appear to be under selection pressure, according to a study comparing the genomes of old and young participants.
Research traces the evolution of a gene variant that reduces the risk of Alzheimer’s disease, finding that it originally evolved in response to infectious bacteria.
