In this issue of Nature Neuroscience, Golden et al. unveil a mouse model that enables in vivo ‘switching’ from the Alzheimer’s risk gene APOE4 to the protective gene APOE2. This genetic conversion reshapes Alzheimer’s disease-related metabolism, reduces neuropathology, and enhances cognition, demonstrating the beneficial effects of APOE genetic targeting as a promising therapeutic strategy.
