Exceptional Longevity Modifying Allele APOE2 Promotes DNA Signaling Pathways Resisting Cellular Senescence in Human Neurons
Lab studies reveal how a protective gene variant linked to long life strengthens cellular repair mechanisms, suggesting new targets for treating age-related brain disease.
Using human iPSC-derived neuron models, this Buck Institute study demonstrates that the longevity-associated APOE2 allele promotes DNA repair pathways and resistance to cellular senescence in both inhibitory and excitatory neurons, providing mechanistic insight into APOE2's protection against Alzheimer's disease and its association with exceptional longevity. These are preclinical findings requiring human validation but identify DNA repair signaling as a therapeutic target for aging-related neurodegeneration.
