The threat of programmed DNA damage to neuronal genome integrity and plasticity

KW Caldecott, ME Ward, A Nussenzweig - Nature Genetics, 2022 - nature.com
The neuronal genome is particularly sensitive to loss or attenuation of DNA repair, and many
neurological diseases ensue when DNA repair is impaired. It is well-established that the …
