‘Landmark study’ shows brain cells revamp their DNA, perhaps sparking Alzheimer’s disease

Unlike most cells in our bodies, the neurons in our brain can scramble their genes, scientists have discovered. This genome tampering may expand the brain’s protein repertoire, but it may also promote Alzheimer’s disease, their study suggests.

“It’s potentially one of the biggest discoveries in molecular biology in years,” says Geoffrey Faulkner, a molecular biologist at the University of Queensland in Brisbane, Australia, who wasn’t connected to the research. “It is a landmark study,” agrees clinical neurologist Christos Proukakis of University College London.
