Alzheimer’s Researchers Detect Genetic Recombination in the Brain

For the first time, scientists have identified gene recombination, or “mixing and matching” of DNA, in the brain.

New technology revealed DNA in neurons is recombined, producing thousands of previously unknown gene variations—and identifying a potential near-term treatment for Alzheimer’s disease.

The study, published in Nature and authored by Jerold Chun, M.D., Ph.D., professor and senior vice president of Neuroscience Drug Discovery at SBP, focused on the Alzheimer’s-linked gene, APP, and discovered it is recombined by using the same type of enzyme found in HIV. This finding indicates existing FDA-approved antiretroviral therapies for HIV that block reverse transcriptase might also be able to halt the recombination process—and could be explored as a new treatment for Alzheimer’s disease.
