How rogue jumping genes can spur Alzheimer’s, ALS: Our genomes are peppered with DNA segments called retrotransposons that can move from place to place. When unleashed, some can kill nerves and promote inflammation — a discovery that may inspire treatments for neurodegeneration.
Retrotransponsons tied to ALS, Alzheimer’s: Researchers are finding that retrotransposons, which make up over 40% of our genome and are usually inactive, can become reactivated with age or due to malfunctioning proteins like TDP-43 and tau, potentially triggering inflammation and nerve cell damage linked to neurodegenerative diseases such as ALS and Alzheimer’s disease. Researchers are now testing HIV-style antiretroviral drugs to target the viral-like behavior of retrotransposons, with early results showing promise in slowing symptom progression.
