Read More Scince News Health a month ago APOE4-driven Nell2 may signal Alzheimer’s decades earlier Gladstone researchers link APOE4 to excess Nell2, which shrinks neurons and triggers hippocampal hyperactivity decades before memory loss. Lowering Nell2 reversed these changes in mice, pointing to a potential intervention target.
