Researchers in Spain and Switzerland report that an experimental molecule called OLE helped restore protective behavior in the brain’s immune cells in animal models of Alzheimer’s disease, reducing amyloid-related pathology and improving performance on memory and movement tests.
Researchers at Mayo Clinic have developed an aptamer-based technique to tag senescent, or so‑called “zombie,” cells in living mouse tissues, work they say could eventually support targeted therapies for age‑related diseases. The project grew out of a chance conversation between two graduate students, according to Mayo Clinic.

Researchers in Germany have identified a rare mutation in the GPX4 enzyme that disables its protective role in neurons, allowing toxic lipid peroxides to damage cell membranes and trigger ferroptotic cell death. Studies in patient-derived cells and mice show a pattern of neurodegeneration that resembles changes seen in Alzheimer’s disease and other dementias.
Researchers at Johns Hopkins Medicine have discovered microscopic nanotube channels in the brain that neurons use to transfer toxic molecules, potentially spreading harmful proteins linked to Alzheimer’s disease. The findings, based on experiments with genetically modified mice, suggest these structures increase early in disease models. The study offers new insights into neurodegenerative disorders and possible therapeutic targets.
