UCSD study maps a molecular switch to prevent Alzheimer’s in mice

UC San Diego researchers have identified Chromogranin A as a potential molecular switch that could prevent Alzheimer’s-like memory loss; in mice, removing CgA protected against dementia, and peptides that interact with CgA may either provoke or prevent cognitive decline. An AI framework helped confirm consistent patterns across datasets and pinpoint peptides that could halt disease progression, suggesting a preventive, not curative, approach. While results are promising and described as safe in mice, human testing and further funding are needed.
