A drug candidate developed by Salk researchers, and previously shown to slow aging in brain cells, successfully reversed memory loss in a mouse model of inherited Alzheimer’s disease. The new research, published online in July 2020 in the journal Redox Biology, also revealed that the drug, CMS121, works by changing how brain cells metabolize fatty molecules known as lipids.
In the new study, Maher and colleagues tested the effect of CMS121 on mice that develop the equivalent of Alzheimer’s disease. Maher’s team gave a subset of the mice daily doses of CMS121 beginning at 9 months old—the equivalent of middle age in people, and after the mice have already begun to show learning and memory problems. The timing of the lab’s treatment is akin to how a patient who visits the doctor for cognitive problems might be treated, the researchers say.
