Boosting a single brain protein restores memory in mice with Alzheimer's-like disease

Gladstone Institutes researchers discovered that boosting parvalbumin (PV) interneurons restored gamma oscillations—the brain rhythms needed for memory and focus—in mice engineered with Alzheimer's-like disease. The study, published in Neuron, found that in healthy mice these brain cells fire in a precise, sequential pattern; in Alzheimer's mice that pattern broke down, but could be reset by enhancing the protein.

Research was conducted in mice and tested in laboratory conditions; more work is needed to translate these findings into human treatments.
