The Journal of Neuroscience recently published a new study with promising news on the battle against Alzheimer’s disease. The study, conducted on rats, found that turning off a certain genetic pathway halted the production of a protein that “signals” the body to pursue the cell disturbances that make up Alzheimer’s disease. Importantly, interrupting those signals allowed the body to repair the affected brain cells. This is the first time that any study has seen a reversal of conditions, and this finding will undoubtedly lead to more studies to explore this potentially exciting development.
