Story summary

A groundbreaking study by Cortexyme reveals a troubling connection between oral infections and Alzheimer's disease. Experiments with mice showed that the bacteria P. gingivalis not only invaded the brain but also spurred the production of amyloid beta. Alarmingly, toxic enzymes called gingipains were discovered in the brains of Alzheimer's patients, hinting at a possible role in the disease's advancement, even among those undiagnosed.
