Herpesviruses and Alzheimer€™s Disease

Risk factors for the chronic neurodegenerative condition known as Alzheimer€™s disease (AD) include many cellular genes and pathogenic microbes. Nucleic acids of two ubiquitous human herpesviruses, HHV-6A and HHV-7, have been found at higher levels in AD brains compared with healthy controls, and appear to regulate genes implicated in risk of developing the disease.
