No. 10 – Virus long thought harmless may trigger Parkinson’s
The causes of Parkinson’s disease aren’t fully understood — some patients have underlying genetic mutations, but other factors, such as environmental exposures, also may play a role in triggering the disease. In a study published this summer, researchers found that brain samples from people with Parkinson’s were more likely than those from individuals without the disease to be infected with human pegivirus (HPgV), a common infection that had long been thought to be harmless. Findings suggest that HPgV infection may play a role in the development of Parkinson’s, and researchers have also found that immune responses to the virus may vary in people with or without certain Parkinson’s-causing mutations.
