New Northwestern Medicine Study Links Virus to Parkinson’s Disease: What Naperville Residents Should Know
Naperville, IL – A recent study from Northwestern Medicine has revealed a possible connection between a common virus and the development of Parkinson’s disease. This discovery could have important implications for Parkinson’s disease research and future treatment options, especially for patients and families in Naperville and throughout Illinois.
Understanding Parkinson’s Disease and Its Causes
Parkinson’s disease is a progressive neurological disorder that affects more than one million people in the United States. While some cases are linked to genetics, the cause of most cases remains unknown. Researchers have long suspected that environmental factors, including viruses, might play a role in triggering or contributing to the disease.
The Northwestern Medicine Research
A team led by Dr. Igor Koralnik, chief of neuroinfectious diseases and global neurology at Northwestern Medicine, set out to explore whether viruses could be linked to Parkinson’s disease. Using a specialized tool called “ViroFind,” which can detect over 500 types of viruses in clinical samples, the researchers examined brain tissue from individuals who had Parkinson’s disease and compared it to those without the condition.
Their findings were significant: in 50% of the Parkinson’s cases, they detected Human Pegivirus (HPgV), a virus not previously associated with any disease, in the brain tissue. This virus was not found in any of the control samples. Additionally, HPgV was present in the spinal fluid of Parkinson’s patients, but not in those without the disease.
Immune System Changes and Genetic Factors
The study also found that Parkinson’s patients with HPgV in their brains showed more severe disease and changes in immune system signaling. Further analysis of blood samples from over 1,000 participants in the Parkinson’s Progression Markers Initiative revealed similar immune-related changes linked to HPgV.
Interestingly, the research highlighted that patients with a specific Parkinson’s-related gene mutation (LRRK2) responded differently to HPgV compared to those without the mutation.
What This Means for Parkinson’s Disease Treatment
Currently, there is no test available to determine if someone is carrying Human Pegivirus. However, this research opens new possibilities for future Parkinson’s disease treatment. Since HPgV is closely related to the Hepatitis C virus, for which effective medications already exist, there is hope that similar treatments could be developed if further studies confirm these findings.
Dr. Koralnik noted, “This is an exciting new direction for Parkinson’s research. If our results are confirmed, it may be possible in the future to repurpose existing medications to target Human Pegivirus in the brain.”
Ongoing Research and Next Steps
The Northwestern Medicine team plans to continue their research to determine how common HPgV is among Parkinson’s patients and whether it plays a direct role in the disease. Their findings were published in the July 8 edition of the journal JCI Insight.
