A groundbreaking study led by researchers at the University of Arizona College of Medicine in Tucson has developed an innovative method for studying Parkinson’s disease in the laboratory.
In doing so, scientists have uncovered important clues that could pave the way for earlier Parkinson’s detection and more effective treatments.
Parkinson’s Disease: A Growing Challenge
Parkinson’s disease is a progressive neurological disorder that affects approximately one million Americans. It manifests itself as difficulty with movement, balance, and cognition, which gradually worsens until everyday tasks such as walking, speaking, and swallowing become daunting.
While there is no cure for Parkinson’s, existing treatments help relieve symptoms, but their effectiveness decreases over time and often causes unwanted side effects.
Diagnosing Parkinson’s Disease: A Late-Stage Challenge
Dr. Lalitha Madhavan, associate professor of neurology at the University of Arizona College of Medicine in Tucson, highlights the difficulty of diagnosing late-stage Parkinson’s disease.
Typically, Parkinson’s is detected when 60-70% of the dopamine neurons in the brain are already impaired or dead.
Although there are treatment options, diagnosing the disease at this advanced stage is like trying to put out a blazing fire with a small glass of water. The need to diagnose Parkinson’s in its early stages is critical.
Creating a human-derived laboratory model
To meet this challenge, Dr. Madhavan’s team developed a human-derived laboratory model to study Parkinson’s disease.
They used cells from Parkinson’s patients and used induced pluripotent stem cell technology to convert adult skin cells called fibroblasts into brain cells.
This innovative approach allowed researchers to study Parkinson’s disease at the cellular level, which could potentially lead to improved diagnoses and treatments.
Skin cells as a window into the brain
Interestingly, the experiments provided another valuable insight: skin cells could serve as a window into the brain. While skin cells themselves do not exhibit neurological symptoms, they share certain molecular “signatures” with brain cells.
These common changes suggest that skin cells could potentially be used to diagnose Parkinson’s disease at an early stage.
Early detection and precision medicine
The team envisions a future in which doctors can detect Parkinson’s disease in its early stages by examining skin cells for specific molecular markers associated with the disease.
This innovative approach could revolutionize early diagnosis and pave the way for tailored treatments based on the genetic profiles of individual patients.
A patented method for early diagnosis
The team of Dr. Madhavan has patented a method for analyzing skin cells to identify molecular signs associated with Parkinson’s disease. Her ongoing research aims to better understand how skin cells change over time to shed light on disease progression and facilitate early detection.
Potential for precision medicine
By leveraging easy access to a patient’s skin cells, this approach could usher in a new era of precision medicine. Doctors may be able to prescribe existing treatments to slow disease progression based on early diagnosis.
At the same time, scientists can develop next-generation Parkinson’s drugs that target the disease in its early stages.
Dr. Madhavan envisions a refined approach to Parkinson’s disease in which different patients receive personalized treatments based on their unique classification within the Parkinson’s spectrum.
This innovative system could increase the effectiveness of treatment and ultimately improve the lives of patients and their healthcare providers.
