A sting of hope for Parkinson’s disease
Peer-Reviewed Publication
This month, we’re spotlighting Parkinson’s disease research in recognition of Parkinson’s Awareness Month. Here, we’ll share the latest research on Parkinson’s disease, how scientists are working to better understand its causes and progression, advances in treatment and care, and more.

The brain continuously produces metabolic waste that must be removed to maintain healthy function. Cerebrospinal fluid (CSF) plays a central role in this process by carrying away proteins such as amyloid-β, phosphorylated tau, and α-synuclein, which are linked to Alzheimer's disease, Parkinson's disease, and other neurodegenerative disorders when they accumulate abnormally.
Scientists have long known that much of this waste ultimately leaves the brain through lymphatic vessels and drains into lymph nodes in the neck. Yet one fundamental question has remained unanswered: How does cerebrospinal fluid cross the arachnoid membrane, a protective barrier separating the brain from the surrounding lymphatic system?
A research team led by Director KOH Gou Young at the Center for Vascular Research within the Institute for Basic Science (IBS), together with collaborators in Korea, Finland, and the United States, has now identified the missing anatomical gateway. The researchers discovered microscopic openings in the arachnoid membrane, which they named “arachnoid fenestrations”, that allow cerebrospinal fluid to pass directly into meningeal lymphatic vessels. The findings reveal the most detailed pathway yet for brain waste clearance and identify a drainage route that progressively deteriorates during aging but can be functionally restored in aged mice.Patients with chronic illnesses are often praised for taking charge of their own healthcare, researching treatments, joining online communities, and becoming informed partners in medical decision-making. But a new study from Bar-Ilan University argues that this growing "patient empowerment" often comes at a hidden cost.
Drawing on in-depth interviews with people living with Parkinson's disease, researchers found that many patients do not actively choose to become experts in their illness. Instead, they feel compelled to do so because healthcare systems leave them with little alternative.
Kyoto, Japan -- Synucleinopathies are a group of neurodegenerative disorders that includes serious conditions such as Parkinson's disease and dementia with Lewy bodies. There are currently no cures for these disorders and treatment is limited to mitigating symptoms. Recently, antibody-based therapies have attracted considerable attention, but alternative approaches are still necessary.
Therapy development for synucleinopathies tends to target the alpha-synuclein protein, αSyn, the abnormal aggregation of which is a hallmark of these diseases. However, targeting this protein using conventional strategies for drug discovery is stymied by the molecule's lack of a stable three-dimensional structure, which cultivates aggregation.
Interested in understanding how abnormal protein aggregation drives neurodegeneration, a team of researchers at Kyoto University had an idea that was both scientifically intriguing and therapeutically promising: could RNA aptamers -- often described as "chemical antibodies" -- directly recognize αSyn's disordered regions and suppress pathological aggregation?
