New Drug Shows Promise in Alzheimer’s Disease Treatment by Protecting the Blood-Brain Barrier
Table of Contents
Cleveland,OH – A collaborative team of researchers has identified a promising new drug candidate for Alzheimer’s disease,offering a possibly groundbreaking approach to treatment. The findings, published May 21 in Proceedings of the National academy of Sciences, suggest that protecting the blood-brain barrier could be a key strategy in preventing neurodegeneration and cognitive decline. Worldwide, over 55 million individuals are affected by dementia, with Alzheimer’s disease being the most prevalent cause [[1]].
The Blood-Brain Barrier: A New Therapeutic Target
Traditionally, Alzheimer’s research has centered on targeting neurons directly. This study, however, shifts focus to the blood-brain barrier (BBB), a crucial protective network that regulates the passage of substances into the brain. The BBB acts as a gatekeeper, allowing essential molecules to enter while blocking harmful elements like bacteria and viruses.

The integrity of the BBB is increasingly recognized as an early indicator of neurodegenerative diseases, including Alzheimer’s and traumatic brain injury.
Researchers discovered that an enzyme called 15-PGDH (15-hydroxyprostaglandin dehydrogenase) is highly concentrated within the BBB. They found elevated levels of this enzyme in both mouse models and human patients with Alzheimer’s, traumatic brain injury, and age-related cognitive decline, indicating a detrimental impact on BBB function.
SW033291: Blocking the Enzyme for brain Protection
To address this, the team developed SW033291, a drug designed to block the activity of 15-PGDH within the BBB. Originally conceived for unrelated applications – specifically, activating stem cells to repair tissue damage in colitis and bone-marrow transplants – the drug demonstrated unexpected benefits in protecting brain health. “Finding that blocking 15-PGDH also blocks brain inflammation and protects the BBB was an exciting new finding,” stated Sanford Markowitz, a co-lead researcher and Ingalls Professor of Cancer Genetics at Case Western Reserve University.
In mouse models, SW033291 effectively preserved the integrity of the BBB, preventing neurodegeneration and maintaining cognitive function.Notably,the drug did not significantly alter amyloid plaque levels in the brain,a key distinction from many recently approved Alzheimer’s treatments that focus solely on amyloid removal. “Inhibiting 15-PGDH thus offers a completely new approach for AD treatment,” Markowitz explained.
Promising Results Beyond Alzheimer’s
The protective effects of SW033291 extended beyond Alzheimer’s disease.The drug also demonstrated efficacy in protecting mice from neurodegeneration and cognitive impairment following traumatic brain injury, even when administered a day after the injury occurred. This suggests potential applications for treating a range of brain injuries and neurological conditions.
The research was a collaborative effort involving investigators from Case Western Reserve University, University Hospitals, and the Louis Stokes Cleveland VA Medical Center. Andrew Pieper,a psychiatrist and neuroscientist at Case Western Reserve School of Medicine,co-led the study and emphasized the potential for a safe and effective new treatment. “Our findings suggest an effective new way to safely prevent neurodegeneration and cognitive impairment in Alzheimer’s disease by directly protecting the blood-brain barrier,” Pieper said.
Pro Tip:
Maintaining a healthy lifestyle, including regular exercise and a balanced diet, can contribute to overall brain health and potentially reduce the risk of neurodegenerative diseases.

Alzheimer’s disease is a growing global health concern, with the number of affected individuals projected to rise dramatically in the coming decades. Current treatments primarily focus on managing symptoms, but there is an urgent need for therapies that can slow or prevent disease progression. Research into the underlying mechanisms of Alzheimer’s, such as the role of the blood-brain barrier, is crucial for developing effective interventions. The amyloid hypothesis, which posits that amyloid plaque buildup is the primary driver of Alzheimer’s, has been the dominant focus for years, but recent clinical trial failures have prompted a reevaluation of this approach [[2]]. This new research offers a compelling alternative by targeting a different aspect of the disease process.
Frequently Asked Questions about Alzheimer’s and the New Drug
- What is Alzheimer’s disease? Alzheimer’s disease is a progressive brain disorder that gradually destroys memory and thinking skills.
