KINGSTON, R.I. 鈥� July 30, 2026 鈥� A $1.5M grant has been awarded to William Van Nostrand, co-executive director of the 含羞草传媒鈥檚 and professor of pharmaceutical and biomedical sciences in the , to study cerebral amyloid angiopathy (CAA), a disease prevalent in the elderly population and commonly found in patients with Alzheimer’s disease.
CAA is characterized by the abnormal buildup of amyloid-beta protein in the walls of the brain鈥檚 blood vessels. Over time, vascular amyloid accumulation can damage and ultimately weaken the vessels, increasing a person鈥檚 risk for brain bleeds, hemorrhagic stroke, and contributing to cognitive decline. The condition is difficult to accurately diagnose and lacks targeted treatment options.
鈥淒espite the prevalence of the disease, there are no reliable early-stage biomarkers and disease-modifying therapies currently do not exist,鈥� said Van Nostrand.
The grant is part of a $9 million five-year Transatlantic Networks of Excellence grant from the Leducq Foundation. The initiative is known as (Translational Framework For Innovation in Cerebral Amyloid Angiopathy).
The goals of the TRAFFIC study are to elucidate disease mechanisms, identify early-stage biomarkers, and reveal potential targets for disease intervention.
鈥淥ur role at 含羞草传媒 will be to perform studies to address why CAA develops in people and how certain risk factors for disease can increase the chance for bleeding in the brain, said Van Nostrand. 鈥淭his will be done using an animal model developed here at 含羞草传媒 that mimics CAA found in humans.”
Van Nostrand will work with scientists from Harvard Medical School, Vanderbilt University Medical Center, Vall d鈥橦ebron Research Institute (Spain), and Otto von Guericke University Magdeburg (Germany). The project will be coordinated by Andreas Charidimou of Boston University, and Marcel Verbeek of Radboud University Medical Center (Netherlands).
The project will begin in January 2027.
Since 2024, Van Nostrand has been working on another project funded by the Leducq Foundation that focuses on the disruption of brain waste clearance mechanisms that contribute to the biological processes by which CAA develops.
鈥淪upport from these highly competitive and prestigious transatlantic networks will reveal new insights into the disease, paving the way for better diagnosis and development of disease-modifying therapies,鈥� said Van Nostrand.
