Katerina Akassoglou and her team have discovered new mechanisms that control the communication between the brain, the immune system, and the vascular system, and designed novel therapies for neurological diseases. Akassoglou’s lab pioneered studies showing that when the blood-brain barrier is disrupted, the blood-clotting factor fibrinogen can leak into the brain, where it induces neurodegeneration. Their findings indicate that fibrinogen leakage could contribute to a wide range of neurological conditions, including multiple sclerosis, Alzheimer’s disease, traumatic brain injury, and stroke.

Lab Focus

Identifying the functional role of blood-brain barrier disruption in inflammation, neurodegeneration, and repair in neurological diseases.
Searching for new molecular mechanisms that control brain-vascular-immune communication.
Developing new imaging methods for early detection of neuroinflammation and neurovascular alterations in neurological diseases.

Research Impact

Work from Akassoglou’s lab has led to a new way of thinking about neurological diseases by proposing a fundamental mechanism through which cerebrovascular dysfunction impairs the brain and spinal cord. Specifically, they demonstrated that the neurovascular interface is fundamentally changed in neurological disease, often resulting in increased blood-brain barrier permeability that promotes toxic brain inflammation. They identified the blood-clotting factor fibrinogen as a common driver for neuroinflammation and neurodegeneration. They developed the first immunotherapy that blocks the deleterious functions of fibrin and protects from neuroinflammation and neurodegeneration in animal models of multiple sclerosis and Alzheimer’s disease. Therefore, the team’s research has broad impact on the understanding of and ability to treat multiple neurological diseases, including multiple sclerosis, stroke, epilepsy, traumatic brain injury, and spinal cord injury.

Akassoglou’s team continues to investigate the mechanisms at the neurovascular interface that promote neuroinflammation, neurodegeneration, and cognitive decline. They hope to use their discoveries to develop fluid and imaging biomarkers, as well as innovative treatments for devastating neurological diseases.

Katerina Akassoglou, PhD, is a senior Investigator at Gladstone Institutes and a professor of neurology at UC San Francisco (UCSF). A native of Greece, Akassoglou earned both a bachelor’s of science in biology and a PhD in neuroimmunology at the University of Athens, Greece, and trained in neuropathology with Hans Lassmann at the University of Vienna. She completed her postdoctoral work at the State University of New York at Stony Brook and Rockefeller University with Sidney Strickland, and at New York University with Moses Chao. Prior to joining Gladstone in 2008, Akassoglou was an assistant professor of pharmacology at UC San Diego.

Akassoglou has pioneered studies on the mechanisms that control the communication between the brain, immune and vascular systems—and in particular the role of the blood clotting–factor fibrinogen as a common thread in a wide range of neurologic diseases, such as multiple sclerosis, Alzheimer’s disease, and neurodegenerative diseases. She developed cutting-edge imaging tools to study the neurovascular interface and discovered a novel fibrin-targeting immunotherapy and small molecule compounds to protect the brain from pathogenic neuroinflammation. Akassoglou has led multiple international collaborations between academia and pharma, and has given over 200 lectures nationally and internationally. She is active in several scientific organizations, editorial boards, and funding agencies, has published over 95 papers, and is a named inventor on 20 patents and patent applications. Akassoglou is also the scientific founder and board director of the spin-out company Therini Bio.

Akassoglou has received several awards, including the Presidential Early Career Award for Scientists and Engineers, the highest honor bestowed by the US government on outstanding scientists and engineers beginning their independent careers. She has also been presented with the John J. Abel Award, the Dana Foundation for Brain and Immunoimaging Award, the Vilcek Prize for Creative Promise honor, The Marilyn Hilton Award for Innovation in Multiple Sclerosis Research, the R35 Research Program Award by NINDS, and the Barancik Prize for Innovation in MS Research.

How Did You Get Your Start in Science?

“I was inspired by my biology high school teacher. She helped me get a summer internship in an immunology lab and I never looked back.”
