Tsuneya Ikezu, MD, PhD
Location: L-606 B
Dr. Tsuneya Ikezu completed his undergraduate education at University of Tokyo School of Science and Arts, Japan. He earned his M. D. in 1991 and Ph.D. degrees from University of Tokyo School of Medicine in 1997. He joined the Boston University School of Medicine’s Department of Pharmacology and Experimental Therapeutics with a joint appointment in the Department of Neurology in 2010 as a Professor. Dr. Ikezu also leads the Laboratory of Molecular Neurotherapeutics. He joined the BU ADC in March 2011.
Dr. Ikezu’s research interests are focused on the role of neuroinflammation in the pathophysiology of dementia and as a potential therapeutic target of Alzheimer’s disease, HIV-associated dementia, and more recently chronic traumatic encephalopathy and encephalomyelopathy. He also studies enzymes that induce phosphorylation and aggregation of neurological disease-associated proteins, such as Alzheimer’s disease, HIV-associated dementia, and frontotemporal dementia.
Dr. Ikezu facilitates basic and translational research on neuroinflammation-related neurodegenerative disorders for BU ADC.
Dr. Ikezu is a past recipient of the Vada Oldfield Alzheimer’s Research Award in 2000, the UNMC Distinguished Scientist Award in 2009, and the UNeMed Research Innovation Award in 2009. He serves on several editorial boards, including PLoS One.
