Dr. Yuntao Wu is a professor at the National Center for Biodefense and Infectious Diseases, George Mason University, Manassas, Virginia, USA. He received his Ph.D. from the Department of Microbiology and Immunology at Queen’s University, Kingston, Ontario, Canada, and his postdoctoral training at NIH, Bethesda, Maryland, USA. Dr. Wu studies HIV infection of blood CD4 T cells and macrophages (Science, 2001, 293:1503-6), mainly focusing on the role of chemokine- and HIV-1-mediated G-protein signaling and actin dynamics in HIV infection and pathogenesis (Cell, 2008, 134,782; Science Advances, 2019, 5:1,aat7911). Currently, his lab also studies the mechanisms of PSGL-1 restriction of HIV infection (Nature Microbiology, 2019, 4:813-25).
