Education and Training

1985-1989: B.S. - Sichuan University, Chengdu, Sichuan, China (Genetics)

1989-1992: M.S. - Sichuan Industrial Institute of Antibiotics, The State Food and Drug Administration (SFDA), Chengdu, China (Microbiology)

Dr. Yuxing Li obtained her PhD degree from Iowa State University majored in Genetics. After a postdoc training under the supervision of Dr. Susan Carpenter at Iowa State University on lentivirus pathogenesis and persistence, she joined Dr. Richard T. Wyatt’s laboratory in the Vaccine Research Center (VRC), NIAID/NIH as a research fellow.  At VRC, Dr. Li interacted and worked closely with scientists working on HIV structural biology, virology, and immunology, including Peter Kwong, Mark Connors, Mario Roederer, and John Mascola.  During the training at VRC, Dr. Li started to develop an integrated research program focused on HIV vaccine rational design based on HIV envelope glycoprotein structural and immunologic analysis.  In 2010, Dr. Li joined the IAVI Neutralizing Antibody Center at The Scripps Research Institute as an Assistant Professor of Immunology, based in La Jolla, California. In 2014, Dr. Li relocated her laboratory to the Institute for Bioscience and Biotechnology Research (IBBR) in Rockville, Maryland and affiliated with Department of Microbiology and Immunology, University of Maryland School of Medicine.

Research Interests

The long-term research interests of my lab include B cell response to viral infection, HIV-1 vaccine development and HIV pathogenesis and anti-viral therapy. Current, research efforts focus on investigating the development of B cell response targeting HIV envelope glycoproteins (Env) and searching for novel immunogen and immunization regimens to better elicit broadly neutralizing antibodies. Such studies aim to develop a better understanding of the mechanism underlying protective immunity and contribute to the development of a broadly effective HIV-1 vaccine. Rational design of Env immunogens and immunization regimens based on the B cell response analysis are actively progressing in my lab. Research on the reconstitution of immunity after anti-viral therapy and novel anti-viral approach development is also ongoing.

Therapeutic antibodies for Ebola virus infection had protection breadth limited to Zaire Ebola strain, but not effective for other pathogenic strains such as Sudan and Bundibugyo.   Recently, we successfully isolated broadly neutralizing antibodies from Ebola virus experiment vaccine immunized non-human primate animal and developed a pan-Ebolavirus therapeutic antibody cocktail for pre-clinical trial in non-human primate model. Future work will focus on delineating B cell response to the filovirus glycoproteins to inform vaccine design aimed to elicit broadly protective antibody response.

R01 AI126587                                                              



Evolution of anti-filovirus B cell responses and mechanisms of protection

In this proposal, we seek to study the response of monkeys and humans to filovirus vaccines to determine the features of a vaccine response that would protect against all filoviruses. The proposed study is also likely to generate novel immunotherapeutic antibodies for treatment of filovirus infections.
