Yuezhou Chen, M.D, Ph.D, joined School of Life Sciences at Peking University and the Peking-Tsinghua Center for Life Sciences as a Principle Investigator in 2022. Dr. Chen received her Ph.D in Cell Biology from Peking University & National Institute of Biological Sciences, Beijing in 2009. After that, Dr. Chen received medical training in China Academy of Chinese Medical Sciences, and got her M.D in 2014. From 2014-2020, Dr. Chen was a postdoc fellow at Brigham and Women’s Hospital/Harvard Medical School, and she was promoted to Instructor of Medicine at Harvard Medical School in 2020. Dr. Chen has a long-term research interest in investigating how inflammatory contexts and/or environmental factors influence antibody response to antigens in the settings of infection, vaccination, and autoimmunity. She has published original studies in the field of B cell immunology, immune responses after infection and vaccination, as well as antibody repertoire regulation by microbiota. The major focuses of Chen laboratory include understanding the protective immunity in infection and vaccination, the mechanisms of pathogenic autoantibody generation, and how environmental factors influence antibody repertoire in vaccination and autoimmunity.

One of the central questions in immunology is how to recognize self and non-self. B cells produce a large immunoglobulin (Ig) repertoire through V(D)J recombination to recognize the vast diverse antigens. Remarkably, B cells can further evolve through somatic hypermutations in their antibody genes and produce affinity matured antibodies to adapt the evolving pathogens. On the other hand, negative selection occurs in B cell development to remove autoreactive B cells for self-tolerance. The two layers of B cell memories, which include long-lived plasma cells and memory B cells, play crucial roles in pathogen defense and autoimmunity.

How do the hosts generate long-lived antibodies with broad recognition breadth to evolving pathogens in infection and vaccination? How do the pathogenic autoantibodies form in autoimmune diseases? Whether and how modifiable environmental factors (i.e. microbiota) influence B cell differentiation and antibody repertoire formation? Based on these questions, our laboratory will establish mouse models and longitudinal human cohorts, and combine approaches including lineage tracing, single cell RNA sequencing, repertoire sequencing, in-vivo imaging, etc. to carry out studies in the following four areas:

1. The protective immunity in infection and/or vaccination
2. The mechanisms of pathogenic autoantibody generation in autoimmune diseases
3. The modulation of antibody responses by environmental factors
4. The regulation of immune responses by Chinese medicine
