Biosketch

Dr. Guangming Li received his Ph.D. degree in Agronomy from Nanjing Agriculture University and did his post-doctoral training in Virology and Immunology at University of North Carolina at Chapel Hill (HIV-1 immune pathology) in Dr. Lishan Su's lab.  From 2014 to 2020, Dr. Li continued his research in chronic viral infection induced immune pathology and immune therapy in the context of HIV infection as Research Associate. In October 2020, Dr. Li joined The Institute of Human Virology at UMSOM as Assistant Professor and continues his research to mechanistically understand HIV immune pathogenesis and develop novel therapeutic strategies for HIV-1 cure in either humanized mice in vivo or cell culture system in vitro. Dr. Li also works on developing novel anti-HIV CAR-T or CAR-NK cells therapy for treating chronic diseases including HIV-1 infection and cancer.

Research Interests

  • Novel HIV-1 therapeutic strategy in humanized mouse models: Our group at UMB is one of the top professionals to use human hematopoietic stem cells and human fetal lymphoid tissue engrafted humanized mouse models to study HIV-1 infection, pathogenesis and therapy. We were the first to study HIV-1 immuno-pathogenesis and therapy in the new generation of humanized Rag-C double knockout mouse or NSG model (DKO-hu and NSG-hu HSC mice). Since joining the faculty at UMB in year 2020 and working in Dr. Lishan Su’s lab, I have focused elucidating mechanisms of HIV-1 reservoir persistence and developing therapeutics for HIV infection in humanized mice in vivo.
  • The HIV-1/pDC/IFN-I axis in HIV-1 infection, pathogenesis and cure: The precise role of pDC in HIV-1 pathogenesis is not clear. The conflicting reports in HIV-infected patients highlight the importance of studying the interaction between HIV-1 and pDC cells in relevant models. The human immune system engrafted humanized mouse model is a powerful tool to study human pDC development and function during HIV-1 infection in vivo. Most importantly, we have developed a critical anti-pDC mAb that efficiently depletes human pDC in vivo to investigate pDC-associated HVI-1 pathogenesis. Our studies show that HIV-1 can efficiently activate and productively infect human pDC in vivo. In addtion, pDC are the major (or only) cells producing type I interferons during HIV-1 infection, which contribute to suppressing HIV-1 replication in vivo. Most strikingly, depletion of pDC during HIV-1 infection resolves HIV pathogenesis in the presence of elevated levels of HIV infection. These findings suggest that pDC play a critical role in contributing to HIV pathogenesis and disease progression. Modulating pDC and IFN-I provides a novel approach to treating HIV-induced diseases.
