Professional Experience

Dr. Ligong Chen obtained his BS from Nankai University in Chemistry in 1997. He completed his PhD from University of California at Berkeley and postdoctoral training from UCSF in 2006 and 2011, respectively. Currently, He is tenured professor in pharmacology and toxicology in School of Pharmaceutical Science at Tsinghua University. His research area is the SLC transporter physiology and pharmacology. His lab is working on various transporters‘ roles in human diseases and molecular mechanism of drug toxicity. Using advanced molecular and genomic approaches with cell and animal models, Dr. Chen has discovered several important transporters’ physiological substrates and their functions in fatty liver, cancer, neurological disorders and immunity. He has published more than 50 publications including those on Nature Genetics, Immunity, Gut, Hepatology, Nature Communications, PNAS and Cell Reports et al. He has been selected to national 1000 talent program and national leading scientists in innovation and technology and won many awards like the Wuxi Apptec Chemical Biology Award and Excellence in Teaching and of Tsinghua University.

Research Interests

· The impact of important SLC transporters on the immune system for the polarization, differentiation and antibody production of immune cells for the development of immunomodulatory drugs;      
· Mechanisms of neuronal regeneration, remyelination and neurotransmitter homeostasis regulation by important SLC transporters in the nervous system for potential therapeutic strategies for neurological diseases;     
· Regulation of metabolic homeostasis by important SLC transporters in liver and adipose tissue with their application in fatty liver, liver cancer and metabolic diseases.    
     

Scientific Contributions 

Dr. Chen identify that thiamine (Vitamin B1) is a primary endogenous substrate of OCT1 and define its significant role in lipogenesis and glycogenesis in mouse models. Pharmacogenomics of transporters is another important aspect of our studies. He also identified and characterized the genetic variants from type 2 diabetes patients or healthy volunteer of OCT1 and OCT3, which revealed important information on the metformin pharmacogenomics. During his Ph.D. study, he discovered that structural similar GABA receptor antagonist binding at the same site.
