Our long-term objectives are to decipher the anti-bacterial or anti-viral effect of intracellular metabolism. Our research is focused on understanding the pathogenesis of pathogens (bacteria and virus) and how innate immunity or cell-autonomous immunity resists microorganisms.
Some specific research interests of the lab include:
1. Pathogenesis of Salmonella.
2. Immune responses to Salmonella infection.
3. Screening and identification of new antimicrobial metabolites.
Dr. Meixin Chen earned her Ph.D. in Cell Biology from Sun Yat-sen University in 2018. She joined the laboratory of Dr. Jorge E. Galán, a member of the USA National Academy of Science, at Yale University School of Medicine as a postdoctoral researcher, during which she focused on understanding of how pathogens interact with their hosts. Dr. Meixin Chen and her colleagues found that the mitochondria-derived metabolite itaconate targeted Salmonella containing vacuoles. This study placed the intracellular metabolism in the center of cell-autonomous defenses and was published in Science. Dr. Meixin Chen has been studying innate immune responses for many years, and in addition to Salmonella, she has worked on how DNA virus or RNA virus interacts with their hosts. Dr. Meixin Chen, as a first author, has published several articles in Science, Molecular Cell, and Advanced Science.
