Research Areas
Our research aims to identify biological targets for the prevention and treatment of infectious diseases. The laboratory focuses on understanding the pathogenic mechanisms of microbial pathogens within the host and elucidating how host immunity and cellular metabolism defend against infection at the molecular level.
Our major research directions include:
1. Pathogenic mechanisms of microbial pathogens
2. Molecular mechanisms of host defense against microbial infection, with an emphasis on immune and metabolic regulation
3. Discovery and characterization of novel antimicrobial molecules
We foster a collaborative, supportive, and intellectually stimulating research environment where members work together and grow together. We warmly welcome students and researchers who are interested in infection biology, immunology, and metabolism to join our group.
Highlights
Dr. Meixin Chen joined Shenzhen Bay Laboratory as a full-time Distinguished Research Fellow at the Institute of Infectious Diseases in 2021 and serves as a PhD supervisor. Dr. Meixin Chen has long been dedicated to studying the interactions between host immunity and pathogen infection. Dr. Meixin Chen’s research first revealed the important role and regulatory mechanisms of ubiquitination of the DNA sensor cGAS in host defense against pathogen infection. In addition, Dr. Meixin Chen was among the first to use metabolite-sensing reporters to uncover an itaconate-mediated antibacterial pathway in host cells. These studies have provided important insights into the mechanisms of pathogen virulence and host defense, contributing to a deeper understanding of host-pathogen interactions. Dr. Meixin Chen has published as corresponding author or first author in leading journals, including Science, Molecular Cell, Nature Microbiology, Advanced Science, and Nature Communications. Dr. Meixin Chen has also received funding from national, provincial, and municipal research programs.
