Our research focuses on understanding the fundamental mechanism of innate immunity and its impact on adaptive immunity, inflammation and cancer. Innate immune system mainly relies on pattern recognition receptors (PRRs) to detect invading pathogens and to mount robust anti-microbial immune responses. However, under certain circumstances, PRRs can be self-activated under sterile condition, leading to activation of adaptive immunity and thus triggering either protective immunity or immune disorders in different contexts. The main goal of the lab is to understand the molecular mechanism of innate immune control of adaptive immunity in cancer and inflammation. We aim to: 1) Study the molecular regulation of innate immunity in tumor microenvironment (TME), with the goal of harnessing innate immunity to improve cancer immunotherapy; 2) Understand how innate immunity is initiated in inflammatory environment, and its impact on inflammation and immune disorders.
