Research Areas:

A balanced immune homeostasis is crucial to health. Both overactive and insufficient immune responses create problems. Excessive or chronic immune activation is known to contribute to pathogenesis of various diseases, like obesity, diabetes, rheumatic diseases, autoimmunity, lethal cytokine storms etc. Conversely, insufficient immune response impair defense against pathogens, and even contribute to tumorigenesis. Over the past decades, both repressive and active immunoregulators have been found in emission of injured tissues and stressed/dying cells, but the relevant understanding of their immunogenicity remains limited, and limited attention has been dedicated to comprehensively identify and characterize these stressed/dying cells derived immunoregulators. Thus, we will utilize approaches including biochemical, cellular, molecular, multi-omics etc. to identify and characterize potent immunoregulators emitted from stressed/dying cells, decipher their biogenesis and physio-pathological functions, aim to provide novel strategies and targets for diagnosis, treatment, and prognosis of inflammation relevant diseases.

We have demonstrated extrachromosomal circular DNA (eccDNA) of a few hundred bp as a circularized product of apoptotic DNA fragments and shows potent immunostimulatory activity in vitro. Due to technical challenges, physio-pathological roles of eccDNAs remain to be explored, and the same goes with their regulations in vivo. To address these questions, we determine to crash technical obstacles via developing novel tools and strategies, eventually to reveal the nature of eccDNAs, particularly under pathological contexts.
