Regulation of host responses to viruses; host-pathogen interaction and systems biology; emerging zoonotic viruses
Ongoing projects in Dr. Xing's Laboratory
Research interests in our laboratory are focused on studying the regulation of host responses to viruses, especially those causing emerging infectious diseases in animals and human, and elucidating the mechanism of host-virus interaction and viral pathogenesis. The pathogens studied in our lab include members of orthomyxoviruses and bunyaviruses such as avian and swine influenza viruses and novel bunyaviruses.
Characterization of Novel Mechanisms for Immune Evasion by Bunyaviruses
Severe fever with thrombocytopenia Syndrome (SFTS), an emerging tick-borne infectious disease, is caused by a new bunyavirus (SFTSV), which is similar to the Heartland virus identified in Missouri in 2011. The viruses infect a variety of agricultural and wildlife animals as well as human. Studies in our lab initially showed that SFTSV inhibits host innate immunity and later found that viral nonstructural protein NSs interacts with TBK1, a key kinase for IFN signaling, and sequesters TBK1 together with IKKe and IRF3 into viral inclusion bodies formed by NSs itself, resulting in the suppression of host antiviral IFN induction, a novel mechanism of viral immune evasion, as spotlighted by Journal of Virology and recommended to Faculty of 1000Prime Report for its “special significance”.
Regulation of Host Responses to Avian and Swine Influenza Viruses
We have deciphered the mechanism about the regulation of host proinflammatory and antiviral cytokines in immune cells and differentiated bronchial epithelial cells of avian and human species by MAP kinases and NFkB signaling, which also play a role in the replication of avian influenza viruses in the host. Genomic and cell biology approaches are carried out, together with reverse genetics to generate mutant influenza virus strains, to characterize how viral nonstructural proteins including NS1 and PB1-F2 interact with cellular components essential to signaling pathways in controlling host cytokine induction, apoptosis and viral pathogenesis in animals and human.
