Research Interests

  • Avian antiviral innate Immunity & Signal Transduction

SUN's primary research interest is in the antiviral innate immune signaling dependent on an adaptor molecule designated as STING in chicken. Because of the significant differences in the innate immune response between chicken and mammals, the novel innate immune signal molecule and signal transduction pathways in chicken are being revealed, and the molecular mechanism of antiviral effect are being elucidated.


  • The structure and function of phage and phage-encoded bactericidal proteins

SUN's secondary research interest is in the molecules and mechanisms of bacteriophage lysis, much of his work focus on the structure & function of phage encoded lysin to degrade the bacteria and the small membrane protein holin to punch holes in the bacterial cell membranes. SUN's Lab is currently dedicated to using bacteriophages hosted by streptococcus suis, Staphylococcus aureus, as well as E.coli and its encoded lysin to prevent the antibiotic-resistant strain extracellular and intracellular infections or disrupt the bacterial biofilms.
