Over the recent years, the zebrafish (Danio rerio) has rapidly gained popularity as a model for inflammatory and infectious diseases. The zebrafish offers unique advantages in studying pathogen-host interactions, including easy genetic manipulations and real-time non-invasive observation of the infection progress. My recent work used the zebrafish as a model to understand how host immune cells, especially neutrophils, respond to Pseudomonas infection. I have shown that a localized Pseudomoas infection is an opportunistic infection which is only pathogenic in fish with impaired neutrophil functions. I found that neutrophils respond to infection and tissue injury through distinct signaling mechanisms. Finally, I have characterized the kinetics of a systemic neutrophil activation induced with a local infection and demonstrated the role of cxcr2 signaling in this systemic response. My future studies will characterize the detailed mechanisms how leukocytes respond to infections as well as the interplay of the infectious agents and the host that would influence host outcome.
