Seasonal influenza A virus (IAV) infections and their associated respiratory diseases are the cause of an estimated 650,000 deaths each year, according to the World Health Organization. The zebrafish (Danio rerio) is a powerful vertebrate model to study innate immune function and host-pathogen interactions as the function of neutrophils and other phagocytes can be characterized in vivo. Preliminary studies have shown an increase in neutrophil respiratory burst activity to eliminate the invading pathogen, yet little is known of all of the mechanisms involved in neutrophil function. The NADPH oxidase complex, of which neutrophil cytosolic factor 1 (Ncf1) is a key …

The CDC estimated that seasonal influenza A virus (IAV) infections resulted in 490,600 hospitalizations and 34,200 deaths in the US in the 2018-2019 season. The longterm goal of our research is to understand how to improve innate immune responses to IAV. During IAV infection, neutrophils and macrophages initiate a respiratory burst response where reactive oxygen species (ROS) are generated to destroy the pathogen and recruit additional immune cells. While ROS molecules, such as hydrogen peroxide, help clear the virus, the signaling cascade can also lead to excess neutrophil recruitment, hyperinflammation, and tissue damage. Regulatory mechanisms that trigger overactivation of neutrophils …
