The Rosen laboratory focuses on understanding interactions between bacteria and human neutrophils. Recent emphasis has been on using the bacterial response to neutrophil phagocytosis (mRNA expression profiles) to reflect bacterial prioritization of the multifactorial threats to microbial survival within the neutrophil phagosome. Upregulated genes are used to identify systems that may be important for microbial survival under these conditions. Targeted gene deletions are the used to evaluate the importance of the gene products for microbial survival in neutrophils and virulence in a murine infection model. Dr. Rosen collaborates with Dr. Klebanoff.
