Summary
The opportunistic pathogen Pseudomonas aeruginosa is a common cause of infection in immunocompromised individuals, and often associated with hospital acquired pneumonias. P. aeruginosa activates type I interferon (IFN) signaling through the release of lipopolysaccharide (LPS) from the bacterial surface. Interaction between LPS and the host receptor TLR4 initiates type I IFN through the adaptor proteins TRIF and IRF3. The role of type I IFN signaling during infection is unclear at best; however, defective type I IFN signaling has been linked to the chronic respiratory infections observed in cystic fibrosis patients. This chapter will discuss how type I IFN in activated by P. aeruginosa, the current data describing its contribution to host defense, and the potential contributions of other IFN pathways in the response to this pathogen.
