- Abstract
- Immune defense responses against Pseudomonas aeruginosa infection play an important role in maintaining homeostasis in the human body. Previously, we reported that expression of the bradykinin receptor (BR) is induced in response to P. aeruginosa infection. However, the factors responsible for the induction was uncertain. Here, we found that the type III secretion system (T3SS) is responsible for the induction of BR expression, and nucleoside diphosphate kinase (Ndk), as a novel T3SS effector, mediates the upregulation. The Ndk-mediated expression of BR was not induced by fliC mutant treatment, indicating the involvement of flagellin, one of the well-known pathogen-associated molecular patterns (PAMPs). Taken together, this study demonstrated that Ndk cooperates with flagella in the development of defense responses against P. aeruginosa infection. © 2014, The Microbiological Society of Korea.
