Dysregulated inflammasome activation contributes to respiratory infections and
pathologic airway inflammation. Through basic and translational approaches
involving murine models and human genetic epidemiology, we show here the
importance of the different inflammasomes in regulating inflammatory responses in
mice and humans with cystic fibrosis (CF), a life-threatening disorder of the
lungs and digestive system. While both contributing to pathogen clearance, NLRP3
more than NLRC4 contributes to deleterious inflammatory responses in CF and
correlates with defective NLRC4-dependent IL-1Ra production. Disease
susceptibility in mice and microbial colonization in humans occurs in conditions
of genetic deficiency of NLRC4 or IL-1Ra and can be rescued by administration of
the recombinant IL-1Ra, anakinra. These results indicate that pathogenic NLRP3
activity in CF could be negatively regulated by IL-1Ra and provide a
proof-of-concept evidence that inflammasomes are potential targets to limit the
pathological consequences of microbial colonization in CF.
