The inflammasome is thought to function as a cytosolic surveillance system against intracellular pathogens. However, we report that Pseudomonas aeruginosa, an extracellular pathogen responsible for acute lung infection, relies upon inflammasome activation to persist and worsen disease. Specifically, we show that loss of either NLRC4 expression or type-3 secretion system (T3SS)-driven activation of NLRC4, surprisingly, resulted in a robust Th-17-like immune response that enhanced bacterial clearance and attenuated virulence independently of exotoxins. This Th-17-like response correlated with marked upregulation of antimicrobial peptides and was suppressed by either neutralization of IL-17A or exogenous IL-18 administration in vivo. Together,...
