| abstractText | Caspase-1 (Casp-1) mediates the processing of the proinflammatory cytokines interleukin-1beta (IL-1beta) and IL-18 to their mature forms. Casp-1-deficient mice succumb more rapidly to Salmonella challenge than do wild-type animals. Both Casp-1 substrates, IL-18 and IL-1beta, are relevant for control of Salmonella enterica serovar Typhimurium. We used IL-18-/- and IL-1beta-/- mice in addition to administration of recombinant IL-18 to Casp-1-/- mice to demonstrate that IL-18 is important for resistance to the systemic infection but not for resistance to the intestinal phase of the infection. This suggests that IL-1beta is critical for the intestinal phase of the disease. Thus, we show that Casp-1 is essential for host innate immune defense against S. enterica serovar Typhimurium and that Casp-1 substrates are required at distinct times and anatomical sites. |
