(A-B) Survival curves (A) and weight loss over time (B) of Casp1/11+/+Ifnar
-/- (Caspase 1/11 WT), Casp1/11
+/-Ifnar
-/- (Caspase 1/11 Het), or Casp1/11
-/-Ifnar
-/- (Caspase 1/11 KO) littermates infected intravenously with 3 x 105 PFU of DENV2 D220. Survival was monitored over 14 days. Weight loss was monitored over 9 days. Numbers in parentheses indicate the numbers of mice in each group. Statistical significance was determined by Mantel–Cox log-rank test (A) or two-way ANOVA with Holm-Sidak’s multiple comparisons test (B). (C-D) Survival curves of Nlrp3
