Figure Lengend Snippet: ( A-B ). Cell death of THP-1 macrophages upon infection with S. flexneri 2457T ( A ), or electroporation with S. enterica serovar Minnesota LPS ( B ), measured by LDH release, as percentage of Triton X-100-induced cell lysis. N ≥ 4 biological replicates. ( C-D ). NLRP11 is required for the processing of CASP4 and gasdermin D (GSDMD) induced by S. flexneri infection ( C ), or S. enterica LPS electroporation ( D ). CASP4 is required for GSDMD processing induced by S. flexneri infection ( C ), or S. enterica LPS electroporation ( D ). Processing of CASP4 yields a p32 and/or p20 polypeptide, and processing of GSDMD yields a p30 polypeptide. Representative western blots. Molecular weight markers in kDa. DKO, NLRP11 −/− CASP4 −/− double knockout. Mean ± SEM. Two-way ANOVA with Tukey’s post hoc test *, P<0.05; **, P<0.01; ****, P<0.0001.
