In the absence of TLR5 and inflammasome recognition, FliC’s D2/D3 domains are essential for secondary IgG1 and IgG2c anti-flagellin responses. TLR5−/−xCasp1/11−/− mice were immunized with 30 μg WT FliC (n = 11), FliCΔNaip5/6 (n = 4), or FliCΔTLR5 (n = 5), FliCΔTLR5/Naip5/6 (n = 3), FliCΔD3 (n = 8), or FliCΔD0/D1 (n = 10) on day 0 and 21, and sera were collected on days 14 and 35. Day 14 and 35 sera were analyzed for IgG1 (A) and IgG2c (B) Ab responses against WT FliC, FliCΔNaip5/6 or FliCΔTLR5, FliCΔTLR5/Naip5/6 FliCΔD3, or FliCΔD0/D1 by ELISA. Statistical analyses were done on day 14 and 35 using one-way ANOVA with multiple comparison posttest. *p < 0.05, ***p < 0.001. ns, not significant. Américo H. López-Yglesias et al.
