Casp1/11–/–Casp8+/–Ripk3–/– mice retain Caspase-8 function downstream of both NLRC4 and TNFα (Figure 2—figure supplement 2) and based on our previous experiments with Casp1/11–/– mice (Mitchell et al., 2020), we expected that these mice would be resistant to infection. This evidence concerns the gene TNF and infection.
