We found that the percentages of Gr‐1+ cells in the CD11b+‐gated cell populations in the splenocytes of Mavs–/– (sensitive) mice were much higher than those of Mavs–/–Il6–/– (resistant) mice after N67C infections, while the basal levels of the Gr‐1+ (Ly6C/Ly6G) cells were similar between Mavs–/– and Mavs–/–Il6–/– mice (Figure 6A). This evidence concerns the gene IL6 and infection.
