Cytokine analysis of blood plasma samples collected 4 hours after infection revealed an increase in concentrations of IL-1α, IL-6, the CXC chemokine KC, G-CSF, MCP-1, and the CC chemokine eotaxin in WT but not in Trpm5–/– mice compared with concentrations before infection (Figure 9, H–J, and Supplemental Figure 14, D–F). Here, IL6 is linked to infection.
