Cytokine levels in sera, but not in macrophages, are significantly decreased in macrophage-specific Slc39a10fl/fl;LysM-Cre+ mice. (A) The indicated cytokines levels were measured in the sera of Slc39a10fl/fl;LysM-Cre+ and control mice with and without LPS stimulation (n = 5 mice per group). (B) mRNA levels of the indicated cytokines were measured in the spleen of Slc39a10fl/fl;LysM-Cre+ and control mice following LPS stimulation (n = 5 mice per group). (C and D) Protein (C) and mRNA (D) levels of TNF-α, IL-6, and IFN-β were measured in BMDMs of Slc39a10fl/fl;LysM-Cre+ mice and control mice at the indicated times following LPS stimulation (n = 3 mice per group). NT, no treatment. A, C, and D were analyzed by ANOVA, B by t test. *P < 0.05.
