In vivo expression of IL-12p40, CCL17, and CXCL10. Lung CD11c⁺ cells or CD11b⁺ cells were isolated 2 and 3 weeks following aerosol infection of mice with M. tuberculosis and assayed for expression of IL-12p40 (A), CCL17 (B), and CXCL10 (C) by real-time PCR. Lung CD11b⁺ cells from uninfected mice (UT) were used as the calibrator. Lungs from three mice were pooled for each experiment and assayed in triplicate. Two separate experiments were performed for the 2-week time-point and one experiment for the 3-week time-point.
