Expression of Il-11 and Cxcl-14 by lung macrophages and fibroblasts isolated from TB-susceptible I/St mice and TB-resistant A/Sn mice. Normalized Il-11 and Cxcl-14 gene expression levels are shown as severalfold differences relative to Hprt gene expression. (A) Lung macrophages (gray bars) express higher levels of Il-11 than lung fibroblasts (hatched bars) from both I/St and A/Sn mice. (B) Lung fibroblasts (hatched bars) express higher levels of Cxcl-14 than macrophages (gray bars) from mice of both strains. In each experiment, syngeneic lung macrophages or lung fibroblasts extracted from several mice were pooled. Expression levels of Il-11 and Cxcl-14 were measured by quantitative RT-PCR. Results are expressed as means (±standard errors) of triplicate assays from one of three experiments with similar results.
