Figure 6. Signs of alternative macrophage activation in the lung transcriptome of macIL-10tg mice after Mtb infection.
(a) Gene lists identified in Fig. 5A as upregulated differentially in FVB and macIL-10tg mice at d42 after infection were entered into the Genomatix Bibliosphere literature-based data mining tool. Shown are the z-score values indicating the degree of co-citation of selected cell types with the gene list from both genotypes. Higher z-score values indicate stronger enrichment. (b) Changes in expression of selected genes associated with alternative macrophage activation during Mtb infection of FVB and macIL-10tg mice were visualized using hierarchical clustering of z-score normalized average expression values. Similarity between experimental conditions and patterns of individual genes is indicated by dendrograms. Gene symbols are given.
