To further evaluate alternative macrophage activation in LysMcreSOCS3loxP/loxP mice during experimental TB, we also quantified expression of Il4ra by qRT-PCR in lung homogenates and on the single-cell level by flow cytometric analysis of IL-4Rα expression on CD11b+ F4/80+ lung cells (Figure 3D). This evidence concerns the gene IL4R and tuberculosis.
