Both bone marrow-derived macrophages (CD11b+F4/80+) and alveolar macrophages (CD11b−CD11c+) expressed Adrb2, and Adrb2 in bone marrow-derived macrophages was slightly upregulated in the lungs of TB mice, but not in alveolar macrophages (Figure 5G,H). This evidence concerns the gene ITGAM and tuberculosis.
