Increased VEGFR2 expression on myeloid cells in TB mice was verified at protein level by flow cytometric analysis of BM-myeloid cells, including total CD11b+ myeloid cells, macrophages, monocytic MDSCs (M-MDSCs), and polymorphonuclear MDSCs (PMN-MDSCs) (Figure 2A). Here, ITGAM is linked to tuberculosis.
