ITGAM and tuberculosis: Corresponding cells in TB mice also markedly increased, in which the CD11b+Gr-1+ cells accounted for 13.9% of the spleen cells, equivalent to 20.2±1.7×106 CD11b+Gr-1+ cells in a moderate tumor (4.1 g), an 11-fold increase (**P<0.01 versus non-tumor-bearing animals) (Fig. 1D).
