Remarkably, the treatment of EG.7 TB mice with VSSP reduced to undetectable levels the cross-presentation of OVA, as a model tumor antigen, by splenic CD11b+Gr1+ cells, comparable to the values obtained for MDSCs isolated from EL4 TB mice, a control tumor lacking OVA expression (Figure 7A and B). This evidence concerns the gene ITGAM and tuberculosis.
