Further analysis of the cellular composition of the recruited cells showed that, compared to Mtb-HT1, all three Mtb-LT infected mice had significantly increased numbers of CD8+ T cells and CD11b+CD11c+ recruited macrophages while B220+ B-cells, CD11bhiLy6G+ neutrophils were increased in Mtb-LT1 and Mtb-LT2 infections. This evidence concerns the gene ITGAM and infection.
