In contrast to CY+TLRa-treated mice, assays of splenocytes from untreated TB mice revealed that neither UF splenocytes nor Gr1+ myeloid subpopulations (Gr1hi or Gr1dim) displayed tumoricidal properties, even following in vitro exposure to CpG, IFNγ or CpG+IFNγ (Supplemental Figure S5, columns 2 and 3). This evidence concerns the gene IFNG and tuberculosis.
