The data (Figure 11 A–C) showed 2.41 fold (p = 0.0003 vs infected control) and 2.16 fold (p<0.0001 vs infected control) reduction respectively in the intracellular amastigote number and percent of infected cells, when stimulated by IFNγ at 4 hr post infection, along with 2.51 fold (p = 0.0009) enhanced generation of NO. This evidence concerns the gene IFNG and infection.
