Comparison of host immunity gene expression in C57BL6/J macrophages infected with wild-type Mycobacterium tuberculosis or Mtb:Δ-sigH, an attenuated mutant, and transfected with interleukin 6 (Il6) small interfering RNA (siRNA). A, Expression of Ly6 genes. B, Expression of Cish, Csf1r, Ifitm6, Cxcl2 genes. Expression values are shown for DNA microarray experiments. Values represent responses that were statistically different between the Il-6 siRNA vs scrambled negative control treatments. *P < .05; **P < .01.
