Importantly, treatment significantly reduced both the frequency (Fig 6D) and absolute number (Fig 6E) of Ly6C+CCR2+CX3CR1+/- inflammatory or Ly6C+CCR2-CX3CR1+ inflammatory monocyte derived cells in LmLm mice, demonstrating that IFN-γ drives a proportion of monocyte recruitment during secondary infection. This evidence concerns the gene IFNG and infection.
