IFNG and infection: Again, differences in amount of inflammatory cytokines (IFN-γ and IL12) elicited in response to LM infection and pathogen load were seen between inbred and outbred mice (Figure S5 in Supplementary Material), but differences in magnitude of effector CD8 T cell responses in individual outbred mice appeared unlikely to be caused by differences in infection or amount of inflammation elicited in response to infection in individual outbred mice.
