Our data shows that liver CD4 T cells and DCs were the source of IL-10 on day 21 of infection (Figure 6) and, surprisingly, on day 21 after infection (Figure 6), liver IL-10/IFN-γ double producer cells were one of the major IL-10-producing cells found, more than the percentages found inside the spleen, as found by us and other groups studying cytokine production inside the spleen after infection [52]. Here, IFNG is linked to infection.
