(A-E) B6 mice containing a small number of naive P14 CD8+ T cells were immunized with DC-33 alone or in combination with LPS, MPLA or CpG-B. Serum samples were collected 6 and 18 hours post immunization. Cytokine and chemokine production was measured by Luminex multiplex assay. Bar graphs show the amounts of IL-12, IFNγ, IL-6, IL-10 and IL-1β produced post immunization. (F) B6 mice containing a small number of WT or IL-12Rβ2−/− P14 CD8+ T cells were immunized with DC-33 in combination with MPLA. At day 7, the frequency of splenic Thy1.1+ P14 CD8+ T cells and their expression of KLRG1 and IL-7R were analyzed. Data shown are representative of two independent experiments.
