Viral IL-10 gene transfer at day − 1 inhibits proinflammatory cytokine production to IRBP by IRBP-stimulated spleen cells. Cytokine production to IRBP in culture was measured by ELISA. No production of IL-10 or IL-4 was detected in the limits of sensitivity of the ELISA test (respectively, 20–50 pg/ml and 5–10 pg/ml), but small bars were represented to illustrate these data. No production of cytokine was obtained with unstimulated cells in the different tests. , IFN-γ; □, IL-10; ▪, IL-2;
