IL-4 reconstitutes early and late CS responses in NKT cell–deficient mice. (A) WT 1-d PCl immune mice (Group A) were compared with 1-d immune CD1d−/− mice (Group B) as recipients of 4-d PCl immune T cells from CD1d+/+ mice. WT immune mice elicited 2 and 24 h CS (Group A), whereas the CD1d−/− mice did not (Group B). Groups C–E are identical to Group B. However, these 1-d immune CD1d−/− mice that received isolated immune T cells also were injected with different doses of rIL-4 during immunization. *P < 0.05; **P < 0.001. (B) WT BALB/c 1-d active PCl immune mice (Group B) were compared with 1-d immune Jα18−/− (Group C) as recipients of 4-d PCl immune magnetic-separated T cells from BALB/c mice. Group D is identical to Group C, but 20 ng i.v. of IL-4 was injected during immunization of the 1-d immune Jα18−/− recipient mice. In A and B, the results are mean ± SE from four mice per group.
