OVA/Alum sensitized and OVA challenged iIL-15 mice show dose dependent decrease of body weight (A) and occurrence of diarrhea (B) compared to the sensitized and challenged WT mice. No weight gain or loss was observed in sensitized and saline challenged WT and iIL-15 mice (A, B). Both WT and iIL-5 mice show comparable number of mast cells in saline and OVA challenged mice (C). OVA challenged mice detected induced jejunum eosinophilia compared to WT mice (D). The mRNA levels of IL-4, IL-5, IL-13, IL-18, TNFα and MUC5A in the jejunum region of saline or ova challenged WT and iIL-15 mice (F-K). The data was expressed as mean ± SD; Experiment “n”= 2, 3 mice/group.
