CD1dhigh cells transplanted from infected mice into ovalbumin-primed mice made these develop less airway inflammation, less goblet cell hyperplasia, less eosinophilia, and lower values of IL-4, IL-5, IL-13, and eotaxin and higher values of IL-10 in bronchoalveolar lavages, in contrast to mice that received no cells or CD1dlow cells. The gene discussed is IL5; the disease is Increased total eosinophil count.
