on the phenotype of dendritic cells (DC) and their function and the role of 1
25-Dihydroxyvitamin D
3
treated DC in asthmatic airway inflammation. Methods DC were harvested by differentiating mouse borrow cells in vitro. The effect of 1
25-Dihydroxyvitamin D
3
on phenotype of DC and their secretion of cytokines IL-10 and IL-12 was determined by flow cytometry and ELISA. Pathological changes and bronchoalveolar lavage fluid (BALF) cell types of OVA-sensitized mouse transferred by 1
25-Dihydroxyvitamin D
3
tr
eated DC were observed. Results After DCs were treated by 1
25-Dihydroxyvitamin D
3
the expressions of CD80 and MHCⅡ were decreased
whereas the expressions of CD11c were not changed. The secretion of IL-10 was increased
but that of IL-12 was decreased. Typical pathological changes of asthma were not seen in lung tissues of transferred mouse. The BALF cell types were not significantly changed as compared with blank control. Conclusion 1
25-Dihydroxyvitamin D
3
inhibits DC maturation. Adoptive transfer of DCs treated with 1
25-Dihydroxyvitamin D
3
into OVA-sensitized mouse induces antigen-specific immune tolerance
avoiding the onset of asthmatic airway inflammation.
