| Research Abstract |
The supernatants of human basophils stimulated with the Japanese cedar pollen antigen induced TSLP production from airway fibroblasts significantly. Antigen specific IgG (high concentration), or the chimeric molecule suppressed TSLPproduction from airway fibroblasts cultured with supernatants of stimulated humanbasophils. Histamine significantly increased TSLP production from airway fibroblasts inthe presence of IL-4. Anti-IL-4Ra (CD124) blocking antibodies or anti-histamine (H_1)receptor antibody decreased TSLP production from fibroblasts with supernatants ofstimulated human basophils. Also, we found that the cedar antigens induced the production of IL-13 and IL-4, and histamine release from human basophils.
