| Outline of Final Research Achievements |
The evaluation method for the sensitization of food additives using human monocytic THP-1-derived DCs (TDDCs) by culturing with PMA and IL-4 was developed. The expression levels of HLA-DR (MHC class II) and CD86 (costimulatory molecule) were measured as an indicator of antigen presentation in TDDCs. When TDDCs were stimulated with OVA in the range of 0.01-0.5 mg/mL, The expression of HLA-DR and CD86 were dose-dependently increased compared with the control cells. The addition of obomucoid, beta-lactoglbulin, Fag e1 on the TDDCs also gave the similar results. The production of chemokines such as RANTES and CCR7 also increased by the addition of food antigens. The sensitization of food additive enzymes and hapten allergens were evaluated using the developed method.
