Abstract

We investigated the effect of several chlorinated organic solvents on antigen-induced histamine release and inflammatory mediator production. Non-purified rat peritoneal mast cells (NPMC) and rat basophilic leukemia (RBL-2H3) cells were sensitized with anti-dinitrophenol (DNP) monoclonal IgE antibody, and then stimulated with DNP-conjugated bovine serum albumin (DNP-BSA) and several chlorinated organic solvents. Trichloroethylene (TCE) and tetrachloroethylene (PCE) enhanced histamine release from antigen-stimulated NPMC and RBL-2H3 in a dose-dependent manner. In addition, TCE and PCE increased IL-4 and TNF-α production from antigen-stimulated RBL-2H3. In an in vivo study, we investigated the effect of TCE and PCE on passive cutaneous anaphylaxis (PCA) reaction. TCE and PCE enhanced PCA reaction markedly. These results suggest that TCE and PCE increase histamine release and inflammatory mediator production from antigen-stimulated mast cells via the modulation of immune responses. In addition, exposure to TCE and PCE may lead to the augmentation of allergic diseases.
