| Popis: | The structural similarities between polybrominated diphenyl ethers and immunotoxic halogenated aromatic compounds suggest that the polybrominated diphenyl ethers might affect the immune system. The present study was undertaken to investigate the immunological effects of some purified PBDE-congeners on human lymphocyte function in vitro. Polychlorinated biphenyl congeners were also included in the study. Mitogen-induced DNA synthesis and immunoglobulin synthesis by lymphocytes from blood donors were examined following polybrominated diphenyl ether or polychlorinated biphenyl exposure in vitro in order to determine the immunotoxic potential of these substances. No effects on mitogen-induced proliferation or immunoglobulin synthesis were observed after exposure of cells to concentrations up to 10(-5) M. The negative findings in this study indicate that certain functions of human peripheral lymphocytes, i.e. proliferation and immunoglobulin synthesis, are insensitive to the direct action of polybrominated diphenyl ethers and polychlorinated biphenyls. Our results are in accordance with other recent studies in which no effects on immunological parameters were demonstrated by exposure of lymphocytes to polyhalogenated aromatic hydrocarbons in vitro. |
