This study aimed to clarify the toxicity effects of 3-monochloro-1,2- propanediol(+) (3-MCPD(+)) on activated T cell in mice. The toxicity effects of 3-MCPD (+) on murine T lymphocyte responses were evaluated in vitro and in vivo. The data showed that 3-MCPD(+) markedly inhibited ConA-induced T lymphocytes proliferation, Th1/Th2 cytokines production, activated Ca2+/ CaM/I-κB-NF-κB and Ca2+/CaM/CaN/NFAT signal transduction pathways in vitro. Furthermore, administration of 3-MCPD significantly inhibited T cell-mediated DTH response in vivo. These observations indicated that 3-MCPD (+) exhibited suppressive effects on activated mouse T cell in vitro and in vivo.
