		WANG Yun-yun1, JIANG Yu-ping2, ZHANG Biao1, GU Zong-jiang1
		Objective: To investigate the effect of interaction between B and T lymphocyte attenuator (BTLA） and HVEM of mouse bone marrowderived dendritic cells（BMDC）on T cell activation. Methods: T cells and BMDC from C57BL/6 mouse were mixed and cultured. After blocking HVEM on BMDC by antibodies against HVEM, MTT method was used to examine T cell proliferation and the secretion of IL2 was tested by ELISA kit. Results: In the priming and early phase (0-48 h), or middle and later phase (48-96 h), or all phase (0-96 h) of mixing culture, the proliferation of T cells from experimental groups with addition of HVEM antibodies was higher compared with control groups (P<0.05), and the secretion of IL2 from CD3+T cell and CD4+ T cell groups was also higher compared with control groups (P<0.05). Conclusion: The negative signal produced by interaction between BTLA and HVEM played the inhibition role in T cell activation. Especially in the priming and early phase (0-48 h) of mixing culture of T cells and BMDC, the negative signal from BTLA already played such inhibition role, exhibiting another negative regulation mode different from traditional negative feedback regulation mode and suggesting the existence of multiple negative regulation for T cell activation.

Methods: DOP (1 000 mg/kg,i.g.) and As (10 mg/L,p.o.) were administered individually and as mixtures to 4 groups of mice. After 8 weeks of exposure, the enzyme activity, learning and memory abilities and As content in brain of mice were assessed by commercial kits, Morris water mase test and VistaMPX Simultaneous ICPOES.The expression of Bax, Bcl2 and Caspase3 were performed by Western blot. Results: Mice demonstrated poorer learning and memory performance in exposure groups compared to control.The As level of brain in exposure groups were significantly increased (P<0.05). AChE and SOD activities decreased, however,MDA and NOS showed an increase in exposure groups compared to control. The expression of caspase3 and Bax were significantly increased but Bcl2 expression was inhibited in the hippocampus, and Bax/Bcl2 increased. Conclusion: Both DOP and As can induce neurotoxicity in mice associated with hippocampal apoptosis which caused by oxidative stress. The joint toxicity of DOP and As was complicated. Effect of antagonism, synergistic or without interaction were all observed. The mechanism needs to be further studied.
