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 C57 BL /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...
