Cea gene was transferred into human dcs, and specific anti - cancer effecs induced by the vaccine was observed. this test is part of my tutor ' s. hang you - tian has observed the induction of crcinembryonic antigen ( cea ) - specific cytotoxic t - lymphocyte responses in vitro when he transfected dcs with pcdna3 - cea, and has observed the immunity effects of the dcs ( pcea ) inoculateing against to ct 26 ( hcea + ) loaded in balb / c mice. after vaccination with the cea gene - modified dc, the survival time of the mice vaccinated with ct26 + ( cea + ) ws prolonged more potently than that of the mice vaccinatd with other dcs
