Attenuation on cytotoxic activities of T lymphocytes and NK cells against transgened hepatic cells by a recombinant adenovirus vector expressing US3 gene
Objective To investigate the activity of immune evasion induced by a recombinant adenovirus vector expressing US3 gene in HL-7702 hepatic cells with transferred gene.Methods We first constructed an adenovirus vector expressing US3 gene and transferred it into HL7702 hepatic cells.Then immunological activities of US3 were determined by testing outivities of T lymphocytes(CTL)and natural killer(NK)cells.Results r-US3 and r-Track were successfully constructed.r-US3 could attenuate the activities of CTL and NK ...
