Biochemical analysis of the N-glycosylation pathway in baculovirus-infected lepidopteran insect cells.

abstract：:Little is known about antigen-specific T-cell responses to viruses in teleosts due to a lack of a suitable experimental system using inbred or clonal animals. In the present study we have successfully induced an in vitro generation of virus-specific cytotoxic T-cells (CTLs) from isogeneic ginbuna crucian carp. Respond...
