1.   The hope is that these peptides might compete with the virus proteins for binding to the receptor molecules.

2.   Studies of the in vitro microcytotoxicity assays, however, have suggested hepatitis B virus capsid protein, rather than envelope protein, as a target viral antigen.

3.   For example, for bluetongue virus seven viral proteins are incorporated into virions.

4.   The vectors were utilized to express bluetongue virus proteins.

5.   Infected cells identify themselves by displaying pieces of the internal virus proteins.
