We have developed a comparative study of antigenic and immunogenic properties of selected immunodominant HIV-1 epitopes from p24 and gp120 proteins added to C-terminally truncated hepatitis B virus (HBV) core protein and exposed on the surface of chimeric core particles. Inserted p24 (121-210) and gp120/MN (306-328) epitopes induced the appropriate humoral and cellular immune responses against HIV-1. Superficially exposed region 160-192 of p24 also showed maximal B cell immunogenicity whereas buried region 148-162 induced maximal T cell response. Both recombinant proteins were also able to be recognized in vitro by T lymphocytes of HIV-1 asymptomatic carriers.
