- AB We investigated the specific priming of MHC class I-restricted cytotoxic
- T lymphocytes (CTL) by different protein antigen preparations in mice.
- The recombinant viral protein antigens tested are of potential relevance
- for the design of subunit vaccines. They include the hepatitis B virus
- (HBV) surface antigen (S-antigen), the HIV-1 gp160 envelope protein, and
- a chimeric HIV-1 Pr55-gag/V3-3 retrovirus-like particle. In addition,
- ovalbumin (OVA) was tested. The native or denatured particulate
- (multimeric) or monomeric form of these protein antigens was injected by
- various routes into mice. Class I-restricted CTL were efficiently primed
- by a single low-dose injection of HBV S-antigen particles or the
- chimeric HIV-1 Pr55-gag/V3-3 particles. After SDS-denaturation,
- gel-purified monomeric S-antigen and monomeric Pr55-gag/V3-3 fusion
- protein were still very efficient in priming CTL. CTL sensitization was
- not detected in a (primary or boosted) response to even high doses of
- native OVA or native HIV-1 gp160. Denaturation of these two antigens by
- detergent strikingly increased their immunogenicity for CTL.
- Immunization of mice with non-treated or SDS-denatured antigenic
- peptides representing the relevant CTL-defined epitopes of the tested
- protein antigens did not prime CTL. These data indicate that native,
- particulate and denatured, monomeric protein antigens efficiently
- stimulate a class I-restricted CTL response.
