- Abstract
We have previously shown in mice that antibodies can be induced to synthetic malaria peptides conjugated to mycobacterial antigens. such as purified protein derivative (PPD) or heat shock proteins (hsp), and given in the absence of adjuvants after a previous priming with bacille Calmette-Guérin (BCG). In the present study we investigated this model of immunization in the non-human primates, Saimiri sciureus monkeys. Monkeys primed with BCG subcutaneously and then immunized subcutaneously with the Plasmodium falciparum sporozoite (NANP)40 synthetic peptide conjugated to PPD or mycobacterial hsp of 65 or 70 kD, in the absence of adjuvants, produced anti-peptide and anti-sporozoite IgG antibodies. Interestingly, the carrier effect of the hsp of 70kD for the induction of anti-(NANP)40 antibodies was also observed in the absence of a previous priming with BCG. These data suggest that such a vaccination strategy may be applied to humans.
