Enhanced cellular immune response against SIV Gag induced by immunization with DNA vaccines expressing assembly and release-defective SIV Gag proteins.

Abstract excerpt

Codon-optimized genes were synthesized for the SIVmac239 Gag, a mutant Gag with mutations in the major homology region, and a chimeric Gag containing a protein destruction signal at the N-terminus of Gag. The mutant and chimeric Gag were expressed at levels comparable to that observed for the wild-type Gag protein but their stability and release into the medium were found to be significantly reduced. Immunization...
