Using parental FVB mice and their neu transgenic counterparts, FVBN202, we showed for the first time that dangerous hyperplasia of mammary epithelial cells coincided with breaking immunological tolerance to the neu “self” tumor antigen, though such immune responses failed to prevent formation of spontaneous neu-overexpressing mammary carcinoma (MMC) or(More)
We investigated the ability of a plasmid-derived IL-21 delivered alone or in combination with the IL-15 gene to regulate immune responses to the HIV-1 envelope (Env) glycoprotein induced by DNA vaccination. Mice were injected with the gp140DeltaCFI(HXB2/89.6) vector expressing a modified Env glycoprotein with C-terminal mutations intended to mimic a fusion(More)
The GD2 ganglioside expressed on neuroectodermally derived tumors, including neuroblastoma and melanoma, is weakly immunogenic in tumor-bearing patients and induces predominantly immunoglobulin (Ig)-M antibody responses in the immunized host. Here, we investigated whether interconversion of GD2 into a peptide mimetic form would induce GD2 cross-reactive IgG(More)
The magnitude and breadth of cytotoxic-T-lymphocyte (CTL) responses induced by human immunodeficiency virus type 1 (HIV-1) envelope protein from which the hypervariable V3 loop had been deleted (DeltaV3) were evaluated in the HLA-A2/K(b) transgenic mice. It was demonstrated that vaccines expressing the DeltaV3 mutant of either HIV-1(IIIB) or HIV-1(89.6)(More)
Induction of cross-reactive cellular and humoral responses to the HIV-1 envelope (env) glycoprotein was examined after DNA immunization of BALB/c mice with gp140(89.6)-derived constructs exhibiting partial or complete deletions of the V1, V2, and V3 domains. It was demonstrated that specific modification of the V3 loop (mV3) in combination with the(More)
We have generated a codon-optimized hGagp17p24-Polp51 plasmid DNA expressing the human immunodeficiency virus type 1 (HIV-1) Gag-Pol fusion protein that consists of clusters of highly conserved cytotoxic T lymphocyte (CTL) epitopes presented by multiple MHC class I alleles. In the hGagp17p24-Polp51 construct, the ribosomal frameshift site had been deleted(More)
OBJECTIVES Immunity to the human immunodeficiency virus type-1 (HIV-1) G/P-92 fusion protein consisting of highly immunogenic regions of Gag (p17 and p24) and Pol (p51) expressed in recombinant vaccinia virus (vG/P-92) was compared with responses to the entire viral Gag-Pol precursor protein (vVK1). STUDY DESIGN/METHODS We analyzed the level of Gag and(More)
