To identify malaria antigens for vaccine development, we selected alpha-helical coiled coil domains of proteins predicted to be present in the parasite erythrocytic stage. The corresponding synthetic peptides are expected to mimic structurally "native" epitopes. Indeed the 95 chemically synthesized peptides were all specifically recognized by human immune sera, though at various prevalence. Pep...
Significant genetic variability in the head region of the influenza A hemagglutinin, the main target of current vaccines, makes it challenging to develop a long-lived seasonal influenza prophylaxis. Vaccines based on the conserved hemagglutinin stalk domain might provide broader cross-reactive immunity. However, this region of the hemagglutinin is immunosubdominant to the head region. Peptide-b...
The cancer-testis antigen NY-ESO-1 is one of the most promising candidates for generic vaccination of cancer patients. Here we analyzed the CD8(+) T cell response to a NY-ESO-1 peptide vaccine composed of the two previously defined peptides 157-165 and 157-167, administered with GM-CSF as a systemic adjuvant. The NY-ESO-1 peptide vaccine elicited a CD8(+) T cell response directed against multip...
The synthetic oligodeoxynucleotide CpG 7909, which contains unmethylated cytosine/guanine (CpG) motifs, has potent immunostimulatory effects when coadministered with NY-ESO-1 peptides or recombinant NY-ESO-1 protein, resulting in an enhanced cellular and humoral immune response against the vaccine antigen. In this study, we report the development of anti-CpG-ODN antibodies in 21 of 37 patients ...
No. down6848 Beamline(s): X28C The inability of current vaccines to offer complete protection and the increasing number of infectious disease for which no vaccine exists has prompted the development of new immunogens. Synthetic peptides based on the determinants of protein antigens can be used as immunogens and offer improvements over traditional preparations. However, peptides alone are usuall...
Background: Recently, with the advances in the medicine of boosting the immune system, high ability of peptides for the treatment of viral diseases has been proved. By now, there is no effective vaccine against HIV-1 infection. Previous studies confirmed the efficiency of capsid and envelope proteins of papilloma, Herpes and Adeno viruses in new vaccines design. The present study was planned to...
By using the published amino acid sequence for mature outer membrane protein F of Pseudomonas aeruginosa, a computer-assisted analysis was performed to identify sites with potential as surface-exposed, antigenic regions located throughout the length of the protein molecule. Synthetic peptides 13 to 15 amino acid residues in length were synthesized for 10 such regions. Mice were immunized with e...
objective(s):tumor-associated antigen (taa) subunit-based vaccines constitute promising tools for anticancer immunotherapy. however, a major limitation in the development of such vaccines is the poor immunogenicity of peptides when used alone.the aim of this study was to develop an efficient vaccine delivery system and adjuvant to enhance anti-tumor activity of a synthetic her2/neu derived pept...
