Twenty-five patients with high-risk resected stages IIB, III, and IV melanoma were immunized with a vaccine consisting of the minimal epitope, immunodominant 9-amino acid peptide derived from the MART-1 tumor antigen (AAGIGILTV) complexed with incomplete Freund's adjuvant. The last three patients received the MART-1(27-35) peptide with incomplete Freund's adjuvant mixed with CRL 1005, a block c...

Induction of high levels of broadly reactive cytotoxic T lymphocytes (CTL) remains a promising approach for an effective HIV-1 vaccine. We have developed a novel genetic-based vaccine strategy that encodes consensus overlapping peptide sets from all HIV-1 proteins scrambled together. This synthetic scrambled antigen vaccine (SAVINE) strategy has significant advantages, e.g. capacity to encode m...

Serogroup B is the only major disease-associated capsular group of Neisseria meningitidis for which no protein-polysaccharide conjugate vaccine is available. This has led to the development of multi-component protein-based vaccines that target serogroup B invasive meningococcal disease (IMD), including Bexsero®, which was implemented for UK infants in 2015, and Trumenba®. Given the diversity of...

The development of a protective cellular immune response against human cytomegalovirus (HCMV) is the most important determinant of recovery from HCMV infection after allogeneic bone marrow transplantation (BMT). The ultimate aim of our study is to develop an antigen-specific and peptide-based vaccine strategy against HCMV in the setting of BMT. Toward this end we have studied the cellular immun...

Given the increasing interest in use of peptide- and protein-based agents therapeutic strategies, it is fundamental to develop delivery systems capable preserving biological activity these molecules upon administration, which can provide tuneable release profiles. Electrohydrodynamic (EHD) techniques, encompassing electrospinning electrospraying, allow generation fibres particles with high surf...

To develop a peptide vaccine for cancer patients with the HLA-A26 allele, which is a minor population worldwide, we investigated the immunological responses of HLA-A26(+) /A26(+) cancer patients to four different CTL epitope peptides under personalized peptide vaccine regimens. In personalized peptide vaccine regimens, two to four peptides showing positive peptide-specific IgG responses in pre-...

Background and Aims: Influenza vaccine production process is time-consuming with little-to-no cross-protection which requires annual adjustment. The construction of a universal vaccine to deal with the pandemics and epidemics which occasionally threat human population is the aim of many researches worldwide. Today, influenza vaccines are mostly against two major antigenic proteins, hemagglutini...

Traditional bolus vaccines often fail to sustain robust adaptive immune responses, typically requiring multiple booster shots for optimal efficacy. Additionally, these provide few opportunities control the resulting subclasses of antibodies produced, which can mediate effector functions relevant distinct disease settings. Here, it is found that three scaffold-based vaccines, fabricated from pol...

PURPOSE Dendritic cell (DC)-based cancer vaccines is a newly emerging and potent form of immune therapy. As for any new technology, there are still considerable challenges that need to be addressed. Here, we investigate the antitumor potential of a novel liposomal vaccine, M/CpG-ODN-TRP2-Lipo. METHODS We developed a vaccination strategy by assembling the DC-targeting mannose and immune adjuva...
