PURPOSE The peptides derived from ideal cancer-testis antigens, including LY6K, CDCA1, and IMP3 (identified using genome-wide cDNA microarray analyses), were used in immunotherapy for head and neck squamous cell cancer (HNSCC). In this trial, we analyzed the immune response to and safety and efficacy of vaccine therapy. EXPERIMENTAL DESIGN A total of 37 patients with advanced HNSCC were enrol...
The formulation of a broadly protective vaccine to prevent the serogroup B Neisseria meningitidis (MenB) disease is still an unmet medical need. We have previously reported the induction of bactericidal and protective antibodies against MenB after immunization of mice with a phage-displayed peptide named 4 L-5. This peptide mimics a capsular polysaccharide (CPS) epitope in MenB. With the aim of...
Colorectal cancer is the third most common cause of cancer-related deaths and the second most prevalent (after breast cancer) in the western world. High metastatic relapse rates and severe side effects associated with the adjuvant treatment have urged oncologists and clinicians to find a novel, less toxic therapeutic strategy. Considering the limited success of the past clinical trials involvin...
Many studies are currently investigating the development of safe and effective vaccines to prevent various infectious diseases. Multiple antigen-presenting peptide vaccine systems have been developed to avoid the adverse effects associated with conventional vaccines (i.e., live-attenuated, killed or inactivated pathogens), carrier proteins and cytotoxic adjuvants. Recently, two main approaches ...
Significance HIV is a highly mutable pathogen that can mutate to evade vaccine-induced immune responses, thus negating the vaccine’s protective effects. If mutations responses incur fitness penalty for virus, other evolve partially compensate loss. Accounting such effects, we designed single long peptide immunogen comprised of parts proteins wherein would be difficult without penalties virus. T...
Healthy persons manifest a high frequency of T cells reactive to epitopes of the self 60-kDa heat-shock protein (hsp60) molecule. It was reasoned that a self hsp60 peptide, p458m, might provide T cell help for a response to the T independent capsular polysaccharide of Streptococcus pneumoniae type 4 (PS4). The conjugate vaccine (PS4-p458m) induced resistance to challenge with >300,000 times the...
This study presents a rational design approach to discovery synthetic peptide vaccine candidates from endogenous proteins for chronic non-infectious diseases immunological therapeutics. The approach described the screening of key antigenic amino acid residues of the interleukine-13, which is up-regulated expression in asthma, followed by the development of immunological helper epitope peptides ...
Classically all vaccines were produced using live or attenuated microorganisms or parts of them. However, the use of whole organisms, their components or the biological process for vaccine production has several weaknesses. The presence of immunologically redundant biological components or biological impurities in such vaccines might cause major problems. All the disadvantageous of traditional ...
Emergence of drug-resistant strains of the pathogen Mycobacterium tuberculosis (Mtb) and the ineffectiveness of BCG in curtailing Mtb infection makes vaccine development for tuberculosis an important objective. Identifying immunogenic CD8+ T cell peptide epitopes is necessary for peptide-based vaccine strategies. We present a three-tiered strategy for identifying and validating immunogenic pept...
conclusions the results revealed that the novel multi-epitope dna construct could be an effective candidate in tuberculosis vaccine development, and it is qualified to investigate its potential to induce cd4 and cd8 t- cell immune response in the experimental animal model. results mhc class i-and class ii-predicted epitopes showed a high potential to binding to human hlas alleles, with global b...
